Quite simply no, the majority will fail, I would expect 10-20 coins will eventually dominate and control the whole market.
of the many coins on the market, only the best will survive because we all know that not all coins have the same potential. it's just that every failure will be followed by something new, so Crypto will always develop with a variety of coins, from bad, pretty good and best.
so we don't need to worry too much because new projects will always appear.
