Don't even touch paypal unless you're ok with tons of limitations and your funds held for several weeks. If you can get past that, and you are fine with all of the fees then go right ahead. Why use paypal if you have bitcoin?
Yeah since bitcoin is there we must use bitcoin as it is more convenient,safe and fast at all. Unlike paypal who is really charging very high fees and as well as hidden fees. It is better if we are going to boycott the use of paypal if we can fully use bitcoin for transferring and accepting payments from our clients and customers.
The Paypal charges higher fees maybe because the banks charge it higher fee. When it uses bitcoin, the fee will be lower.
