Never ever rely on making money for your daily needs in gambling activities, because you won't survive with that kind of strategy. I am not against gambling because sometimes I feel to bet but I do not rely on luck. If I needed money, I work hard for it. The only time I will invest my money is when I have extra money, meaning I already set aside funds for my daily needs and for an emergency.
People all over the world have always had different approaches to everything. Some try hard to earn money, some try their luck. And the lowest risk is always to win by working. Nevertheless, luck is an important part of human life.
For example we are trying our luck with BTC now. Let's see if it will smile us.
