I have 85k coins. I want to upgrade my team, but I don't know how to make coins. What do I do?
Spend money is the only real answer if you want them fast.
You can make coins without spending a dime but a lot of coins methods require you to have a decent amount of coins already. It's going to take awhile to accumulate coins if you don't spend. Sniping is always an option but involves a bit of luck. Sometimes there's profitable sets but those often require coins to obtain the pieces. You'll have to look for those yourself though because sharing profitable sets leads to them not being profitable anymore because of how many people do them. You can find a spreadsheet that will help you figure out which sets are profitable here
Buy low sell high, harder to do atm because the market is still adjusting to the overall increase
