Interesting news article but the whole redirecting people to a competitor kind of hurts your original thought. I used purse.io back in the day (when it was first started) and had no problems. I stopped using it a few months in when there was too much competition (I was mainly a buyer who gave btc for the discounted amazon goods). It seems a lot of fraud appears on the website now.
Gyft is an entirely different business though. Gyft resells its own gift cards, so it is clear where the cards originate from. On the other hand, Purse.IO simply acts as a middleman to connect buyers and sellers, and the origin of the discounted Amazon credits available may be uncertain.
This is true. With gyft there is a chance that you are buying goods via a stolen credit card. In exchange for that risk you generally will get a larger discount (~10%+ verses only 3% on gyft).
Purse seems to be improving their methods of preventing people from buying large amounts of bitcoin via their platform with stolen credit cards via the limiting of how many and how big of purchases they can make
