How to get free coins

All coins you get in quests are free, isn't it? of course you can spend to buy fc points which in turn can be used to gain coins.  If you r asking this watching YouTube videos where free coins are added to your account if you do XYZ link, I suggest stay away mate.  You might end up loosing more than what it's worth.  Play safe and have fun.. EA time and again does provide good freebies, so it isn't that difficult to manage a top quality F2P team.
