Whatever happens, you will get that money. Even if you can not get the account unlimited, you will receive the limited amount after 6 months. So calm down.
No, not true at all. PayPal will investigate the account. If they determine goods were acquired and sold legally, the funds will be released.
If they detect illegitimate business activity, based on their own terms and conditions (not the law), they will NOT release the funds. OP can then decide to start a legal procedure against PayPal to get his funds back.
