Hi my fellow friends. First of all Im writing this using my phone so Im sorry if article seems badly. 
I want to suggest some stuff to show that gold flow can be taken under control without making changes like 1g for billions. 

1. Remove True Ally medal completely. 
2. Provide cc instead of gold for medals like Hard Worker, Super Soldier, Congressman, President. Mainly medals like we are getting without fighting.
3. Change law costs. 
 - Declare of war 50g instead of 20.
 - Attack a region 20g.
 - Sign a MPP 30g.
 - CPP 60g.
 - Sign peace 50g
4. Start a RW for 30g instead of 15.
5. Make different themes for the game and sell them. ( Dark theme, blue theme, pinky ass gay theme for defection etc )
6. Remove Defence System and Hospital. Turn them into permanent buildings and charge states a maintenance cost. Like;
 - Install a defence system 30g.
 - Maintenance cost for q1 level → daily 2g
   Maintenance cost for q2 level → daily 4g 
   Maintenance cost for q3 level → daily 6g 
   Maintenance cost for q4 level → daily 8g
   Maintenance cost for q5 level → daily 10g
 - Maintenance costs are daily because in times of war regions will change hand day by day. So in war times states can activate their defence systems and use them properly. When a region change hand ofcourse ds will be destroyed.
  - Install hospital cost → 60g 
  - Maintenance cost for q1 level → 0.2g daily
    Maintenance cost for q2 level → 0.4g daily
    Maintenance cost for q3 level → 0.6g daily
    Maintenance cost for q4 level → 0.8g daily
    Maintenance cost for q5 level → 1g daily
  - When a region that have hospital have been conquered then hospital will be destroyed as always. 

These are my suggestions for now. I just want to show that this could be made without making such silly changes that we saw today. Thanks for reading.
