Dear friend, not all advice needs a reason. And if you think this is not reasonable, then look for the problem in yourself. Gambling is a case where you don’t need a lot of words, because you won’t earn money by playing gambling. It is impossible to gamble for a long time and be in the positive balance, this is how the gambling business works, this is science, the theory of probability. If a gambling person starts playing, he will play for a long time, and in the end he will be in the negative balance.
Let's say no to gambling!
We cannot say no to gambling all because some people are there who couldn't control the way they are gambling because they can't manage themselves not to talk of gambling responsibly, in such case, this has to be an individual issue and not to be a general one, gambling is a means of offering to us fun and nothing more, but when we are getting other things aside being entertained, then that has to do along way from how we are gambling, while there are many others making fun and gambling responsibly even when we are not.
If you think that gambling only offers us a means to have fun and nothing more, then you are either not a gambler or you are just ignorant of the possibilities and potentials in gambling, and yeah, this is my way of saying that you are wrong.
Aside from having fun, gambling is offers us a chance to make money, profit. And in as much as I do not advise gamblers to prioritize making money from gambling over having fun, the truth remains that, gambling is never gambling without the chance of one making money from it, we all just have to chase responsibly, that is the most important thing, no body enjoys throwing money away, or dashing money out to some random persons on the internet when you arent doing charity, without the ability to make money from gambling, not very many people will be gambling, this I am very sure of, and I believe even the casinos will agree with me.
