The habit that you have to avoid when gambling is:
Don't make a lot of bet while gambling
Making lots of bets not increasing your chances to win
It didnt decrease your chance either . you will still loose even if you are only betting small but this is better at all times . whenever i play gambling i tend to bet lower because i want to spend more time in that game .
some gamblers would be doing the other way around because they find it boring to bet less and it will only take time to achieve their waggering requirements
