My favorite coin is Ethereum, which has been revolutionary in recent years. It appeared only in 2016 (Creator Vitaly Buterin). During this time, it has managed to grow 1500 times. In 2017, it grew by 120 times.
Only in 2017, Ethereum began to take first place in the list of the most promising currencies of the future. According to rumors, this coin was purchased by the largest corporations in the world: Microsoft, Google, Apple.
I also really like ethereum, I hold some ETH as an investment. Its mission is clear and has a very potential platform. Moreover, eth occupies the second position in Coinmarketcap. Spread price is quite varied so we can use for taking profit.
