No matter the numbers of time we have lost funds in gambling, it is very important for us to keep looking for opportunities to win too so that we don't stay too boring and desperate for a win.
I think if someone faces consistent losses then it's better to stop gambling for some time until one can forget about the losses and begin a new session with a new mindset. I mean with a optimistic mindset, but at the same the the player should understand that gambling is not the way for quick riches and the chance of loosing everything is way higher than winning.
Most of the online casinos have their house edge and if someone's luck isn't so good then they can't beat the house edge of the casinos and tend up loosing again and again. I believe if someone is loosing in casino games then he should try his luck in sports betting instead of going back to casino games and lose even more there.
