Inherent to Stripe processing BTC is the fact that you are now a foreign exchange broker. Here's a small sample of why you're going to have to do a lot better than "we only charge 0.5%" to convince me that adding FX risk into my payment processing stack is a good idea:

And that's just from the last three months, in an arena that is already heavily regulated by the SEC.

Hm? As a business selling with Stripe, you won't be taking any FX risk. You request $20, and you receive $20 - 0.5%.

I am a huge fan of Matt Levine's work, but the articles you reference are about banks who participate in the FX markets, which is... different.

(Relevant disclosure: I work at Stripe.)
