A cryptocurrency is a medium of exchange like normal currencies such as USD, but designed for the purpose of exchanging digital information through a process made possible by certain principles cryptography. Cryptography is used to secure the transactions and to control the creation of new coins. The first cryptocurrency to be created was Bitcoin back in 2009. Today there are hundreds of other cryptocurrencies, often referred to as Altcoins.
In 1998, Wei Dai published a description of “b-money”, an anonymous, distributed electronic cash system. Shortly thereafter, Nick Szabo created “bit gold”. Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.
Ethereum has recently faced some scaling issues as the number of companies launching an “Initial Coin Offering” (ICO) has boomed. The network has been bogged down for many hours or even days at a time due to a handful of popular projects launching their own ICO to raise funds.
One of the things that sets the New Economy Movement (NEM) apart is its “Proof of Importance” (PoI) algorithm. Unlike PoW, which requires miners to use significant processing power to get new coins, or PoS, which requires users to already own a certain amount of coins in order to get new ones, PoI actually encourages users to spend their coins. The PoI algorithm tracks a user’s transactions to determine how important that user is to the overall NEM economy.
Cryptocurrencies have been compared to ponzi schemes, pyramid schemes and economic bubbles, such as housing market bubbles. Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were “nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it”, and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999). In October 2017, BlackRock CEO Larry Fink called bitcoin an ‘index of money laundering’. “Bitcoin just shows you how much demand for money laundering there is in the world,” he said.
Bitcoin Gold is a recent fork of the Bitcoin blockchain, primarily aimed at decentralizing Bitcoin mining again. Bitcoin was initially mined using CPUs. Then, miners moved to GPUs, and finally to application-specific integrated circuit (ASIC) chips.
Dash (originally known as Darkcoin) is a more secretive version of Bitcoin. Dash offers more anonymity as it works on a decentralized mastercode network that makes transactions almost untraceably. Launched in January 2014, Dash experienced an increasing fan following in a short span of time. This cryptocurrency was created and developed by Evan Duffield and can be mined using a CPU or GPU. In March 2015, ‘Darkcoin’ was rebranded to Dash, which stands for Digital Cash and operates under the ticker – DASH. The rebranding didn’t change any of its technological features such as Darksend, InstantX. (Related reading, see: Top Alternative Investments for Retirement)
Bitcoins are not issued, endorsed, or regulated by any central bank. Instead, they are created through a computer-generated process known as mining. In addition to being a cryptocurrency unrelated to any government, Bitcoin is also necessarily a peer-to-peer payment system since it does not exist in any physical form and must be exchanged online. As such, it offers a convenient way to conduct cross-border transactions with no exchange rate fees. It also allows users to remain anonymous. (Related reading The Risks Of Buying Bitcoin)

Even legitimate exchanges may not have adequate security in place. Last month, a prominent South Korean exchange was forced to shut down after being raided by hackers who stole the cryptocurrencies. In such cases there is very little authorities can do to recover the funds.
Blockchain’s conceptual framework and underlying code is useful for a variety of financial processes because of the potential it has to give companies a secure, digital alternative to banking processes that are typically bureaucratic, time-consuming, paper-heavy, and expensive.
Notably, all of those systems utilized a Trusted Third Party approach, meaning that the companies behind them verified and facilitated the transactions. Due to the failures of these companies, the creation of a digital cash system was seen as a lost cause for a long while.
Every transaction is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the amount of coins transferred. The transaction also needs to be signed off by the sender with their private key. All of this is just basic cryptography. Eventually, the transaction is broadcasted in the network, but it needs to be confirmed first.
Who is in charge of Bitcoin? The point of the currency is that it is decentralized, but there are legalities that differ in every country. Law enforcement and tax authorities are concerned about the use of this cryptocurrency because of its anonymity and the ease of using it for money laundering and other illegal activities. Bitcoin was the prime currency on Silk Road, which was used to sell illegal goods, including drugs. It was shut down in 2013 by the FBI.
Even though his friends and most of his relatives questioned his enthusiasm, Groce didn’t hide his confidence. He liked to wear a T-shirt he designed that had the words “Bitcoin Millionaire” emblazoned in gold on the chest. He admitted that people made fun of him for it. “My fiancée keeps saying she’d rather I was just a regular old millionaire,” he said. “But maybe I will be someday, if these rigs keep working for me.” ♦
