and from what I read so far, PayPal "gift" is actually quite secure for the seller and could actually be disadvantageous to the buyer if the seller is a scammer.
"Quite secure" is quite wrong. Even if the payment is sent as a "gift", the buyer can still do the following to defraud the seller:
- if using a link account, chargeback through their bank
- if using a linked credit card, chargeback through the card issuer
- enter a note on the transfer that payment is for virtual goods
If you'd like to sell me 10 BTC for spot, I can demonstrate the above.
