because the "anonymous" hashpower is @BITMAINtech that's why. @JihanWu is undermining the value of his large BCH hodlings by centralising it

for example if @BITMAINtech were asked to freeze it, mechanically they could because they're majority of the hash rate.

being in central control of a coin is risky for you, and makes the coin less valuable because people understand that risk of freeze.

for BCH that may be ok as a medium security slightly higher scale, on-chain only retail coin, and his choice. but for Bitcoin that is NOT ok
