Many altcoins have a potential and productive in the market. You just need to choose the best for you. In the future this will be more and more. Now the people tends to invest in altcoin than any other business. becasuse they know about the future.
yes, now many Altcoins have potential in the future, I think only ALTcoin is good and has great support that will survive in the future if for long-term investments I recommend choosing trusted Altcoin like ETH or NEO.
the selection of altcoin determine also our profit income, so I also argue that the same select altcoin which does the obvious progress and development in the market, as well as etherium. don't despair, there will surely be the most beautiful moment of the time came to pay the current disappointment.
