Bitmain switches all it's miners over to bch and starts buying bch with the IPO money, the momentum would shift dramatically, some Bitcoin core die hard supporters might go down with the ship, but the vast majority of crypto investors don't treat the 2017 scaling war like a religion, they'll just follow the herd when it's obvious the flippening is first possible, then probable, then actually happening
I interpret this recent bitmain document release very differently, it shows bitmain will likely have a war chest of all three resources they need to achieve their goal sometime soonish; bch reserves, IPO cash, miners ... I think bitmain is in a very powerful position now, I see dudes like Jimmy Song trying to spin bitmain as having failed at a peg in his videos, but imo bitmain will soon have everything they need to manipulate the price to something close to parity, and even if it's not popular at first, fear will take over enough traders already suffering big losses from the bear market, and bingo, the herd moves to bch.
The bitmain finances show they are serious, there's just not enough financial backing on the other side with the same level of skin in the game, the big traders just want to make money, they're not emotionally attached like zealots on this forum, they'll move their money to the Bitcoin version that has price support and mining, and the bounty bitmain will reap from the accumulated bch could make them a trillion dollar company sooner than many think, a powerful incentive to go all in for the flippening.
Fascinating times! Once it starts the early movers make money when they convert at the expense of those who delay, so once the momentum starts it could be quick!
bitmain have shot their bolt and thrown the kitchen sink and still failed and that was at a point where holders had free BCH so, as the advocates maintained at the time, they had 'nothing to lose' if it flipped.
now it's over a year since the fork and there'll be millions of people who don't have any of it and have no interest in owning it.
there is no one with any credibility involved with BCH. no financial institution has made any mention of BCH whatsoever. it gets virtually no press.
it was a one time shot at usurping bitcoin. it failed. there won't be another. that doesn't mean there won't be big ass pumps in future but its place in the firmament is set. if they let go of their obsession of 'becoming' bitcoin and concentrated on being a great coin they'll get alot further.
