There are a lot of promising coins. I think that as many people expect and forecast, this year can be the year of NAS, ICX, POWR.
This year and the next few years will be a lot of ICO, thus making the competition of coins and tokens is very tight, this is what makes dev. need to make a good development so that investors do not hesitate to put the money. Some big coins will survive for a long time such as ETH, NEO, XRP and so on.
