PayPal isn't a bank. They don't have the same obligations or protection. When a bank closes your account, they mail you a check with the balance, and that balance is insured up to $250,000. I don't know how it works in other countries, but they probably have something like the FDIC.
well i havent had problems with them even if i held large amounts there, but my business with them was rather straightforward. Their KYC was reasonable
