Apparently the Bitcoin subreddits are talking about this as a huge focus and it isn't being brought up here. Rumor has it that Bitmain has threatened a 51% attack if the BU fork happens, this has now started for a push for a new algorithm debate.I haven't found all the information but this seems like it could be the worst outcome, split coin and changed algorithm could only devalue Bitcoin more and more.
Pretty sure this is FUD.
I doubt miners would waste their resources on such a convoluted scheme (attack a chain and then turn around and mine on the opposite chain), especially since they need all the resources they can get to show strong hashpower majority on the new chain.
Yeah, 51% attacking costs much energy, power and time, it is not worth to try this non-sense on impair bitcoin. Future fork will be a long fight, not easy to make the consensus on SW or BU.
