Also unlike PayPal a transaction takes a few hours instead of a few seconds. Wait, that's not a good thing...

Platform? Bitcoin is bitcoin, either you use a different crypto (in which case we're no longer talking about bitcoin) or you're using some fluff on top (in which case we're also no longer talking about bitcoin).

I think he meant how many confirmations they want, 0 confirmations is instant, also unlike paypal you won't get charge-backed.
