I think blockchain as well as crypto are here to stay.
However, Bitcoin is essentially a useless coin. It did a great job in introducing a lot of us in to the crypto world, but faster crypto's that serve a double purpose (i.e. steem(social/crypto), eth(contract/crypto), etc etc) are where I'd focus for the future.
Defo, but for now, Bitcoin is the face of crypto, if you like. So, in essense, the "brand" will sell itself by name alone. And it will stay like this for a very long time until the rest of the world catches up to what we already know.
