Ive seen this option on Bet365 and a few other sportsbooks and they are similar to day trading I feel. I used to bet on it a couple of years ago but it is hard to predict generally speaking. I'd say Dice is easier and has better value in gambling digital options.
I share your sentiments actually. Indeed, Bet365 was infact the first place i saw it also. For me, the Turbo mode option is quite scary, i'm not a seasoned gambler or trader. The way i see it, its much more a gambling on an off chance of being correct within such short time frame.
Agree, it's a bit scary, even if you are a seasoned gambler or trader. That rush and then the sudden lost of money could have a impact on your emotions. So I don't go with that option, I would rather gambling on dice sites because it's not that stressful and has a higher chance to win.
