I don't have any personal experience with receiving this large of a sum of money, but I just want to put this out there. Something like $50k is extremely substantial, and as a company PayPal wants to payout money as little as possible. So I would not be surprised if you are hassled for proof on how you obtained such sums, called upon to pay taxes for it based on your jurisdiction, and more. PayPal gets suspicious and asks for more documentation when I've done transactions in the low $500-2k, so YMMV.
