No banks have paid Bitcoin's users to use Bitcoin and not BCH. The "shill" accusation is a "copium" assertion by scammers to make themselves feel less stupid because nobody wants to transact on their worthless, insecure, incompatible, centrally-controlled hard-fork blockchain. If it were true, CashDragon (npub1erp…s9c5) would have shown receipts from me being paid.
But he's a liar and a scammer, just like Roger Ver and Craig Wright.
