Yes there’s definitely value in Bitcoins hash power and underlying technology. But the code is open source and easy to copy. There’s a team behind it that is definitely worth something for Bitcoin but they could certainly work on any blockchain (especially if it’s a Bitcoin fork).

I think forks are definitely the biggest concern for Bitcoin. I think most longterm holders arent realizing how big of a threat it is.

Bitcoin Cash is still around and can probably stay around for a long time reusing Cores work. Other forks will be less friendly and won’t preserve Bitcoins transaction history.
