If you have a high tendency to not stop until busting, then I came across these tips which do help:
- Don't put all your available bankroll directly in the game (in case you're using deposits). Leave always at least half outside as a security measure if you go bust.
- One must stop after reaching a certain goal, The goal should be predetermined and shouldn't be changed during the play.
- If you're doing really good, withdraw part of your earnings (if you can, ofc) to avoid losing it all in one go.
Having a big bankroll can make you feel falsely safe in that "oh I'll just keep increasing my bet until I win" but alas, the 30 reds in a row do exist, and will come. Do not let them take it all.
The goal you make should be realistic and firm, Don't change it or else be prepared to face bad consequences.
You gotta fight back the voice that screams inside your brain "Come on, double again and we recover!".
You have a good advice, but you can't stop people for what makes them happy. When a gambler decide to put their money on the line, they usually do it without any hesitation. So advising them to stop when they feel like lossing it all is pointless unless the gambler himself is determined to stop.
