In every beginning it`s like that, this wave of new crypto currencies, coins and tokens built on some platform will not last forever. Something like crystallization, we will see bad ones falling off, and good ones will make a beautiful stone. Money is just a medium of exchange, before couple thousands years money was in the form of small knives and spades, we have money in the form of gold and silver, now we have paper bills and from recently credit cards, crypto currencies are the next step in evolution. All of them have some similarities, pros and cons, but each of them is special for something. Some crypto assets have real usage already and high value, don`t believe in every video from youtube.
