d2 economy is the most flawed of all things, item to item trades long ago in history were a pain in the first place, that is why currency in form of coins came into existance which made trading much easier. If we had item to item trades, rs economy would collapse. As far as this 2.1bill cap thing goes, can you confirm that once you have that much in the bank that anything added ontop of that into the bank the cash would just dissapear? Because my theory is that it is just a display bug or maybe just something like it would show only 2.1bill and when examined perhaps would show more, or maybe the examination would show 2.1bill also but when some money is withdrawn (money would be something like lets say 10mill from a total of 2150mill and maybe another 80mill withdrawn from that and finally the money in bank would say that you have 2070mill.)
