I run a VPN service designed to get around censorship. Customers are mainly people in countries like China, Iran, and Russia. Unfortunately those countries don't have easy access to common Western payment methods (credit cards, PayPal etc.)

I thought adding a cryptocurrency payment option could give more people access, but I don't have any real experience in the area and the information I've found searching online seems extremely unreliable.

So I'm hoping I can get some better answers from Hacker News. Here are my questions:

1. Is crypto a good choice for this use case? Are there other options that would achieve my goal (allow people who can't use Western payment methods to pay)?

2. Could I start with one or just a few specific cryptocurrencies? Or do I need to support a whole bunch of different coins?

3. Any recommendations for self-hosted tools or third-party processors for actually accepting the payments?
