In the old Earth 2025 they limited the money you could have once you hit 2B. Does Earth Empires have the same 'bug'? Are you limited to $2B or are you free to carry more?

You can carry more but the excess will decay like food (unless you invested in corruption bonus)

They decay rate on money is good determent to run turns with more than 2billion. But it helps when destocking that you can have more cash on had at any one time (dont use turns!)
