Legitimate Address and Transaction

[knightjp]

I've been trying sell some times through an online portal. The buyer asked me for my Paypal email address. After I gave him the address and my full name, he said that I will receive a message from Paypal about the transaction and that I should reply with a confirmation. I received it and it came from an address shown in the pictures. I want to confirm that this is a legitimate address and transaction.

After that I received this message (attached).

So far in the span of 30 minutes, I have received 6 messages urging me to complete the transaction.
The so called buyer is also on Whatsapp, asking me to complete this transaction.
This sounds dodgy to me. What kind of shipping company requires payment by bitcoin? Also why do I have to pay for the shipping upfront using my own money? This wasn't mentioned my conversation with the buyer.

Is this legitimate?

Regards,

Julian

You never pay any upfront fee as a seller.

Ignore scammers that send fake Paypal emails telling you that you need to pay an upfront fee to verify/upgrade/or any other reason to 'accept' a payment.

You would certainly never have to send funds 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.
