I never took this seriously honestly (Paypal or any other payment method) but do they allow trading Bitcoin?
No.
or it's against their TOS.
Yes, they have a clause about digital items and currencies IIRC.
I'm not sure how they are supposed to know if you are trading bitcoin or not , but I'd like to know if I can do it according to their terms or not .
also I want to know anyone of you know when the 21 days hold thing disappears from our accounts ? that should make bitcoin trading easier. (or anything else)
You can do the trade, you just dont get any help if the paypal payment is reversed. Not sure what you are refering to with the "21 days hold thing", but its been years since I used PP. Maybe someone else can chime in. Keep in mind that PP is reversible for up to 180 days. This includes gifts and every fancy payment comment people come up with.
