I do about $60,000 a month with Paypal, and I am withdrawing the money every day. Sometimes TWICE a day. '
A couple of years ago they limited my account for verification purposes, and asked me to give them over a dozen items to show that I was who I said I was. After getting all of that done, I have made it a point to always withdraw the money out.
If they want to, they will limit your account, and you will not have access to that money at all. Remember, Paypal is not classified as a bank, so therefore they do not have to adhere to the normal 'rules and regulations'
Basically, that money isn't even yours until it reaches your bank account.
