Cryptocurrencies

CryptocurrenciesThe attackers behind last month’s WannaCry ransomware were planning to extort $300 in Monero cryptocurrency to unlock encrypted files. Until this crisis, who had ever heard of Monero? How could you even buy Moneros to unlock your PC, if you wanted to take that chance? More people are probably aware of Bitcoin (BTC). The Visual Capitalist explains that Bitcoin is the original cryptocurrency, and its meteoric rise has made it a mainstay of conversation for investors, media, and technologists alike.

cryptocurrencyDespite its shady history, Bitcoin has spawned over 800 new markets and cryptocurrencies. While Bitcoin is the dominate cryptocurrency, with a market cap of $37.2 billion, the rest of the cryptocurrencies are worth even more, in combination they are worth nearly $40 billion. The leaders of the altcoin movement are:

Ethereum (ETH) launched in 2015, is the second largest by market capitalization. It is also quite different from Bitcoin. The Visual Capitalist explains that while Bitcoin is designed to be a payments protocol first, Ethereum is designed to work as a blockchain-based computing platform for developers to build and deploy decentralized applications, while also enabling smart contracts. The tokens used to power the network are called Ether, but they can also be traded online. At time of writing, Ethereum’s market capitalization is $15.4 billion.

Ripple logoRipple (XRP) is the native currency of the Ripple Protocol – a broader catch-all for an open-source, global exchange according to the Visual Capitalist. Ripple is aiming to be a settlement protocol for major banks, It’s already being used by banks such as Santander, Bank of America Merrill Lynch, UBS, and RBC. Ripple has a market cap of $10.9 billion.

Ethereum Classic (ETC) The Ethereum network actually split into two in 2016.The Visual Capitalist says it’s a complicated situation. You can read about the hack v. hack battle here. Ethereum Classic is based on the original Ethereum blockchain, and has a market capitalization of $1.4 billion.

Litecoin logoLitecoin (LTC) is one of the first altcoins, and it is nearly identical to Bitcoin after being “forked” in 2011. Litecoin aims to process blocks 4x faster than Bitcoin to speed up transaction confirmation time, though this creates several other challenges as well according to the Visual Capitalist. At time of writing, Litecoin’s market capitalization is worth $1.3 billion.

Monero (XMR) is an open-source, privacy-oriented cryptocurrency launched in April 2014. It is the result of a fork of the Bytecoin cryptocurrency According to CoinDesk, Monero is private by default, and it has achieved the widespread adoption of those interested in using cryptocurrencies to remain anonymous. Monero has a market capitalization of $6.2 million.

Coin Market Cap Monero chartThe price of Monero’s XMR has experienced significant volatility at times, climbing more than 1,300% since it began trading on CoinMarketCap. Since its start, the cryptocurrency has fluctuated between roughly $0.25 (in January 2015) and close to $60 (in May 2017).

Monero leverages ring signatures and stealth addresses to obscure the senders and recipients identity. Ring signatures combine or ‘mix’ a user’s account keys with public keys obtained from Monero’s blockchain to create a ‘ring’ of possible signers, meaning outside observers cannot link a signature to a specific user.

Monero logoOriginally, ring signatures obscured the senders and recipients involved in a Monero transaction without hiding the amount transferred. However, an update called RingCT implemented a new ring signature that concealed both the value of each transaction and the senders and recipients identities to make transaction tracking harder.

In addition to leveraging ring signatures, Monero also enhances anonymity through stealth addresses, which are randomly generated, one-time addresses created for each transaction on behalf of the recipient. With this feature, recipients publish a single address and transactions they receive go to separate, unique addresses. As a result, Monero transactions cannot be linked to the published address of the sender or recipient.

By providing a high level of anonymity, Monero offers fungibility, meaning that each individual unit of a currency can be substituted for another. Another way of putting this is that every coin has equal value.

Due to Monero’s untraceable nature, no two coins are distinguishable from one another, and they are both equal in the eyes of merchants. Without this level of fungibility, a vendor that accepts cryptocurrency might refuse a unit of one of these assets because of its past possibly illegal transaction history.

CoinDesk points out that Monero has enjoyed a steady increase in adoption since its release. This adaption seems to be led by Dark web marketplaces like AlphaBay and Oasis which have embraced it, reportedly due to popular demand.

For those who want to purchase Monero’s, to pay a ransom or for other reasons, can purchase them at an exchange. The Monero market operates like that of many other cryptocurrencies. Those interested in buying the cryptocurrency can get it through exchanges including Poloniex, Bitfinex and Kraken.

Bitfinex, offers XMR/USD and XMR/BTC exchanges along with deposits and withdrawals of Monero. Kraken offers the same options as Bitfinex as well as XMR/EUR.

Other cryptocurrencies in the altcoin universe include NEM, Dash, ByteCoin and Golem.

If the fraudsters who set off the WannaCry crisis were expecting to make a fortune in cryptocurrenncy, it didn’t work. Apparently there have only made approx. BTC 50.91735344 or just under $150,000 on 320 payments world-wide according to a twitter bot actual_ransom from @collinskeith which is watching the bitcoin wallets tied to the ransomware attack.

I dunno know – Until somehow cryptocurrencies break their implied link to illegal activities online, they will be relegated to the black market. 

The value of cryptocurrencies are really hard to pin down because no one really knows how much they should be worth. Unlike a company there are no assets or revenues that can be used to assess a predictable valuation. So they are subject to wide swings in valuations because they operate without any tangible value behind it.

The underlying technology of blockchain seems to have a brighter future
