If you deposit at a gambling site then you should think what you deposit is already a lost that is why it will help to take some stress out if you really lose them all but if you make a little back then withdraw them and keep it safe until you decide to deposit it back to the site
This is a superb strategy.
then you was already addicted on gambling.
Not necessarily, how does using the strategy listed above "make you addicted to gambling"? I think that the strategy listed above is a good mindset to have while gambling, and will not "make you addicted"
