What I was going for was: if it's a standard contractor-like payment, what paperwork do you save by using cryptocurrency?
So that paperwork is one of the hassles that we save. Sending payment is one-click. Then it's done and there's no possible undoing.
Bank payments can be denied, reversed, routed strangely, delayed or something else. Bitcoin is more binary; either it works instantly or it fails and you know it. There's not so much doubt about it. Though high transaction fees for a few weeks last year did introduce more uncertainty, that is true.
Anecdote: Out of hundreds of small monthly salary payments I've sent out, I've only once had a big problem. What happened there was that the payee said she hadn't got it, but the blockchain said it was sent and confirmed.
Of course I certainly trust the blockchain to tell me the truth. More than I trust a bank. Who wouldn't?
I think the payee's computer had probably been malware hacked. (So I told her how to clean her PC and then I sent the same payment again as a one-off favor and that was ok, no further trouble and we still work together today).
