NEO and OMG seems to be quite promising.
I will hold Zilliqa , Nucleus vision and Travelflex along with them.
Going to participate in Egretia ICO and will hold them too for long terms.
ETH, NEO, OMG, QTUM and WAVES are great ones to hold for 2-3 year long period. At the end, they might result in excessively high prices. They will gain momentum from the markets clearly. They all will be huge in the future.
