Trading on the transfer market and participating SBCs are the two fastest ways to earn FC coins in EA Sports FC 25. Veteran players claim they can make anywhere between 100,000 to 150,000 coins per week through sniping due to flipping of in-demand players during prime market times (ex: when Weekend League rewards are released). Players prices fluctuate from week to week, so watching for bargains that can be flipped for a profit is essential.
Another way is through playing Division Rivals and FUT Champions games which could give you a good lump sum of coins and packs. The more matches you win in higher divisions, the more coins per week you will receive, with a potential payout of 50.000 Coins if you can hit Division 2 or above where prizes really start to heat up.
SBCs are another fast method of making coins, especially when special promotions including the ones like Team of the Week (TOTW) or FUT Birthday come in as completing these can get you good pack rewards and some tradable players. Rewards for certain SBCs, such as Hybrid Leagues or Hybrid Nations are especially lucrative, sometimes even topping 100.000 coins worth of value when packing high-tier players. The reason for this is because back on past FIFA games, doing them over the likes of special events rewarded double your investment these times around due to the player markert shooting were inflating massively.
Even with the third-party FC-to-coin deals available, some players are still wondering just how much quicker it is to purchase a certain amount of coins than grinding out matches. Despite EA discouraging the purchase of coins from outside sources, sites like fc coins guarantee fast and safe transactions by giving upto 15-30 minutes to deliever the purchased amount as low as $8 for every 100,000 coins. It basically just allows players to jump the time investment and go start building a competitive team right away.
Time = Money as Warren Buffett Once said, and so for many FC 25 players, a few coins to buy are more cost-effective than hours of investment in the game. If you want to keep things in the game, then high-reward SBCs, making trades over marquee matchups and playing competitive matches will all help you make coins.
