It's a shame really, that so many people are financially and economically illiterate to fall for scams like a ponzi scheme and it's especially a shame that with already much negative press that Bitcoin is getting from various fallacies being used as valid arguments in article to articles with reports on thefts and hacks, Bitcoin users and suporters neither appear to be able to escape being labeled idiots who fall for a ponzi when this all blows up and people lose a ton of money.
But I guess that's just the way it has to be; "A fool and his money is soon parted."
Yeah, the only reason we'd ever do something that you wouldn't is that we're financially illiterate.
Not all, just those who unknowingly "invest" in a ponzi scheme.
