Some people avoid it but some people will keep playing because they are making money. I dont think that it is suitable for everyone because whenever I try to make money from gambling, I always lose everything that I bring. Some people have some good luck and managed to win some money although in the end he will most likely lose everything again
I prefer to gamble than trading because I am accustomed to fast thinking and active analysis every minute, no fundamental analysis is needed because it will release momentum in every period. Gambling risk is bigger but not at all disturbing if we are comfortable using it.
