This is pretty nifty and if you don't need Paypal, you could conceivably have PMPro up and running with recurring crypto payments. I've been looking quite a bit for WordPress membership plugins that allow
BTC payment and this is all I've found:
- Paid Memberships Pro, via either your Plugin or Braintree (which integrates Coinbase). $200/year (free plugin, but will most likely require ponying up for the premium membership to access any of their 40+ premium addons).
- IgnitionDeck - WP crowdfunding platform that does memberships as well. It is WordPress, but it feels very much like you're in their distinct platform. $150/year
- MemberMouse - via Coinbase (or Braintree). Lots of nifty features, but it's really a complex system (and they obfuscate their code, so unless you get things working with their public API / push notifications, you're SOL). Either $20/month or $100/month for better reporting.
