That's right and we cannot afford to depend only on luck each and every time to make money and if we do so then we are putting our life at huge risk as you cannot expect that luck will favor you each and every time.
Since I'm not good in gambling I prefer investment too, there was a time in gambling that you became greedy. Even your losing you play and play again as long as you have a money. Other tell that gambling is like a drugs that you can't stop when you take it. And in investment we should make a backround check in every company or investment sites that we will invest, make sure that it is proven and legit.
for us that is not good in gambling, we can choose investment like above me and this is what i am doing too for now. because beside i am playing gambling, i want to increase my money with an investment and i hope that with investment, i can growth my my capital. i know to get ROI in investment is really needs a time and i am no problem with that.
