IMO you might as well just put it in the slot machine. If you grind these the variance is going to be massive. I know many people who have made their bankrolls by playing high stakes heads up, but not in Hyper turbos. If you would do this with a bankroll i suggest using something like 0.5% or 1% max as the buy in amount because you are going to have to play a TON of them. Like 80 a day or something crazy like that to be profitable.
