Anybody who does a normal transaction with normal fees gets confirmed quickly.
There was a time when these were not 'normal fees':
OUCH. So BTC fees are thousands of times higher than BCC. And BTC has a huge full mempool that Segwit lock-in hasn't helped AT ALL.
At this point we can objectively say that BCH is superior technology when compared to BTC. While BTC has name recognition, big investment, a cult of lemming followers, and lots of market inertia, there is really nothing else going for it. Mainstream hodlers aren't technically sophisticated enough to understand the deficiencies of Segwit, full blocks, high fees, and the coming death spiral. Meanwhile, alts pump and ICOs continue unfettered. BTC/fiat continues to skyrocket, so the crunch will be extra painful.
I think the death spiral thing is really scaring the Segwits, so much so that they have to quickly yell and scream about BCH being in a death spiral, despite no evidence of that.
I've read the death spiral argument over and I believe it's sound. Basically if BTC loses hashrate quickly, it grinds to a halt and no one can transact. The already-full mempool just goes astronomical and no blocks are mined. Since BTC has been so slow anyway, if the majority of hashing goes to BCH for even a week, BTC is in serious trouble. If BTC really does fork again, at least one of the BTC forks (probably the 1MB fork) will certainly become useless and die.
