what happens if bitcoin builds a bank just like a bank with a headquarters, savings account management and also makes a bitcoin account card ??
Bitcoin would become centralized, fiat currency. We could call it the Dollar?
Why would a single bitcoin bank, a centralized bank, be a good idea? Honest question. All the features you speak of exist in the crypto currency industry, why would we limit the industry to just one provider? Doing so stifles competition, which hurts consumers.
Some people aren't cut out for Bitcoin, maybe you're one of those people.
