Bitcoin effectively froze when Blockstream decided against increasing block size. The way I see it, bitcoin only stands as the flag-bearer, as (much like bitcoin cash) the transactions are too slow and still cost money. As the ecosystems grow and stabilize I imagine we'll be having some of the more full-featured, specialized cryptos carve out a spot within their specific domains (Dash or Raiblocks effectively taking over the "currency" use case for example).

I agree that the environment between the bitcoin and bitcoin cash communities is extremely toxic but I downplay how much that matters for a simple reason: bitcoin has been steadily losing dominance in the space and bitcoin cash is completely useless feature-wise, when compared newer-gen cryptos and even older ones like Litecoin. So sure, it's a nasty environment but it's one that I suspect we can just let die quietly in the corner.
