My first 1k was like 15 years ago I think. Still in high school I was looking around ways to make money and "invested" in a pyramid scheme. Not that I really knew what it was back then. It tried to look somewhat legit but getting quite big gains after every 10 days or so (had to watch some ads every day tho). Young and stupid but that's how it was. In the end it was closed down before I could take all of the constantly reinvested money out. Hopefully people who needed it more got their money back (my real investment wasn't that big).
