Yes, that's what I think. Very simple and easy to answer such questions. Actually if you do not want to lose money, do not take anything risky like gambling and trading. Just do something more sure and you believe. Like me who is afraid to take risks, so I never jumped into the world of trading or gambling. I just invested in Bitcoin and popular cryptocurrency. And as you said above, to reduce or eliminate losses to gambling and trading, you can collect some money from the internet by doing various online jobs. That way you will not be afraid of loss because the money you use does not come from your salary. I myself do not like gambling so I use my side-jobs to invest.
