If we are going to fast, there must be a reason with that. It can be that we will do some other things after we play gambling. The worse thing on why a gambler speeds up is because they want quick profits. I doubt they will be successful with that. There are some pro gamblers that I saw who successfully made over 1 BTC starting from a tiny satoshi but they achieve it slowly. It took them longer hours or even days, weeks.
Only the very lucky gamblers manage to win big using the speeding technique, otherwise, if you are over speeding with you bets on any game, you are more likely to lose everything to the house due to the house edge.
