Ways to earn coins:

  • Collecting them in buildings
  • Increasing your Reputation
  • Random event to find a Spy.

You can also earn coins by spending Cash, but this is generally considered a waste of resources. For example, 100 Cash only earns you 25,000 Coins - you can earn more than that by selling a few of the bikes.
