I used IF trading until i reached like 8m, bought at a team and the inflation helped me reach 15m lol. I still think you can do it tbh. Just buy a legend, use him for a couple of days, and sell for 25-50% more. Or buy loads of the current TOTW players. Just make sure you have all your coins tied up all the time.
Btw, sell Ibarbo if you have one. He costs like 50k atm because people panic buy him now that his transferred cards is a RW lol.
Nice goals, gotta love long range FKs
