I thought carefully, and I feel that it's quite difficult for Alpha on BC.

Big Brother's avatar will have to be changed sooner or later. If Alpha is on BC and there's a surge that attracts more buyers, it will be very difficult for Big Brother to change his avatar later. Changing the avatar will instantly lead to a drop, and he will get criticized again.

It's better to handle it coldly like this, not mentioning Alpha, waiting until there are fewer people and no one is playing, and then change the avatar.
