Ethereum is the second most popular cryptocurrency after bitcoin, which is a great success considering the pioneering status of BTC. It is worth more than 50% of all bitcoins in the world.
The distinctive feature of Ethereum is the smart contract functionality. It helps to provide additional security and to reduce transaction costs. Stored in the Ethereum blockchain, smart contracts are the exchange mechanisms that can carry out the direct transaction of value between untrusted agents. This technology is one of the reasons behind Ethereum’s success.
Ethereum is well-known for volatility spikes. On 24 June 2017, the currency briefly crashed from $319 to 10 cents only to rebound later that day.
