But first, let me tell you the coins that I have already invested into-
ETH, ETC, STRAT, DASH, XRP, SC, DOGE, LTC, BURST, ZEC, STEEM, NXT, BCN, LSK, ANS, AMP, BTS, XZC, CLAM, XMR, WAVES
You are already holding one of the most prespective coins at the moment. You can check maybe some coins such as XtraBytes or Verge. They are not so good, but will deffinetly rise a little bit.
