Never ever gamble your hard earned money, i had lost more than what i had saved ever in life. I also was very careless while investing in scum icos, i have learned the lesson though the hard way. I will say just let the urge of gambling go and dont let dominate you.
You have made a lot of sense with the first line in your comment mate. I think only a fool will gamble hard earned money that should be kept as savings. I gamble spare and whatever amount I cannot afford to lose can never go to a gambling game. Maybe, because I set my budget at the beginning of every month. Just the way I set aside money for groceries and household needs, I dont forget to set aside the money for gambling.
If I exhaust it before the end of that month, that means no gambling again for me that month. I am also sorry about the money you lost to some scam ICO. I think this loss happens to every investor at some point, we only learn to be more careful before investing in any ICO.
