The reason I find it dubious is because $100k is not very much. You need to make very large trades--risking thousands of dollars at a time--or else you'll be eaten by fees and commissions. I don't know anything about day trading, but I used to play poker (profitably), and know sports betters. $100k is simply not enough to be risking thousands of dollars on single bets, unless the bets have an enormous edge--an edge that is economically impossible in the algo-dominated, limited-information world of day trading. You will go bust. I could produce math for you, but I'm lazy. But I've seen so many poker players go bust taking risks like this, and poker is a game where it's unbelievable how many morons are willing to throw money at you. Not like day trading.
