for me only those coin that are listed as a top 10 cyrpto currency through coinmarketcap has a future like bitcoin. wherien no other than because they will not be listed on that level or should i say rank if they're not trusted and not a very promising project..  To be honest cmc is a very good site as well mate so when it comes choosing good project,  I highly recommend to always rely on it instead of looking for some sort of site that listing crypto currency, because isn't safe due to some fake volumes and etc when it comes a projects.. Remember that mate.
