I'm not a fan of gambling by itself, but instead as a way of studying and learning about other things. For instance, I'm sure that if elderly people kept playing card games, it would help keep their minds alert. Studying poker involves studying human nature and probabilities. There are other aspects like studying risk in gambling, which is like studying risk in investing.
Does anyone have any examples of how gambling is like investing?
Actually investing is saving of money to make sure in the future to grow the capital. And this will be risky because you can't predict what will happen in the future. Example, when you invest in bitcoin you can't predict if you can get a profit or it will lose. Same as gambling, you can't predict the time for winning and losing.
Differnce between the two, gambling winnings and losing will get in small period of time unlike investing that need to wait a long time. Both them are money involved.
