Too risky, risky to bet too big.
and too risky to lose a lot of money
I agree but it would be not risky if you know how to control yourself from betting big amounts and when to stop from gambling. If your too afraid to lose a lot of money better not to gamble and find some other ways to entertain yourself without any money involve in it. Gambling is fun if you know how to control yourself from it but it could also be harmful if you get addicted to it.
I seriously feel bad for those who say gambling is a fun activity, no matter if you control it or not. But in the end after a long run, you will loose everything. Why to make a habit of something which you yourself know will at the end only harm you ? Gambling is NOT fun at the end, may be in the beginning only.
