You never pay any upfront fee as a seller or to receive payments to your paypal account balance.
Ignore scammers that send fake Paypal emails telling you that you need to pay an upfront fee to verify/upgrade to a business account/or any other reason to accept a payment.
You would certainly never have to send funds especially via another payment processor/bitcoins/ or tokens/vouchers of any sort.
Any fee is auto deducted by Paypal at the same instant the remainder of the payment is credited to your Paypal account balance.
No funds in your balance = you have not yet been paid, even pending/held payments will still show in your Paypal account activity.
