I tried some Woo-Commerce? plugin to accept Bitcoin on my sites a few years ago and Paypal baulked at it or made it incredibly complicated to the point that I gave up. Stripe said to wait until their cryptocurrency was released.

The main issue at the time seemed to be that it couldn't really work as a medium of exchange. Eg; $100 paid on the Monday might be $80 or $150 by the time it actually cleared. Maybe I was really inept but I got sick of the complexity and bailed, even though I liked the idea of having these options.

I wouldn't try Paypal's offering as they don't have any kind of quality support for merchants.
