Maybe bitcoin would slightly edges credit and debit card in the first world countries.
No maybe about it my friend Bitcoin is superior to credit and debit cards in every country worldwide, how much would that cost to send a wire transfer across the planet from Africa? Then how much to send a bitcoin payment.
Somehow development does need to be made to reduce the amount of time it takes for a transaction, this is a must and i hope they can do it because this is what is holding it back imho
Bitcoin is not built on debt which is my main reason i am here for as long as it is here.
