There will be times where you will take a risk, and in the end you will not get rewarded.
There are some people out there who wants to invest into different assets, but they can't afford to risk their money because they're afraid they might lose their money. There are some who are a bit conservative when it comes to investing that they only use small amount of their money, and they only invest into the safest assets like Index Funds, Bitcoin etc. There are some who are just straight up risking all of their money hoping to get as many rewards as they can.
High risk = high reward, and it isn't only applicable in investing, but in other aspects of life as well. I guess it's only a matter of how much risk can we take or not. Like I said, risking everything doesn't mean that you will still get rewarded.
