The introduction of the stock market?

I remember when it got introduced I got 3 7's on a slot machine and won more money than I ever had (that round), then every kept buying negative value of stocks and selling them. This exploit was used so widely BSF did a rollback to 9:00 the day before. I logged on the next day to find out the bad news, I had just enough money to OC. I oc'd, it failed. I quit.
