actually there are thousands of altcoins in this market are useless and very few of them are really success in the future. however, if we can hold as much as altcoins we can in the future and just need 1 altcoin special, we really can turn the entire asset become richer in just a short time.
only one coin? what coins? many altcoins on the market that help market growth become increasingly crowded. if you only focus on one asset that you think can bring you big benefits, the probability of that happening is 50%. try to share with other altcoins, even though many don't have value, but at least those on the market are those who are traded by their own community.
