Fighting inflation is relatively easy because we don't have a real market here, only "sham markets". There is a simple measure to limit liquid funds: 1. Lower the maximum price for offers in the GHM to a maximum of 200,000,000 credits. At the same time, also limit the sale of goods in P2P direct trading to this sum. 2. Stop the "gold trading" of credit sellers.
3. Your program as planned by you.
It has amazed me for years that EA/BW has not consistently implemented any of the above in the past.
