In fact there are some investment altcoins outside Bitcoin that I predict its value will skyrocket in 2018. Ethereum is the third largest coin in the world after Bitcoin and Ripple. Initially Ethereum is able to sit in the second position until the end of December yesterday. Unfortunately Ripple managed to head the position Ethereum. In addition there are also Litecoin which I predicted as the best altcoin besides Ethereum and Riple. But for some reason until now I am more interested in Ethereum, my mind is always focused on Ethereum and I really believe Ethereum is the best altcoin of all time.
