Yeah planning about your session won't contribute that much to your winning,
But if you divided (for example 0.25 bitcoins) in to a lot of sessions rather than just wishing for that luck to hit in all in game do make a great difference.
Cause you also dividing the luck and multiplying it,making the chance of winning a little bit higher.
It is better for me if I just bet that 0.25BTC in one go than doing small bets on different sessions. The latter requires more time to accomplish. And if you lose, you don't just lose money, you also lost time. If go YOLO on it, you don't spend too much time gambling. Spending too much on gambling may cause to be addicted to it. So, bet all your money once. If you win, nice and good. If not, better luck next time.
But YOLO have higher chance of loaing though because it is hard to win for the first time after you log in to particular site. I have tried this before but with small amount for sure but in the end I just lose it luckily it was only small amount. This is actually good reason because after you lose big it will stopped you for a while and let you think for a while but still to spend on that huge amount for only one bet is pretty dangerous thing
