I actually do a lot of high risk investments with a small percentage of my net worth -- bitcoin, options, you name it. But I do it with hard cash to my name. If I lose a chunk of that I don't owe anyone anything.
I just never thought spending someone else's money and then owing them was even anywhere close to my moral radar of things I would do.
The only one time I took a debt is for a car when I had the cash to buy it but it was 2022 and I took a loan at 2% and put the balance of the car in treasury and municipal bonds at ~5% and paying back the loan slowly while selling off the bonds. I wouldn't take a loan if I didn't have the money. Before I could afford a car I just rented cars.
