7) Bid on silver players for SBC This has given me the most success, MLS, Liga Nos, Sydney fc....we went short on choice. The smart people list these players up with a minimum and maximum BIN that they are happy with. Then there are those that leave it on an open bid. The amount of times you can undercut the markets cheapest BIN by a thousand or two, and within a couple of listings sell it, is ridiculous. There will always be demand for these players, it's just ensuring your card is listed when those people search.

This is the absolute best method. Ignore Goalkeepers and most strikers. After awhile you'll memorize what the price for the silver MLS/Liga Nos cards normally is and be able to snipe some 59 minute steals and also bid your way to winning cards for about 500 coins that sell for 2k easily.

This is the most important part: Always sell the players with a buy it now and the bidding price at 50/100 coins less than the buy it now. For example, you won a bid on a player for 500 coins. You're going to relist that for 1100 bid 1200 buy it now. Then, you just keep relisting that card over and over all day until it sells.

Using this method, I've made about 6 million coins. If you don't believe me, here's a screenshot of my team http://imgur.com/a/pJkVE

I can make about 1 million coins a day using this method, but it involves a ton of relisting and bidding/sniping. Luckily at my office job I have a lot of downtime and can check the market listings every few minutes.
