I guess people in this industry are not primarily into money, but also to the benefits. But I would agree if it is the reason why many people stayed. Bitcoin, a digital currency in its nature, is now considered by many as a profitable investment. Currency as an investment? This is already enough to explain my point. Its volatility makes it different to other currencies both in digital and physical world. No matter how we view its benefit such as being free of tax, faster transaction and such, being profitable will still be on top. So I guess, this somewhat is making sense. Not in the aspect of adoption because that is another story concerning government policies.
