The reason behind my statement is that no strategy can beat the house edge which all casinos have together with the luck factor.
There are some strategies like martingale to have some profits by gambling but it is also not going to give us 100% win on bets.Maybe cheating can be a strategy though but I won't do it.
how can you bring your luck when luck is verry rare to occur ? we dont control it and we dont have the ability to bring it to us . luck just strike randomly in unexpected manner . you did mention martingale , to be honest i also use that strategy before and i can say that its worth it because i can win more often compare to when playing randomly but its only good for several tries . if you use martingale in the long run , you can still experience to loose .
