Since hardly anyone uses Bitcoin for live transactions, sure. (I
managed to buy two cups of coffee, quite a while ago.) On the other
hand, if it became at all popular for on-the-spot transactions and
word got around that you could get away with double spending, the
result would be predictable. Of course, this isn't a problem for mail
order purchases of illegal drugs.

Aw, come on. Credit card transactions typically authorize in a few
seconds and merchants get the money overnight. 60-90 days was for
international transactions 30 years ago. If you're comparing it to
something like selling stuff on Amazon, that's Amazon holding back
the funds, not the credit card company.

Right, it's a prototype.
