In my opinion a lot of coins will survive, the market is becoming bigger and bigger so there will be more coins in time. Even these cryptos which are brand new have opportunity for economic and social development like FuturoCoin. The ideas are so innovative, e.g. FTO updated FuturoCoin masternode system gives their users opportunities to make a profit. Also, cryptos affect other fields, not only market connected with money
A lot means majority of the total? I think, it's not possible.
The market especially in altcoins is full of scam coins and tokens, only few of the total coins created will succeed.
The project that has a chance to succeed are those who are traded in good exchanges now, with volume and liquidity, it will make the team work hard as they are seeing they have the potential to grow the project with the support of investors.
If we check the entire market, majority of the coins still has not exchange, some are just trading in decentralized exchange but with low volume.
