But it will be pointless to have that, we gamble to get profit, not to waste something like 0 bet, although it only to skip a few bets? What I mean, there is no point to do that, skip a few bets and that will guarantee your outcome? I do not think it works that way and I do not even know why someone would do this 0 bet from the start
I believe there were many PD users do this "pre-rolling" with 0 satoshi bet. It is just a part of strategy, obviously there is no guarantee that the outcome after pre-rolling will be correct/win. Just like other strategies where there is no guarantee to win. I did the same thing long time ago when I was hunting for big payout, indeed sometime it works (when we are lucky) but many time it does not work like what is expected.
