Paypal is a unethical organization that looks like a legit business. It is simple as that, no company in the whole world could get away with you not getting paid while actually using their payment processor. Think about bitcoin that way and how horrible that sounds, you give someone fiat on paypal, they give you bitcoins, then they make a chargeback and both end up with your fiat and their bitcoins back and on top of that you are charged with a fee for it. You would hate bitcoin if that was the case right?
Well, paypal is doing exactly that and they are not getting any punishment for it. Paypal WAS a good payment processor back in the day, not anymore. People realized how damaged their system is and moving away from it, it is the system of 2000-2013ish years, and have been going down every single year since those days.
I have heard so much complaints that were unresolved, so I never trust paypal too, besides that their fee is too high which was not really right compare to the big exchanges, so I never used it as I checked their reviews first before having it, but I doubted it, also asked my friends feedback and they were all unsatisfied with paypal.
