Ethereum (ETH) is more than just a currency – it’s like one giant computer housing many computers around the globe. Ethereum can respond to sophisticated requests. Its ability to store revolutionary computer programs, known as smart contracts, gives Ethereum an edge over Bitcoin and has attracted attention from banks around the world. This, among other factors, has led to a jump of almost 10,000% in 2017!
All of those factors make mining cryptocurrencies an extremely competitive arms race that rewards early adopters. However, depending on where you live, profits made from mining can be subject to taxation and Money Transmitting regulations. In the US, the FinCEN has issued a guidance, according to which mining of cryptocurrencies and exchanging them for flat currencies may be considered money transmitting. This means that miners might need to comply with special laws and regulations dealing with this type of activities.
In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash. Later, in 1995, he implemented it through Digicash, an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.
