Are you not supposed to be neutral on this?
When giving information (such as how to take your coins to a safe wallet and control both chains, or how a chain split occurs), theymos should be neutral and he's done that well. But this is just discussing the future prospects of BCH, so it's fair enough. At least the wording is tentative - some people on the forum have irritated me by acting like they're 100% certain about exactly what will happen.
My thought is that BCH will be dumped for a few days or so, with a couple of dead cat bounces on the way. It will reach a moderately low price (let's say 0.01-0.05 BTC) and stay there for a long time. During that period, whales will be subtly accumulating it a bit at a time, and in about 2-3 years we'll have a crazy ETH-like pump with a lot of FUD that the old Bitcoin will fail completely.
The idea that it could overtake Bitcoin seems farfetched...but with a lot of hashpower behind it (Bitmain)
BITMAIN is not actually going to dedicate hashrate to it. At least not yet.
a major payment processor (Bitpay)
I don't see any actual merchants agreeing to take it though.
and support from large exchanges (Bitfinex, Kraken, Okcoin, Huobi, BTCC), I could see it gaining some traction.
Some of those exchanges have not actually agreed that they will trade it, just that they will credit it to their users' balances. Even if they did trade it, it wouldn't matter - these exchanges just need to rake in fees.
