Pay in cryptocurrency [enhancement]

[Zzoomrus]

Description

It's easier for me to pay for license with cryptocoin, like USDT TRC20, or another.

Rationale

I think it may be useful not only for me.

@Zzoomrus thanks for your suggestion!

Mac Mouse Fix 3 is using Gumroad as a payment provider and it's hard to change at this point because I've already done a lot of work integrating with their APIs and I also think they offer by far the easiest and fastest checkout experience out of their competitors.

So crypto payments are probably not coming soon, unless Gumroad adds support for that.

Let me know if you have more questions or suggestions!
