2018 is the year to buy. The bear market which we all were asking for in December 2017 is here. But all i am seeing is people complaining.
Go for privacy coins. They would be huge someday.
DeepOnion (Huge room for growth since its low cap) , XMR (Safe bet, small room for growth), Zcash(Safe bet)
Also non privacy coins like Nano, EOS and ETH are good buys.
