I'll be 'that guy'. This is the number one use case for a cryptocurrency in my opinion - a decentralized microtransaction system.

This isn't the first time Patreon has faced these issues and services like PayPal are notorious for closing your account then giving you the finger.

I don't want to give my credit card info to 30 different sites or services or creators I want to support. I don't want a bunch of small recurring charges from different places on my credit card. And most of all, I don't want a service to arbitrarily be able to decide (or have others force their hand as in this case) what I am and am not allowed to support.

I don't think the technology or people are remotely near ready for mainstream adoption yet but it is still the most compelling use case I've seen.
