I think at the end of 2020 only the fittest coins will survive the cryptocurrency market. By fit, I mean the most use cases such as Ethereum. There will be market leaders like Ethereum, Bitcoin and others. And along with them the coins which serve to a whole particular industry which have already accepted the coin for their use will survive and rebuild the whole crypto world.
any coin that will be potentially good at the end of 2020 we be able to predict and say whatever it is, but we will not be sure, because anything will happen inside crypto, because if i see now many altcoin that have good potential and could be growing rapidly for the future, so whatever will happen later, surely someone is wrong in their speculation in investing, so whatever our choices hopefully will be able to make us get big profits.
