What term describes an individual who enjoys investing money into high-risk ventures?

The term that describes an individual who enjoys investing money into high-risk ventures is "risk taker." A risk taker is someone who is willing to accept the possibility of loss in exchange for the potential of higher rewards. This personality trait is often seen in investors who choose to participate in volatile markets or invest in startup companies, cryptocurrencies, and other high-stakes financial opportunities.

Contrast this with terms like investor, which is a broader category that includes individuals with varying risk tolerances. Conservative typically refers to someone who prefers low-risk investments to protect their capital, while security seeker indicates an individual who prioritizes safety and lower returns over higher risk. Thus, "risk taker" specifically captures the essence of someone who actively seeks out high-risk ventures for the possibility of significant financial gain.
