Determining when an investment is too risky is a tricky proposition. It's important to consider both the financial and non-financial risks that are involved in an investment, as well as how you feel about those risks.
You have to consider the financial risks. If you're investing in something that has a high chance of failure and it's going to put your financial future at risk, it may be better to stick with safer investments that are more likely to pay off.
Also, you have to consider the non-financial risks. If you're investing in something that has a high chance of failure but isn't going to put your finances at risk, then you can probably still make money off of it if it does succeed—but if it fails, then there will be consequences outside of just financial losses. For example:
- If you invest in a new business venture and it succeeds, but then turns out that one of your employees stole money from the company, this could lead to legal action against you personally or even criminal charges for fraud or theft.
- If you invest in a new business venture and it fails because no one wants what they're selling or because their product doesn't work as advertised, then people may still sue them.
