Humans are irrational, greedy, and repeat the same mistakes. In order not to repeat the same mistakes, we have to learn in history. History is not just a past. It is present and future is possible.
I want to talk about human greed rather than virtual money itself. Putting money in virtual currency like a bit coin is speculation, not investment. It is avarice to sit still and not to work and desire to increase wealth. Keep in mind that money is not easy to earn. You can shed tears this afternoon laughing at the surge of virtual currency yesterday.
Although the movement of the celestial body can be calculated, human madness can not be measured at all.
