> made me feel like an idiot for ever thinking that cryptocurrency was a good idea The very broad notion of digital currency involving cryptography is as good, bad or ugly as any number of other everyday concepts and mechanisms. There's no special inherent evil in that broad notion. Your investment choice, on the other hand, was average. Not terrible. Average. That is, you diversified, you lost some, but you're still around to play the game, and still ranking very highly in the overall human race affluence stakes. Snake Oil, or even simpler, mundanely-poor investments, from all walks of life, are the true basis of idiot bait. Digital currency involving cryptography simply is what it is. It's quite likely that the near-to-medium future of humanity will involve quite a lot of it, in some form or another (not at all like most of the current forms, of course).
