Ok, I would like to earn btc at purse.io. And I see that some people are ready to overpay 40-50% in btc for amazon goods. What's the point? I think it would be cheaper to change btc somewhere and buy with credit card. Are they scammers?
I don't understand your post, but those using their gift cards to buy something for someone else do it because it is difficult to transfer amazon gift cards and that is why as a buyer you can get discounts when buying from purse.io so it is a win/win, the buyer gets cheaper goods and the sellers get rid of their gift cards for bitcoin.
