To anyone who guarantees profit that is 100% illegal in USA FYI.
Well never say never, nothing is impossible imo. Also I would argue free speech and the right to defend the idea, etc. I'll have to quote a source on this but government backed and
guaranteed profit has very nearly been a thing. But mostly you are correct, I specialise in merit virgins so I gave 1 :p

Not sure if its game theory or just plain capitalism but always or guaranteed make a profit is a fallacy unfortunately. I would still argue it can occur in unpopular, emerging markets, sectors for some time, maybe years. That lotto thing went on for years apparently though they did make a loss in some instances; longer term it was against the odds to lose with their strategy amazingly, wish I knew
