I've never used a cash back firm before as I thought they were gimmick companies. But I'm seeing a ton of them that seem to be thriving, so I started to look at Cashbackforex, Pipsafe, EQLX, Pipkingfx, and Paybackfx. I don't care about getting paid weekly or whatever, thats not why I'm trading, so what else should I look for to narrow this down?
