Of course, there are still a lot of altcoins that are still productive but not all altcoins have good potential, many new altcoins are popping up, in my opinion it would be better if we buy coins that are on the best list because it will definitely give us good profits in the future if we invest it now
There is a huge number of altcoins in the market, we have to be choosy when investing.
Based on the articles I read about ICO, majority of the project are just scams and they are called altcoins when listen in the market.
So, be careful, be smart in choosing so that opportunity to make money in altcoins will come into reality.
