Choose a popular player that a lot of people want, and find his average price. To do this, check the lowest "Buy Now" price and add 100-200 to it. You need to make sure you are not trying to make a huge profit from just one card. Keep your profit around 200 coins per item. You also need to take taxes into consideration. 100-200 coins is not much, but you are not going to sell just one card. If you bid on 50 cards and just sell 15, you can quickly make a decent profit. Repeat this process to get a lot of FUT coins without playing a single game. Note: Make sure to keep things like market fluctuations and player popularity in mind when doing this.
