Two mistakes gamblers make, first they don't play as fun but instead they want to make money quickly and they get pressure into making mistakes and they lose that particular bets, it doesn't matter whatever game they're playing. It could be live casino games or others.
Almost 80% of gamblers gamble to make money only 20% will gamble to have fun. This number may increase when you talk about online gambling. In physical gambling, you go out to gamble with friends but online gambling is just done to get some money in the comfort of your home.
Second, they don't stop when they're losing, instead they chase after their lost and want to make profits to cover up, they don't realized that when chasing losses they aren't playing with clear eyes and can get easily pressured to make the wrong bets in whatever games they're playing.
Revenge gambling or playing more and more in order to recover the loss, will give you more loss than profit. Gambling requires you to have a piece of mind before playing but if you are playing to recover your losses you will make more wrong decisions.
If you're losing just stop playing, and come back another day to continue playing. Gambling shouldn't be over done or you can get easily influenced and it turns into an addiction which could take a very long time to get over.
This advice has been given many times to quit gambling on both occasions if you are losing or winning. It will help you to stop more losses and in case of the wins, it will help you not to turn your winning amount into a loss.
