As we all know chain block technologies are the foundation of the cryptocurrency and chain block technologies can develop without the cryptocurrency.
Is this possible happen in the future? If so, how?
Without cryptocurrency I dont really see any use for blockchain. Blockchain is meant to run alongside cryptocurrencies and they are meant for cryptocurrency, without cryptocurrency there will be no use for blockchain unless maybe they will find something else to do with it, but I dont see any useful thing that they can create on the blockchain which is not cryptocurrencies like bitcoin.
