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
The chance of winning in gambling is very slim and as such it is better to gamble with little amount and last long in betting. I have play more than thirty bets with 0.005btc and win some and lost others but i have play 0.015btc and lost all. Since then i have learned a lesson to play with little amount as possible.
