I'm scared about the idea that Bitmain is holding a huge amount of BTC which they mined in the early years of ASIC mining equipment and that they will sell all their BTC at once, causing the most fatal crash in the complete history of BTC.
imho if they decide to sell, they won't sell it all at once. They would sell it few at a time over six months period. I'm not saying that' exactly how they would do it but that would be the smart way to do it unless they wanna lose money.
