Both of them will last long but in order to survive they both need to evolve and innovate . As of today there are 2 types blockchain the permissionless public blockchain and permission private blockcchain . Bitcoin belong to public permissionless blockcchain where anyone can join the network without any permission from the majority node. Private blockchain on the other hand are used for businesses and enterprise one of the example of a permission private blockchain is the Hyperledger. Bitcoin will survive but without evolving and less innovation then bitcoin can then be a boring blockchain in the long run.
