I think they are not so friendly! I used paypal for trading a bit on LBC, and now my account is frozen. Now they want my life history data to release MY money. I can now see why so many people hate paypal, and I am glad that bitcoins are making a strong showing this year.
Paypal for products is ok, not the best but ok.
Paypal for crypto is horrible. With the world of charge backs, higher priced BTC, it just is not very good.
I suggest looking into a real exchange you can connect a bank account up to. You will save a lot of money overtime.
