Thanks for your input!

I am sorry I just realised that I was not specific enough. I've been wanting to build a service platform to offer services where people were not restricted to use a certain currency for certain services like paying a transaction fee. So imagine something like MEW for ethereum with the difference that you can pay tx fees with Euros or  BTC.


My problem is this right here: Braintree acceptable use policy: https://www.braintreepayments.com/legal/acceptable-use-policy


Wouldn't Paypal block my API key as soon as the visit my site? Here their acceptable use policy: https://www.paypal.com/us/webapps/mpp/ua/acceptableuse-full

What payment service providers would be willing to work with me?

I can buy BTC from coinbase via credit card but I can't find a payment service provider (like Paypal or Stripe) willing to offer their service to somebody exchanging BTC (or any other crypto)
