I strongly disagree.
Just because Avalanche might be PoS, doesn't mean that BCH is not PoW. Avalanche is pre-consensus. Some sort of pre-consensus is needed for more efficient mempool
syncronization (which helps future scaling massively) and 0-conf security. Also, regarding dynamic block size, that is still very much on the table. BUs ineptitude has nothing to do
with it. BSVs trajectory is a dead end. They ignore fundamental scaling problems, and they still haven't demonstrated that their approach can someday to sustained GB blocks.
