From the consumer perspective CC transactions are effectively instant, at least for the strip transaction. Even introducing the short delay that the chips involve has been very unpopular. (Why they went with chip+sig is clearly some form of non-security motivation.)

The solution to bitcoin, ironically, would be bitcoin+signature. The signature is forming a contract, a promise to pay. This is different from waiting for /an/ actual payment to clear.

From my limited use of Bitcoin, the merchants only required the transaction to be broadcast They didn't care if it had 0 or 1 or 100 confirmations. They only cared that it was broadcast. Which makes sense. Considering they all apparently only did 4 Bitcoin transactions a month if not less. (2 cafes and a pub)

This is completely different to how online stores have processed my Bitcoin. Usually waiting for 1-2 confirmations before shipping (Trezor is my example here)
