Pointless. The occurrence or not of a particular number or set of numbers in past draws has absolutely no bearing on its occurrence or not in subsequent draws. Markov or something like that...
Fully aware of the doctrine of "Past performance is not an indicator..." but you then have to apply the same rule to any investment. So would that mean all investments are ultimately pointless?
There has never been a number that has not come out after x amount of draws, yes, x is unknown, but historically x does exist.
I dont have the bottle or cash to go through with it but I dont see how it wouldnt work if you had a large enough bankroll and a bookie willing to take the bet if the wager got large enough (at odds of 6/1).
