I want Bitcoin to die in a fire: this is a start, but it's not sufficient. Let me give you a round-up below the cut. Like all currency systems, Bitcoin comes with an implicit political agenda attached. Decisions we take about how to manage money, taxation, and the economy have consequences: by its consequences you may judge a finance system. Our current global system is pretty crap, but I submit that Bitcoin is worst. For starters, BtC is inherently deflationary. There is an upper limit on the number of bitcoins that can ever be created 'mined', in the jargon: new bitcoins are created by carrying out mathematical operations which become progressively harder as the bitcoin space is explored—like calculating ever-larger prime numbers, they get further apart. This means the the cost of generating new Bitcoins rises over time, so that the value of Bitcoins rise relative to the available goods and services in the market.
Brass- and gold-plated physical Bitcoins are now available. Just don't let the FBI know Bitcoins aren't just an abstract financial instrument living somewhere in the digital ether anymore. They're now a physical currency capable of taking a ride in your pocket or scratching off your lottery tickets.
The cryptocurrency was invented in by an unknown person or group of people using the name Satoshi Nakamoto. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. Bitcoin has been criticized for its use in illegal transactions, the large amount of electricity and thus carbon footprint used by mining, price volatility , and thefts from exchanges. Some investors and economists have characterized it as a speculative bubble at various times.
Mike Caldwell spent years turning digital currency into physical coins. That may sound like a paradox. But it's true. He takes bitcoins -- the world's most popular digital currency -- and then he mints them here in the physical world. Basically, these physical bitcoins are novelty items. But by moving the digital currency into the physical realm, he also prevents hackers from stealing the stuff via an online attack.
