Fear of losing money because of gambling, then it would be better for you to avoid gambling. But, if you “Don't FEAR” losing money then wasting money is something that becomes commonplace if you have a personality that doesn't care what you spend your money on. After all, the basis for starting betting is also basically the courage to lose money, because if you do not dare to lose money then when you lose then you will be very disappointed and angry, of course. So yes, if you are afraid then please avoid gambling, but if you are curious and want to try your luck, then you can start gambling even if only with a low nominal.
Fear of losing money in gambling is the beginning of wisdom. Normal you are going to loss money in betting but as time keep going on, you could start making profits gradually which is why we need to be disciplined and not gamble on every bet. You might not even make the kind of profit you are going to get as a gambler and the ones you never expected might be the one that will earn you profits. I do bet randomly which is why I have limited the way the way I bet even when I have money or I have made huge profits from the market. Gambling is addictive and we should always try to regulate the way we gamble to avoid addiction.
