Bitmain shouldn't have 8/10 in ehtics. They abuse cgminer's software license, caused a hardfork by not checking blocks they mine on top on and lied about Antpool beeing a p2pool pool (not related to their hardware but same company).
Why are you talking about Bitmain DC >10% ?
AntPool is a Pool for Bitmain's customer. Do we know smth about Bitmain selfish DC?
They don't really advertise. Only picture I have seen is Yoshi holding a sign when they thought about selling a whole center.
So I don't think we know unless someone has some inside info.
A good portion of Bitmain's hardware is on AntPool. The Yoshi sign was an S2 farm being sold on behalf of a customer, it wasn't Bitmain's.
So Bitmain doesn't have huge self mining, right?
It does have huge self mining.
"Huge" is a relative concept
Somebody will say BW is a huge player, somebody Ghash, somebody Kano
Which is why the FF rating isn't used any more. If you have a farm of any meaningful size, you get an F rating.
