What would you use paypal for in the purchase of bitcoin, particularly if you're not concerned about chargebacks? They're just going to charge you a fee and you've already stated you're not worried about the risk...so what do they offer?

I did a google search and can't find any opinion paypal has on Bitcoin...so maybe they don't care? They process payments. Ebay, however may have a specific stance on it.

I've bought bitcoin (casascius coins) from ebay but paid with a credit card...lower fees, no issues.

Here's a very recent article on ways to buy bitcoin via paypal: https://coinsutra.com/buy-bitcoins-using-paypal-working-options/

Hope this helps!
