That's an issue with the payment manager, not the currency used for payment.
> Payment processing and facilitating has tangible expenses (cost) and payment processors do not want to get involved with any companies involved with sordid industries (higher fraud).
I agree completely.
> Patreon adopting crypto cuts out the middleman processor and solves both problems.
I disagree here. Presumably, the assessment that adult content is higher risk is valid, and Patreon would just assume that risk themselves if they didn't involve a third party payment processor, regardless of the currency used for payment.
Is your claim that fraud would be reduced because there's no real way to reverse a crypto transaction at the moment? If so, my stance is that accepting crypto would just open them up to other issues associated with fraud, and wouldn't be worth the effort.
> But crypto ia too user-unfriendly at the moment, so usage would be very limited.
I agree with this as well, which is another reason crypto isn't the solution here.
