Paypal often freezes your funds which sucks cause its your own money. Bitcoin never does this and bitcoin has no transaction fees either so win win.
I also use them both but I like paypal right now a bit more due to the fact you can return the money you have put in it.
The fact is that bitcoin is good for profit but paypal for the security when you pay something.
It is not really that why I am using it. It is because I have no option. Online stores that cannot be payed through cash on delivery or visa. Only paypal. That is just so unfair. I will be forced to sign up in paypal, verify it until I can get what I want.
