First of all, I wish everyone happy earnings and peaceful business with Paypal. I do not want to scare you, just friendly warn that one day can change everything, so be prepared. Don't trust in Paypal (PP) 100%. It is good when everything is good, but one morning you can wake up and find out your account has been limited and all your financial life has been paralyzed, regardless the fact how good you was with PP. Without any reason. Just because. Because they are Paypal and they can do that. This is the main reason.
