How do i make a lot of coins in ultimate team

I see a lot of people with a lot of coins and a really good team, and i was wondering what are some ways to make coins without having to spend a lot of money.

I made a lot of coin playing the auction house during December into early January. But my filters aren’t as profitable as they use to be and I don’t need the coin anymore. Unfortunately the only way I know of to build coins now is to buy packs, especially when they offer platinum bundles or packs with good odds for champions, and hope for good pack luck. I’ve had abnormal pack luck — pulled four LTDs at launch and made a lot off each, got that GF Wilson out of a customer grant that I did nothing to earn. Short of spending money you’re relegated to grinding solo seasons and solo battles for a 40k payout and some largely worthless packs. Sorry I don’t have any better advice for you!
