Yes of course it will. The only reason why there are so many coins out there is that where the money is. Huge amount.of money is being transacted here, that some people take advantage by trying to tokenize everything to earn money. But for sure blockchain will be very useful leaving only significant coins.
Blockchain will continue to be developed, because blockchain can be applied to all fields of business, not just cryptocurrency. Even people or companies that don't agree with bitcoin, still recognize the superiority of the blockchain and apply it to their business. Examples are Jack Ma, founder Ali Baba from China.
