Again I dont really use this method but it is a good way of making coins.
Improving the card
This isn’t a greatly know method but can increase your profits by a couple of thousand a card. By buying up a card with fewer contracts, in a less popular formation, such as 5-2-2-1, we can make a good profit by making the card to what the buyer wants. By changing the card to a popular formation 4-3-3/4-1-2-1-2/4-4-2, increasing the contracts to more than the norm of 7, and buying player attributes for the player we can greatly increase the potential profit as the buyer can slot this card straight into his team, without having to do anything. The player attributes will also help make the card stand out, and so you will get more views on the card. The potential profit here is high, as again people who are simply building their team will not care as much about getting a good deal, but finding exactly the right card to slot into their team immediately. However, formation cards have increased in price recently with a 4-3-3 card currently retailing at 6-7k so this method is only viable for players with a market value over 50k.
Example
We buy a CM Modric, formation 5-2-1-2, with 0 contracts remaining for 59k via bid. We add 33 contracts for 400 coins, change it to 4-3-3 for 5200 coins and add player attributes for just 150, and put it back on the market for 72k start, 75k BIN, after 34 minutes it sells leading to a profit of around 7k after tax. This method will take a quite a long time but will generally always make profit of around 1-10k/card depending on which card you buy.Also, today 23/10/11 I saw a Messi 4-3-3 formation go for a bid of 775,000. I'm pretty sure this is the same Messi which was on a BIN of 705,000 10 minutes early, which would've left the seller with a profit of around 30k from 1 card after simply changing the formation to 4-3-3, showing the value of improving the card.
