My Intern Experience
During my time as an undergraduate, one of the key experiences recommended is to do an internship. Gaining work experience as an intern overseas will improve a skill set in my area of interest. Working somewhere as culturally different and economically significant as China is a talking point in any interviews. There are many reasons that made me choose to do an internship in China. Definitively the best part of the experience has been living out of your comfort zone. Encountering new situations and experiences, that increase my self awareness, my capabilities and also to discover my weaknesses.
Over the past 2 years, we have seen many digital currencies/cryptocurrencies being introduced globally.These have added the aspect of using this financial ecosystem to eventually solve social issues. This could be the application of Blockchain technology in areas like logistics/supply chain to food security. Eventually, there would be many more areas where blockchain and related technology developers would be needed. It's emerging to change the way we solve the many roadblocks that we face.
Blockchain is considered to be one of the most trending topics. This is the right time for me to learn about the technology and start implementing. Blockchain is a notion that can be implemented directly or indirectly to any sector as such. Only two months prior, I had a minimal amount of knowledge about blockchain innovation, and my insight into blockchain comprised distinctly of an obscure comprehension of bitcoin and cryptographic money all in all.
During my internship, I was given investigation material to help assemble my base comprehension of Loopring and the blockchain innovation that it depends on. In the wake of beginning at Loopring, I have been given significantly more prominent chance to learn. While my comprehension of blockchain is still new, it has improved extensively since my first day at the organisation.
In this post, I would like to talk about two cryptographic methods aiming to give privacy to blockchain technology ; the zk-SNARKS and zk-STARKS protocols are two significant examples. We will look into their advantages and disadvantages, comparison between two protocols, and conclusion.
ZK-SNARKS vs ZK-STARKS
Along with the countless benefits of the Internet from which we can benefit, when we use it for social media or business company purposes, privacy is at greater risk. Approximately 90 million of Facebook users information were damaged by Cambridge Analytical data. The Wall Street stated that “ this is just the beginning, and the results are expected to grow”. The Equifax data breach revealed information on social media channels from private users. Thus, birth dates were exposed to the majority of the populations. Due to the Uber hack, data from over 55 million customers were also shared and exposed.
Privacy has consistently been seen as a valuable element within the cryptocurrency community. There is always a growing focus on improving privacy within the cryptocurrency space. Bitcoin, Ethereum, Litecoin and many other cryptocurrencies are all actively searching for the most convenient approaches to increase their security. It is the antecedent to fungibility, which is vital for a broadly used form of money. Additionally, most crypto-asset holders do not want their transaction history to be completely public to the world. Among the different cryptographic methods aiming to give privacy to blockchain technology; the zk-SNARK and zk-STARKS protocols are two main significant examples.
Two leading technologies today offer their cryptocurrencies - Monero and zcash— and strive to address protection issues. Monero uses the technology of Ring Confidential Signature. By contrast, Z-Cash uses zk-SNARK( Zero-Knowledge transparent knowledge argument), a technology that provides the ability to conduct anonymous transactions.
In recent years, zk-SNARKS has exploded as the most promising technology to solve blockchain privacy. It is a technology derived from proofs of zero-knowledge, a type of proof that anyone with a verification key can check this “proof” without disclosing the information itself. If the statement holds, a verifier will be convinced by a correct proof. If the statement is false, it is true that no prover can convince a verified statement.
zk-SNARK stands for :
- Zero-knowledge : if the statement is true, there is nothing the verifier learns beyond the fact that the statement is true.
- Succinct : The proof size needs to be small enough in a few milliseconds to be verified.
- Non-interactive :Only one set of information is sent to the verifier for verification, therefore there is no back and forth communication between the prover and verifier.
- Argument of Knowledge : A computationally soundproof: soundness runs counter to a prover leveraging polynomial-time, i.e. limited computing. Also, Without access to the witness (the private input needed to prove the statement), the evidence can not be constructed.
zk-SNARKS aims to provide fast, scalable solutions to ensure financial security. Therefore, transaction encryption is possible.When zk-SNARK is applied to a cryptocurrency, it implies you can conceal the majority of the transaction data information. This incorporates the sender address, collector address, just as the transaction sum amount. zk-SNARKS enables us to shroud the majority of this data information, while likewise enabling the system to affirm and verify the transactions. It amplifies security while maintaining consensus. In the realm of blockchain, it is one of the most exceptional blockchain level protection innovation being used.
With the launch of version 3.0, Loopring’s decentralised protocol solution struck a noteworthy milestone in early May- adding off-chain scaling and fee optimisation using zk-SNARKs. Low fees, liquidity, transparency and security are the key goal of the loopring solution. Loopring says the new Loopring 3.0 based zk-SNARK will increase trade speeds and on-chain activity efficiency tenfold. The data previously stored on-chain in Loopring 3.0 is now stored off-chain in a Merkle tree and then used as required in zk-SNARKS, updating the tree.
Be that as it may, there are a few issues with zk-SNARKS. The main problem has been the need for a trusted setup. zk-SNARKS rely on a permission private key. This essentially undermines the entire purpose of decentralised public blockchain. By introducing the need to trust a person rather than code, you threaten the entire concept of trustlessness. In theory, a prover with sufficient computational power could create fake proofs, and this is one of the reasons why many consider quantum computers as a threat to zk-SNARKs (and blockchain systems).
Last year zk-SNARKS were incorporated on a MIT Tech Review list of the top 10 Breakthrough Technologies of 2018 among AI advancements. zk-SNARKS allows both a tremendous speedup in verifying the correctness of a computation while at the same time it hides the private details from prying eyes. Some of the potential uses citied in MIT article were verifying you’re over 18 without having to share your date of birth, and providing you have a enough money in your back account as collateral without having to give away account details like your exact balance. It establishes trust which you need to interact on the blockchain. Zk-SNARK proofs are as of now being used on Zcash, on JP Morgan Pursue's blockchain-based payment system, and as an approach to safely validate customers to servers.
The more developed version of zk-SNARKS is called zk-STARKS which stands for :
Zero-Knowledge
Scalable
Transparent
Argument of Knowledge
zk-STARKS verifications are currently being touted as the better than ever form of the convention, tending to a considerable lot of the past disadvantages of zk-SNARKs. It has demonstrated an approach to accomplish a similar degree of privacy as zk-SNARKS without the requirement for the trusted setup. Starks are practically superior to Snarks as they require weaker crypto suppositions, they don't require a trusted setup and are post-quantum resistant. zk-SNARKs are based on Elliptic-Curve Cryptography, which is susceptible to advances in Quantum-Computers. zk-STARKs, on the other hand are Post-Quantum system meaning that even if Quantum-computers become powerful and ubiquitous they will not have an advantage, compared to classical computers, in breaking zk-STARKs. Anyway they have a noteworthy downside, as in the proof being too enormous. Their problem is their storage requirements. STARKs are doubly scalable, which means the proof verification is exponentially faster than the original computation’s time but the drawback is the size of the proof they create being too large, possibly 2 or 3 orders of magnitude more than those produced by zk-SNARKs. One example : StarkWare solves the inherent problems of scalability and privacy of blockchains. Using STARK technology, they generate a full proof-stack to produce and verify computer integrity tests. They utilise STARKs to batch transactions into a single proof that is verified on Ethereum. Matt Taylor states that the present iteration of StarkDEX demonstrates the viability of using STARKs for the scalability of Layer-2 by showing a substantial rise in the amount of blockchain transaction.
The idea of zk-STARKS was proposed by Eli-Ben Sasson, a professor at the Technion-Israel institute of Technology. zk-STARKS provide proofs that can be verified a lot quicker than zk-SNARKS. At the present time, Z-cash and Ethereum are on the whole considering to utilize zk-STARKS. zk-STARKS have solved the trusted setup issue. They have totally expel the requirement for multiple parties to create the private key required for the string. Rather everything needed to produce the proofs is public and the verifications are generated from arbitrary numbers. zk-STARKS actually removed the necessity in zk-SNARKS for unbalanced cryptography and rather utilizes the hash fuctions like those found in Bitcoin mining. In addition, they ought to have longer timeframe of realistic usability as far as their crytographic resilience than zk-SNARKS. However, there are some impediment of zk-STARKS, the main issue with zk-STARKS is their size. The verifications it uses are basically too enormous to use in many blockchains as they stand. As indicated by Vitalik Buterin, zk-STARKS will result in proofs of a couple of hundreds kilobytes versus the 288 bytes seen in zk-SNARKS.

The Difference Between zk-STARKS and zk-SNARKS.

The complexity of communication : With the computation’s expanded complexity, the zk-SNARKS communication complexity also increases linearly, whereas zk-STARKs develops in the opposite direction and grows slowly as the computation size grows.The graph above shows that the communication required by the zk-STARKs to complete the calculation rises much slower than zk-snarks as the underlying evidence increases in complexity.

Source : The Medium - Coinmonks
The complexity of the verifier : zk-STARKs slightly widening with the development in computation size. On the other side, for confirmation evidence, zk-SNARKs requires less time than zk-STARKs. zk-STARKs, for instance need up to 100 ms to verify and zk-SNARKs need only up to 10ms. The graph above illustrates the the time taken by the zk-STARK to verify an evidence rises very slowly compared to the zk-SNARK as the underlying evidence increases in complexity.

Overall these two protocols have excellent potential in the cryptocurrency globe and can be a breakthrough avenue for mainstream implementation. Both conventions are truly needed steps to protect our privacy.

Decred Journal – August 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link) to see all the links.

Development

dcrd: Version 1.3.0 RC1 (Release Candidate 1) is out! The main features of this release are significant performance improvements, including some that benefit SPV clients. Full release notes and downloads are on GitHub.
The default minimum transaction fee rate was reduced from 0.001 to 0.0001 DCkB. Do not try to send such small fee transactions just yet, until the majority of the network upgrades.
Release process was changed to use release branches and bump version on the master branch at the beginning of a release cycle. Discussed in this chat.
The codebase is ready for the new Go 1.11 version. Migration to vgo module system is complete and the 1.4.0 release will be built using modules. The list of versioned modules and a hierarchy diagram are available here.
The testnet was reset and bumped to version 3.
Comments are welcome for the proposal to implement smart fee estimation, which is important for Lightning Network.
@matheusd recorded a code review video for new Decred developers that explains how tickets are selected for voting.
dcrwallet: Version 1.3.0 RC1 features new SPV sync mode, new ticket buyer, new APIs for Decrediton and a host of bug fixes. On the dev side, dcrwallet also migrated to the new module system.
Decrediton: Version 1.3.0 RC1 adds the new SPV sync mode that syncs roughly 5x faster. The feature is off by default while it receives more testing from experienced users. Other notable changes include a design polish and experimental Politeia integration.
Politeia: Proposal editing is being developed and has a short demo. This will allow proposal owners to edit their proposal in response to community feedback before voting begins. The challenges associated with this feature relate to updating censorship tokens and maintaining a clear history of which version comments were made on. @fernandoabolafio produced this architecture diagram which may be of interest to developers.
@degeri joined to perform security testing of Politeia and found several issues.
dcrdata: mainnet explorer upgraded to v2.1 with several new features. For users: credit/debit tx filter on address page, showing miner fees on coinbase transaction page, estimate yearly ticket rewards on main page, cool new hamburger menu and keyboard navigation. For developers: new chain parameters page, experimental Insight API support, endpoints for coin supply and block rewards, testnet3 support. Lots of minor API changes and frontend tweaks, many bug fixes and robustness improvements.
The upcoming v3.0 entered beta and is deployed on beta.dcrdata.org. Check out the new charts page. Feedback and bug reports are appreciated. Finally, the development version v3.1.0-pre is on alpha.dcrdata.org.
Android: updated to be compatible with the latest SPV code and is syncing, several performance issues are worked on. Details were posted in chat. Alpha testing has started, to participate please join #dev and ask for the APK.
iOS: backend is mostly complete, as well as the front end. Support for devices with smaller screens was improved. What works now: creating and recovering wallets, listing of transactions, receiving DCR, displaying and scanning QR codes, browsing account information, SPV connection to peers, downloading headers. Some bugs need fixing before making testable builds.
Ticket splitting: v0.6.0 beta released with improved fee calculation and multiple bug fixes.
docs: introduced new Governance section that grouped some old articles as well as the new Politeia page.
@Richard-Red created a concept repository sandbox with policy documents, to illustrate the kind of policies that could be approved and amended by Politeia proposals.
decred.org: 8 contributors added and 4 removed, including 2 advisors (discussion here).
decredmarketcap.com is a brand new website that shows the most accurate DCR market data. Clean design, mobile friendly, no javascript required.
Dev activity stats for August: 239 active PRs, 219 commits, 25k added and 11k deleted lines spread across 8 repositories. Contributions came from 2-10 developers per repository. (chart)

Network

Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%.
Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply.
Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.

ASICs

Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design.
Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15.
FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25.
Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).

Integrations

www.d1pool.com joined the list of stakepools for a total of 16.
Australian CoinTree added DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports.
Three new OTC desks were added to exchanges page at decred.org.
Two mobile wallets integrated Decred:
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?

Adoption

Merchants:

Marketing

Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here.

Markets

DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery.
@ImacallyouJawdy posted some creative analysis based on ticket data.

Relevant External

StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs.
The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury.
Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue)
Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack).
Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups.
Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems.
Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins.

Best Cryptocurrency Exchanges for Beginners

Best Cryptocurrency Exchanges for Beginners
Best Cryptocurrency Exchanges for Beginners
Before we get into exchanges, let’s refresh our minds about what cryptocurrency is. The concept behind cryptocurrencies is relatively simple, while the math and technology are not. Essentially, a cryptocurrency is a virtual or digital currency that utilizes cryptography as a means for protection and security.
Cryptography is also used to regulate the creation of additional units, so as to not drive the overall digital currency market wild. One of the greatest appeals of cryptocurrencies is that they are not regulated by any government agencies. The most popular digital asset is the bitcoin, followed by ethereum.

What Are Cryptocurrency Exchanges?

Cryptocurrencies can be traded through cryptocurrency exchanges. These cryptocurrency exchanges are platforms through which you can purchase or sell digital currencies for dollars, euros, and pounds, as well as other digital assets. For example, you can sell bitcoins and purchase dollars with the sold bitcoins, or you could exchange bitcoins for ether. These exchanges are a vital part of the virtual currency expansion rate.
There are private exchanges, which are exclusive and operate by invite only, as well as those available for the public. Local exchanges also exist. Some are easier to use than others are; certain exchanges are so flexible that digital assets can be traded directly through the built-in chat features of specific popular messengers, like Telegram.

What to Consider When Picking the Best Cryptocurrency Exchanges

Here are a few things you will want to consider before picking the best cryptocurrency exchange suited for your trading and speculative needs.
Fees – Almost all exchanges charge fees for you to do business on their platforms. Make sure that when you are signing up or committing yourself to a specific exchange that you know everything about its fees.
Verification Requirements and Security – These are vital to understand before starting out on an exchange. Most exchanges require some sort of identity verification in the form of a passport, driver’s license, proof of residence, or other similar document before joining. The more complex the verification process, the safer the exchange platform.
Exchange Rates – Exchange rates are also important, as you don’t want to join a cryptocurrency exchange that charges draconian fees for transactions and exchanges. That just wouldn’t be fair to you or financially savvy.
Reputation – The best cryptocurrency exchanges always have ups and downs. However, the general opinion of the top ones is positive. The best exchanges have a solid reputation and are well trusted by traders.
Region – It’s also important to find an exchange that supports your geographic region. Some exchanges may support all of the countries in South America, while not supporting any of the countries in Asia, and vice versa. If you are living in Russia, for example, make sure you pick the best exchange platform that supports your region.
Now, let’s take a look at some of the best cryptocurrency exchanges out there.

Security

Something which is important to bare in mind when choosing a cryptocurrency exchange to make your trades and purchases on is their security measures. It is well-known that many exchanges have been hacked in the past, most notably the Mt Gox exchange, which people are still feeling the fall-out from ever since.
You should know that the your funds or coins on an exchange or not really yours, unless you own the private keys to the wallet of your coins you are relying on someone else to be custodian of your funds.
Luckily there are some basic measures you can take when using an exchange. The most important is to never store more there than you are willing to lose, if you have a significant balance, you should withdraw it back to your own wallet and for extra security, use a Hardware wallet to secure these funds.
Exchanges should be used for quick purchases of your desired cryptocurrency or for trading an amount you are happy with. They should never be used as your primary wallet, that is not their intended function.
Another important step to take is to use all the security options available on the site, make sure that two-factor authentication (2FA) is setup correctly and you use an app like Authy or Google authenticator. Do not use the mobile phone option which texts you a code, this is not safe as their have been a number of high-profile hacks involving sim-swaps which allow a would-be hacker to take over your phone number and then gain access to your account.

Coinbase

Coinbase is one of the, if not the, most trusted cryptocurrency exchange platforms in the world. It is also the largest digital asset exchange platform in the world. The platform supports more than 32 countries and has more than 4 million active users. Traders are allowed to acquire and sell bitcoins using their bank account, credit card, PayPal, and other payment methods, as well. In order to begin trading on Coinbase, you will have to set up an e-wallet for buying and selling cryptocurrencies. Furthermore, users have to be able to link a valid bank account in order to purchase bitcoins.

Currently, fully verified U.S. residents are only allowed to hold up to 50,000 bitcoins per day. Overall, Coinbase has a great reputation and is highly respected in the trader community. Most transactions through Coinbase only have a 1 percent transaction fee in addition to any fees that your selected payment method may carry.
As with CEX, you can only purchase a few currencies: Bitcoin, Ethereum and Litecoin. You would then need to use Changelly to convert these to other crypto currencies.
Another benefit of registering with Coinbase is the fact you are then able to use the Coinbase Pro exchange which is owed by the same company. Coinbase Pro allows to more advanced trading features such as margin trading and Market, Limit, & Stop Orders. Coinbase Pro also has lower fees than Coinbase.
Read our full Coinbase Review here to learn more. We have also conducted a thourough look at Coinbase’s security measures here.

Binance

Binance is a newer exchange but one we have grown to love, it has a wide range of cryptocurrencies available to purchase and trade and has a basic and advanced view which you can switch between easily. Their fees are very reasonable and they allow you to register and trade immediately without having to verify your account. You will then be able to make withdrawals of up to 2 BTC per day, if you want to withdraw higher amounts you will then need to upload your photo ID and a “selfie” photo.

The public opinion of Binance at this time is very high with people praising the speed of the site, ease of use and cheap fees.

KuCoin

KuCoin is a new but very exciting exchange based in South Korea. They operate similarly to Binance in the fact that they list new altcoins much quicker than other exchanges so it’s a good place to purchase cryptocurrencies shortly after their ICO meaning there is a greater opportunity to profit by getting in early.
The interface is very clean and modern and much easier to operate than other older and more clunky exchanges.
They also offer their own token KCS which allows all holders to receive a daily share of profits of the platform, this is a great token to hold as you are paid in the many different currencies that the site allows people to trade in.

LocalBitcoins

LocalBitcoins is a peer-to-peer cryptocurrency exchange used in most big cities around the world. The general principle behind this exchange is that you can find people who live in your area or city and meet with them in person to conduct an exchange. The platform also offers options for purchasing digital currencies via PayPal, Square, direct-to-bank transfers, and many other payment-processing methods. The platform charges a small fee of 1 percent per transaction in cases where sellers apply their own exchange rate.

Similar to the way Uber passengers and drivers are rated, LocalBitcoins applies a rating to each trader that uses the platform, and this rating is publicly displayed. Trades first have to undergo an escrow process to ensure that nobody will be scammed by using the platform. Once everything is verified, the funds and cryptocurrencies transfer between traders. LocalBitcoins takes a commission of 1 percent from sellers. W

CoinMama

CoinMama is a large bitcoin brokerage that allows users to acquire coins with their debit or credit cards. The platform issues small fees for transactions. To make up for this, however, the limits for how many bitcoins a user can buy are much higher in comparison to Coinbase. Users can acquire up to $5,000 of coins per day or up to $20,000 per month. All users need to do to use CoinMama is to set up an account, log in, and navigate to the profile page section to fill in personal information.

Following this, users will be introduced to a page that allows them to select how many bitcoins they would like to purchase, and once a fitting amount has been selected, users will be allowed to add their preferred payment methods and bitcoin addresses. Users will also be required to verify their phone number and email address. CoinMama does not require most users to upload their government-issued ID. After completing the aforementioned steps and passing the verification process, users will be able to acquire bitcoins through CoinMama.

CEX.IO

CEX.IO is one of the oldest cryptocurrency exchanges in the world. However, despite being referred to as a cryptocurrency exchange, CEX.IO can only be used with bitcoins and ethereum which are the main two trading pairs for alt-coins. If you want to purchase other currencies, you can use CEX and then a service named Changelly to convert them to many other cryptos.
The platform is registered with the FINCEN and applies KYC and AML principles. In other words, users have to completely verify their identity before they can get involved in any trades with this platform. Currently, the platform supports purchases with credit cards, wire transfers, or SEPA transfers for European residents.

Once you enter a trade, the platform automatically calculates the price of the transaction and freezes the exchange rate for 120 seconds, which is quite convenient. However, many users note that there are occasional hidden fees. CEX.IO has a flat fee of 7 percent for anything involving fiat currencies. For example, if you acquire $100 in bitcoins, you will only receive $93 in coins.

Bittrex

Bittrex is well established and highly regarded crypto trading platform, with many coins and tokens to choose from. The interface is not for complete beginner’s but you should be able to find your way around after a little while.

Read our full review of Bittrex here.
Unsurprisingly, Bittrex’s most popular trading pairs are BTC and ETH. It must be noted that the exchange currently does not offer any kind of fiat-to-crypto pairs, e.g. with U.S. dollars, euros, or British pounds). One thing investors can do is buy USDT (Tether tokens) via wired bank transfers in order to use USDT for crypto-to-crypto exchanges.
However, you’ll need to be fully verified and willing to slap down at least $10,000 USD for Bittrex to even consider the transfer. And we here at Blockonomi don’t remind this approach anyways; there’s been a lot of controversy surrounding Tether lately, and it’s best just to stay away for now until further developments actualize.

4 Sub-$10 Million Market Cap Coins Worth Keeping An Eye On

1. Spectrecoin ($XSPEC) – $8.6 Million

What is Spectrecoin?

Utilizing a “range of proven cryptographic techniques” to achieve anonymous, untraceable, and un-linkable transactions, Spectrecoin is a secure Proof-of-Stake cryptocurrency enabling rapid P2P transactions and network privacy. Specifically, Spectrecoin is pulling out all the stops in order to protect user identity through their integration of:
At its core, Spectre’s dual coin system sanctions four fundamental types of privacy and anonymity transactions, XSPEC > XSPEC, XSPEC > SPECTRE, SPECTRE > SPECTRE, and SPECTRE > XSPEC, providing a plethora of transaction options for every type of user.
And finally, if you’re looking for the TLDR (too long, didn’t read), Spectrecoin notes the best way to understand SPECTRE is to think of Bitcoin + Proof-of-Stake.v3 + anonymous transactions (similar to Monero) + Tor (for IP obfuscation).

Why You Should Keep an Eye On XSPEC

Unlike several other privacy coins which merely provide a Tor proxy—availing users to potential malicious exit nodes—Spectrecoin is fully integrated with Tor, a reliable and tested network providing one of the largest pools of IP addresses for confidentiality and untraceability.
Coupled with staking, set at a 5% minimum per year, Spectrecoin offers a unique proposition (the only one in blockchain) for users looking to earn rewards while remaining anonymous by staking anonymous coins while generating more, fresh anonymous ones.
Furthermore, for those looking for affirmation of Spectrecoin’s commitment to anonymity, not even the developers know each other’s real names—something that would have made walking away from a lacklustre ICO (which only raised 16 BTC at $600/700 per BTC) all too easy.
Spectre has emphasized organic growth without an excessive and aggressive marketing push, opting instead for a working product and timely improvements to meet the ever-changing privacy arms race. And, with their funding gap set around £19,000, users can take solace in knowing the project isn’t an outright cash grab asking for millions to further tenuous goodwill—like far too many projects in the cryptosphere.
At time of writing, XSPEC is listed on CoinMarketcap at US$0.41 or 5,970 Satoshis.
Finally, if you’re wondering how Spectrecoin stacks up to other privacy coins, such as Monero, PIVX, and Zcash, check out this comparison chart.

2. FundRequest ($FND) – $1 Million

What is FundRequest?

In an age where open source software is an integral component for institutional, government, and nonprofit function and growth, there unfortunately remains a hindering factor—a cohesive, transparent, and styled request and transaction flow.
Cue FundRequest, a decentralized marketplace for open source collaboration and catalyst for global open source sharing and circulation, empowering organizations, government, and other entities to:
Need to brush up on what exactly ‘open source’ means? The Open Source Initiative describes the concept of ‘open source’ as a tool which “enables a development method for software that harnesses the power of distributed peer review and transparency of process.”
For example, a requesting organization (referred to as the funder) will allot set funds—stored in a smart contract (i.e., escrow)—in order to tackle an open source issue, which is then picked up and solved by a developer (the solver). In order to eliminate malicious behavior, FundRequest requires solvers to “have skin in the game,” by staking proportional valued funds, all released and claimed once the issue is solved.
Simply put, FundRequest is the go-to facilitating and incentivization platform (similar to Airbnb and Uber) for funding, claiming, and rewarding open source commits and contributions, leading to an enriched and more collaborative open source ecosystem.

Why You Should Keep an Eye On FND

With an estimated US$60 billion-plus in savings per year for organizations and institutions, thanks to open-source software and technology adoption, FundRequest is set to act as the glue which connects all dispersed and integral parts and actors. Traditional software, prohibitive costs, and predatory vendor practices are proving not to be conducive towards maximal technological growth and development, as most people and organizations just simply can’t afford or maintain it.
Plus, with a clear push by both private and public sectors to leverage community-based software for development and distribution over the last decade, it’s expanding at rapid pace. In 2018, it’s approximated over 50% of European and North American companies utilize open source software for “crucial applications,” along with over 50% of American government organizations.
This is no small industry.
GitHub alone boasts over 24 million users (more than 8 times their user base five years ago), and it’s estimated that in the EU and United States combined, there’s over 160 million persons working as freelancers and independent contractors in what’s known as the “gig economy.” And that’s just the tip of the iceberg, with over 60% of online gig economy workers accounted for in Asia.
As of August 1st, FND’s price sits at right around US$0.03 or 472 Satoshis.
Finally, for open source projects and ERC-20 token projects looking to increase development capacity, consider checking out FundRequest for potential partnerships. Already in their short tenure, FundRequest has partnered with:

3. COSS ($COSS) – $7.7 Million

What is COSS?

Redefining convenience, simplicity, and compatibility, and short for the “Crypto One-Stop Solution’ exchange and platform, COSS is the native token and liquidity attraction tool of the Singapore-based exchange, boasting some of the most popular altcoins on the market while enabling users to receive weekly payouts in “dust” for all traded tokens.
Specifically, COSS is looking to provide more than just a simple, fast, and secure cryptocurrency trading exchange—they’re building a borderless, digital economical system to bring cryptocurrencies to the masses via:
Ultimately, COSS is looking to shake up the cryptocurrency exchange ecosystem through improved user experience, heightened product and feature functions, and a comprehensive foundation for employers, startups, companies, and traders to build towards a more accessible and mainstream cooperative blockchain community.

Why You Should Keep an Eye on COSS

With the rapid and gargantuan successes enjoyed by both Kucoin and Binance in 2018, crypto exchanges employing user-friendly token incentivization models are becoming a go-to for users looking to generate passive income while diversifying their crypto portfolio.
However, unlike other cryptocurrency exchanges which have lowered their daily fee splits to nominal amounts, COSS has stayed true towards user rewards, keeping their daily percentage at 50%—paying out the respective dividends via a decentralized autonomous organization, ultimately guaranteeing an immutable percentage.
In order to stay competitive in the present-day blockchain ecosystem, COSS’s whitepaper notes a minimum of 3-5 new features implemented per quarter. In the past several months, below are just several of their most notable achievements:
And, if you’re looking to know what COSS’s endgame here is, their goal is to shift completely towards a decentralized autonomous organization (DAO) in the future, where governance and decision making is outlined in code and run by a peer-to-peer network.
Currently, COSS’s price is listed at US$0.06 or 935 Satoshis on Coinmarketcap.
Finally, if you’re curious about COSS’s fee sharing, check out the COSS fee share calculator, which provides an accurate picture of your monthly exchange fee earnings relative to the amount of COSS owned. One Reddit user recently posted, and provided a screenshot, showing the COSS annual dividends to be at nearly 10% per year.

4. Lamden ($TAU) – $6.9 Million

What is Lamden?

Named after the Sherpa language word meaning “to guide,” Lamden is staying true to its name by easing the creation and deployment of dapps and custom blockchains.
At its core, Lamden is providing a suite of developer tools mimicking “modern development processes in such tech stacks as Node.js or Python.” Simply put, Lamden is supplying the building blocks for experienced and amateur blockchain developers alike, enabling organizations and enterprise to skirt the energy and time costs of hiring and training expensive blockchain developers—ultimately speeding up efficiency and reducing overhead costs.
Lamden is broken up into three fundamental sections, which all are in furtherance of project depth and the deployment of hyperfast blockchains for developers to not only experiment with, but test and deploy across other blockchain systems and platforms:
Furthermore, Lamden supports the Ethereum network and Bitcoin-based blockchains at present, and boasts zero transaction fees and free chain-to-chain payments in exchange for chain allocation a specific amount of bandwidth for confirming payment channel transactions—meaning that its users are able to transact for free as a result of corporate entities bearing the network load and processing.

Why You Should Keep an Eye On TAU

Having released their ‘Cilantro’ testnet alpha in February 2018, Lamden has since hit the ground running, rolling out their first version of Clove soon after and tackling the necessary tune-ups and improvements in preparation of their mainnet launch in Q4 2018. Lamden’s mainnet is set to utilize a unique combination of Delegated Proof-of-Stake (DPoS) and the BFT Protocol, and will scale to process nearly 10,000 transactions per second.
Moreover, in April 2018, Lamden announced the creation of LamDEX, their own decentralized cryptocurrency exchange and platform, where users will be able to stake their TAU—the native token of the Lamden platform—to act as a market maker, allowing for a cohesive back and forth across the TAU pair at prices faintly above and below market cost, ultimately generating rewards.
With a rather daunting and tedious task ahead for anyone looking to utilize and incorporate existing smart contracts—which involves the manual searching for such on GitHub (a general repository website)—Lamden is truly adding value to blockchain and application development through their smart contract repository. Unlike GitHub, Lamden supports dependencies, versioning, and security, all essential elements for a quality package manager.
Doing so adds not only convenience, but practicality to smart contract packages and implementation, and stands to save enterprise and organizations both exorbitant developer costs and time.
If you’d like to learn more about Lamden’s developer tool suite, check out this complete overview from their blog.
At the time of writing, Lamden’s price according to Coinmarketcap is US$0.04 or 699 Satoshis.
To get a better picture of Lamden and their blockchain development tools ecosystem, check out this explanatory YouTube video from their channel.
Final Thoughts
Risk is inevitable when investing in crypto and blockchain projects. However, as long as you are cognizantly defining parameters for absorbing such risk, then diversifying your portfolio with smaller capped projects can be an effective way to realize value.
Whether you’re looking for a user-friendly exchange to purchase crypto directly with fiat from (and earn dividends for loyalty) or wanting to execute anonymous and secure transactions with a P2P coin, the aforementioned projects are all bringing value to the crypto sphere through their overhaul of ineffective traditional mechanisms and institutions.
Make sure to stay calm and collected during this bear market, associate yourself with quality projects that you think are bringing actual value to severely flawed industries, and remember, having a little gamble in you never hurts (as long as it’s properly accounted for).
