People wont exchange BTC for payment via Paypal, (and to be honest I woudnt either unless with a trusted party ) as Paypal can be reversed where as the BTC transaction can not.
Im new to this as well, and have asked if there is anywhere people can recommend off this forum that will accept payment via Paypal, but am yet to get a response, and I only want to spend $8 lol so you and your £20 have no chance
I can pay with some other method if requested, but paypal is what I mostly use.
I don't understand why I am getting negative feedback just for stating that paypal was my preferred method :/
