If you already bought an asset, you are considered as a risk taker already because you are taking the risk of a potential loss.

It all comes down to how risky an investment or an asset maybe. Bonds is an asset with the lowest risk. Stocks has more risks than Bonds, but lesser than crypto, and speaking of crypto, it is for me the most riskiest investment currently. As long as you invested into something that can't give you guaranteed returns then I guess it is considered a risky investment. Whether it will be precious metals, or things you got from an auction, or an NFT whatever, as long as it's an asset, you are already taking risk because you don't know if you will get profit or loss from it. I forgot that business is also added because you are risking your capital into building one.

Well, I already bought Bitcoin years ago, so I guess I can consider myself as a risk taker already.
