How would that work, though? If creators want to accept cryptocurrency, they can already put an address on their web site and watch the money rolling in. No need for an intermediate.

If creators want other currencies but you want to pay in cryptocurrency, Liberapay would have to do the conversion for you. But it's questionable why that would be a good idea. They would have to use yet another intermediary.

Which cryptocurrency though? Bitcoin is unusable for small payments, and others are still very volatile.
