The Ponzi scheme Investor
One who invests in ponzi scams continuously is this. This is the person who thinks about get-rich-quick schemes.
People might think that this set of investors doesn't exist, but I can confirm that there are people that are addicted to Ponzi scheme investors. Regardless of how much they lose, immediately they see another Ponzi firm they will still put their funds. They are impatient people that want to make a profit without any stress or delay. I have a friend that dislikes investing in Bitcoin because he thinks it is a waste of time. He prefers investing in businesses that promise large profit within a short time.
Absolutely true and I can attest to this. The people here in my country was once being hypnotized with a different kind of ponzi schemes somewhere around 2019 and 2020. If the government didn't put a stop on it, a lot more people could've lost their money. However, the people doesn't seem to understand it as they think it was a legitimate investment because it's "paying" and they ignore the fact that it's sustainability is in a huge question.
Regardless, of the warnings the government have made to the public against these ponzi schemes, still a lot of people here are willing to become a victim just to make that easy money.
The researcher investor
I also fall into this category. I am the type of person who does not easily trust a certain investment unless I've done my research and see something promising about it, this is the same reason why I've missed some opportunities in the past as I was not convinced with those type of investments (non-crypto).
