Hostility toward a community in which the target currency is particularly popular.

If you had a strong interest in Ethereum (for example), then I think you’d want to avoid the wholesale destruction of Bitcoin. If the biggest crypto currency fails, it’ll probably send shockwaves through out the entire crypto currency market.

Mind you, I say this as a crypto currency outsider.

That's true as long as cryptocurrency itself is seen as fringe; it's less true if cryptocurrency becomes generally accepted.

Of course, a nation-state or other actor interested in preserving the role of fiat and keeping cryptocurrency on the fringes is also a possibility.
