The first one is the bronze pack method, which I'm sure a lot of you have heard of. I use it and amazingly, it works really well! You just need patience! I started off with 10K FIFA 15 coins and after a week of use, I was all the way up to 160K! And all I had to do was check back once an hour, relist expired cards and open a bronze pack or two! Make sure to buy FIFA 15 coins packs for maximum profit. Anyway, here's the best way to do it:
Buy a bronze pack and auction the following items for the following prices:
Contracts: Min Bid – 200 ~ Buy Now – 250
Rare Contracts: Min Bid – 300 ~ Buy Now – 400
Non-rare Players: Min Bid – 150 ~ Buy Now – 200
(If they play for a popular team [e.g. Arsenal, Barcelona, Real Madrid], check their market price as they may be worth more! I usually do players rated 56 and above.)
Rare Players: Min Bid – 200 ~ Buy Now – 250(Look at their stats, if they have high pace OR 80+ in anything, they may be worth more! Also LB/RB's with 80+ pace will almost surely go for more, especially if they are in the MLS)
Balls: Min Bid – 150 ~ Buy Now – 200(Balls may or may not sell, this is optional. I sell really nice looking balls that I get)
Managers: Min Bid – 200 ~ Buy Now 250 (If they are rare managers, make the Buy Now 400/450)
Fitness Coaches, Trainers, and Medical Staff: Min Bid – 150 ~ Buy Now – 200(If they are rare, make the Min Bid 200 and Buy Now 250)
