The only serious bet you can have on the stock market is to start with a baseline of say, $10,000 (or whatever amount), on a given day, say February 1. Then 90 days later (or whatever date), is the balance higher or lower?
Not sure what else you could bet on a dare like that.
WTF you two talking about. Sounds like some cocaine is intertwined with your little made up bet, because neither of you makes any sense.
