There's a saying in China, that roughly translated amounts to "If you can cheat, then cheat."

I don't trust Bitmain at all. They could tell us they "sold out" of their inventory, and for all we know they're lying around in their warehouse, or mining for Jihan instead. The slow bleed of Bitmain has accelerated, and its very possible they could be in bankruptcy by the end of this year. They're taking a huge hit on defending BCash, which by the way they've pulled back on, they have less than 14% of the hashrate under Antpool. No doubt powering down in places where it isn't profitable, and switching to Bitcoin to make up for some of their losses.

Marginal miners fall out all the time, its part of the process. The recent hashrate decline took back 6 months of added capacity, but it isn't a nightmare scenario. Bitcoin is still safe, still not about to be 51%-ed by anyone any time soon. Its the faltering alts and altforks that have to worry during a Bear market.

Several coins have been 51% attacked, and successfully too I might add. Capital misallocation always gets rewarded with big losses. Look at Coinbase, now to be known as shitCoinbase, because they're desperately trying to add more tokens to boost their revenue.

Watching BCash and shitCoinbase implode will be pretty hilarious. And they deserve every bit of it.
