I feel that the solution isn ' t money sinks , GTA online has money sinks and it ' s a nightmare for new players . The best way is to have a LIMITED amount of currency in the game . Examplenumbers made upLet ' s say there ' s 1 , 000 , 000 players total in the game , simply make the currency limited to 1 , 000 , 000 , 000 credits . So split equally each player would get 1000 credits , as long as they had an algorithm person monitoring not controlling the value of the currency , they can set the prices that NPC ' s will work with , every credit given to an NPC is added to their total wealth , every credit given by an NPC is accounted for . Every single transaction . Within literal HOURS assuming they have a team of staff on this a really good algorithm the economy would have a value set . Next influenced is simple supply demand , the more people want an item , the higher the price , simple . Wouldn ' t hurt the economy if we could trade stocks and the value of the economy itself , we ' d need an alternate economy to trade which I dont think is a hint but who knowsJust my two cents . Not an expert on this , just read into stuff like this and this seems like a good option
