- Hello, I would like to order a milkshake and a cheeseburger.
+ Sure thing, sir. Price is will be 0.04 BTC
- (Pulls out his phone and sends the bitcoin)
- (1 hour later)
- Where is my food?
+ I'm sorry sir, bitcoin network is currently very slow. The chef said if there is no three confirmation, there is no food.
- (Internal screaming)
Oh so when your credit card takes a month to confirm they hold onto the food until it officially confirms? Your logic is flawed. The only way to spend and have it confirm instantly is cash.
Thats why you can send and make your transaction be faster paying a bigger ammount from fee, or you can use the bitcoin debit card as i know it does make the transactions like a normal debit card, soo this isnt an issue at all.
I think using bitcoin debit card not practical and will feel the same as the ATM, way more practical is facility login with all the wallet available then there is a confirmation SMS or email. I think that way is more safer and practical than no matter where should bring ATM card.
