As a retailer why would you accept payment in a currency with this sort of daily volatility of 10%, which doesn’t even have instant confirmation (!!??), has slow transactions, no rollback, no fraud detection or insurance and has high fees?

As a customer why would you make payment in a currency with high fees, poor ux, slow transactions and just enough anonymity to make it perfect for scammers?

As a payment processor why would you touch this currency with a barge-pole given the above problems?

Cryptocurrency isn’t the future of currency or payments, and bitcoin in particular is solving the wrong problems, badly.
