I will pick Ripple to give me 3x or more by the end of the year. Other cryptos I believe are worth to hold are Ethereum, Tron, Basic Attention Token and Stellar.
one more, believe in a BNB coin because you can see the growth of the BNB coin market now very fast. I am sure the BNB will continue to grow until the end of this year. if you have it you can party early in the year.
