Why is it always taking forever to sell a player on EAFC mobile????

There is no market for mid end cards (98-100), the price moves everyday, probably EA makes the price move, there is no buyer at all.

For cards between 86 and 97, EA offers cash exchange, most cards are trading just around the cash value, Don't try to sell them because of the 10% commission you will get nothing more than the  cash exchange value.

However the 103 cards are easy to sell or buy, and low end markets are strange these days, a lot of 79OVR cards are selling between 100K to 500K range.
