They've added extra security to reduce the hacking. Also, you can only use real money at certain times in the week now instead of all the time.
I was making 40k a session trading healing cards.
Mass buying them for 400 / 500 coins and selling them for double the price. Easy money.
Doesnt work too well now though because the market is dying for FIFA 12.
Sounds good, but EA have always been shady to me. Are leaderboards still in fifa 13? One of the main reasons hacking was even an issue.
