My pick is on electra! Its already on fire and going to be added on a new Exchange in january.
Im not sure on electra if price will hit big this year 2018. Im on ethereum as the best coin for all this surely will hit huge price by next year. I always look into this price and ofcourse those who hold will get huge earnings.
Ethereum is amazing but it can't actually make 100x or 1000x type of growth. We should look for something very cheap, maybe in the range of $0.1 and $1 so that they can initiate to make such growth on the exchanges.
