I will give an example.
Transactions in blockchain checked in within 10 minutes. For credit cards it is not. That's why from 5% to 10% of all "card" transaction canceled on the spot, and further proceedings will take a few more days. With blockchain retailer sales grow, as he will not have to cancel the transaction, and the Commission will be substantially lower. That's enough to make a significant impact on the industry. It is wonderful.
Yeah i agree with you, plus more if we want to use credit card then we should bother to come to the bank and sign on some paper with it we express our identity to the bank. in contrast to bitcoin, we only need to buy it by fiat we automatically have some bitcoin that can be used to buy something.
That's one reason is not yet capable of being used in direct transactions but as we know bitcoin is developing and upgrading the issues that user encounter and soon this problem will be fix.
