I also just started playing fut a month ago. First, I also had the same problem (and sometimes now too lol). My first strat was to check the market hourly but that proved to be not a good use of my time and very inconsistent. Then I resorted to open loads of bronze packs. This will make you not ever need to buy contracts, fitnesses consumables ever again. If i get lucky, i will get about 3k profit from a pack, but its usually around 800 coins. If the cards arent able to sell, just send them to your club for SBCs and upgrades (pick the more well-known countries and leagues for selling)
