Investment is like gambling.
Some people want to invest more and earn more, but in many cases, the consequences of this idea are beyond people's affordability. When many people invest a small amount of money, they are always misled by others "be brave and try boldly." If they make money, they will be very happy and they will invest more and more. If it fails, it may require great psychological and financial affordability.
While some do invest like it would gamble, investing is
not like gambling.
One can properly check for himself and invest in what he think it's fit. He can choose for himself what risk he can take, he can choose a more or less reliable investment (of course, if he doesn't check this, then it would be gambling indeed). My point is that if one uses his brain when investing, he has a very chance for profit.
In gambling it usually doesn't matter much how well one uses his brain, the odds for winning are not big.
Gambling is for fun, some adrenaline and some occasional wins. Investments are for earning money.
