future of bitcoin is paying for everything with bitcoins, everyday grocery etc
I don't see many people paying with it through a drive through. 10 min wait could stall fast food lol
I wish people would stop bringing this up as if it's a problem. You don't have to wait ten minutes. Have you ever actually sent bitcoin?
Why do u think that u dont need to wait 10 min ? Unless u wait, there remains a chance of double spending ...is no it ?
There is always the chance of a double spend attack, even after 6 confirmations (via a 51% attack).
Once a TX has been propagated throughout the network nodes will consider the inputs as spend and will reject any TXs that contain the same inputs even when the TX is 0/unconfirmed. The only way to double spend would be to include a block in the blockchain that spends at least one of the same inputs. With small purchases like fast food this would generally not be economical.
