There was a story on the top of HN recently about an Asian student who came to live in the US and joined a hedge fund out of uni. He successfully predicted a huge windfall for his fund - but for entirely the wrong reasons. He put a lot of effort and research into his analysis of the market and was sure he understood it well enough to bet big. He failed but luck saved him and made a killing. His boss told him not to tell anyone, ever, and then promoted him. His boss was also promoted for his 'talent' in managing a successful team. The student was self-aware enough to realize he failed spectacularly and left the fund, but many aren't. Cognitive dissonance is rampant in the financial sector and with bitcoin everyone feels like a stock-broker, it's a dangerous game if you let your ego dictate your strategy.
