Or you could make the stock system more unpredictable. every so often have stock go bankrupt and all money invested disappears. then a new stock replaces the dead company? this would try to stop people from using stock as a bank with once a year tax instead of monthly. Also would make it more risky to invest all your money instead of just some of your money. Maybe give monthly or 1/4ly news papers that will hint to a stock that is going to tank or that might hit it big in the next few months? I think stock trade is the best feature in this game once you max your education its the only exciting way to earn money. Just a few ideas!
There should not be a limit on stock shares or investments. people with millions or billions would then think those features are useless and in turn stop playing.
Ok. There will be no stock limit. I will make just as you (and starfalls) suggested: stock will be more unpredictable in long term
