This investment is actually worse than any of those listed. There is zero potential upside as well as the risk of complete loss of funds via theft, fraud or negligence. I'll pass.
Actually, anyone with a brain could see that the risk was way too high for the slim rewards - i.e. very little to gain in case of total success; and the risks of complete loss of funds are there with the others too.
(You understood that it's a joke, right?)
Yeah, I was being sarcastic with my serious response. I got a laugh, btw.
