Bitcoin will *never* scale up to Visa or Mastercard and anyone who thinks so is really "kidding themselves".
In the world of "remittance" Bitcoin can be king but in the world of general transactions it is never going to get there.
When will you guys realise that "normal people" actually *want* reversible transactions and the safety of their banks. They are *never* going to want to lose their money to scammers who want to take advantage of irreversible payments.
It is so funny that Bitcoin fanatics just seem to forget all about "customers" (probably because most of them are scammers trying to steal their customers money).
