If someone can manage to hack the fifa web app so you can get unlimited coins or somehow get free player packs then they can make a fair bit of money selling coins on ebay but it is really hard to hack and EA are very quick to patch up errors or glitches. Also you have do it under the radar somehow otherwise EA will ban you. Iv'e tried many things but i am not expert enough at this stuff

Anyway if anyone has any free time they should give it a go

I think they may have to make a Fifa ultimate team account on the console first before you can use the web app. I'm not sure
