Some Japanese John Doe once had a criticism of money. Not that the average person always has too little of it and has to work long and hard to earn it. His criticism was that its price fluctuations make it unreliable for private payment transactions, and that it does not really belong to "all of us" who want use money to pay and exchange because all kinds of authorities from the central bank to speculators are involved and misuse it. The solution was quite simple: he invented a free money for free citizens on the Internet, bypassing the demonized authorities, and christened it Bitcoin. Now, a few years later, the stock market professionals from radio and television will explain to you how the price jumps of Bitcoin make it such an exciting investment opportunity, which, however, it is better for ordinary people to keep their hands off. On the other hand, if you have enough money left over that you don't need to spend, you can become filthy rich with a little luck by speculating on this strange something that the financial critic has put into the world. But actually, money is there for something other than what the critics of state-money imagine. Our article explains Bitcoin's career from digital monstrosity arising from a false criticism of the state's money to object for speculation.
