There is lots of good potential coins snovio, electroneum , Trx, dimcoin will reach atleast good growth in next couple of months for sure . Even you can bet for doge coin and dcn if your time is right you may get huge profit.
Not every coin has great potential. If coin has some 3 billions marketcap it's just big risk without big reward part. Low marketcap coins can make big returns after gaining some popularity, big marketcap coins already got all attention from media and can't make easy x100.
