Didn't realize OP sent wrong amount via Paypal.

 

At OP you didn't even send the full payment, then you complain that he didn't send you the full Bitcoin?

Agreed price = 47.77$ Paypal // you sent 47.25
Agreed price = 43$ worth of Bitcoin // he sent 42.21

I'm confused with your argument here.

 

This trade is ridiculous. OP sent the wrong amount of Paypal, now still is insisting on the original deal.

Furthermore, the amounts being disputed here are negligible and do not belong in the scammer forum.
