The top list in CMC are one of the coins have a future mostly bitcoin and etherium are have a big impact in crypto currency.
But if we ask of which new coins have a future Ill think no one knows of new coins are have a future, Because we always seen some new coins are becoming a shitcoins maybe the development of that coins are probably not maintain to the people belongs of that kind of coins.
to be honest, ethereum is currently the most highlighted coin. I say things like that, because when you see comments about promising and potential coins, ethereum will be there. Well, I also think so, so, I think Ethereum will have a very promising future when seen at this time.
