NG Zhang,creator of the first ASIC mining machine.
He definitely holds a lot of Bitcoin.
I think the creator of Bitcoin has the most Bitcoin in his wallet, and as we know, the creator of Bitcoin is Satoshi.
He had the most bitcoin if he did not forget her private key. I think he said it in here or someone wrote it that satoshi lost his private key. but I don't think about that now, because we know that had the most of bitcoin will not appear and no one knows who he is. maybe his a business man or ordinary man that trading her money and cycle it with bitcoin. no one knows. but I think he is the one or he can manipulate bitcoin price if he want it.
