I believe that most of the Altcoins will survive. The question is put as if only a few will survive and it is necessary to decide who these lucky alts are. Surely they were not created in order to perish. Yes, each altcoin has its own team, its level of capitalization and technical support. It is clear that not all will reach the finish line at least in the next five years. However, I believe this will be a unit, not a mass phenomenon.
