What [bitcoins] lack is their own fundamental intrinsic value. You can’t do anything with a bitcoin, other than trade it for something you want. So, intrinsically, the bitcoin itself has no value. It only has value as a medium of exchange so long as people are willing to accept it.

I think there are two realistic directions the bitcoin ecosystem could go in. First, it could just implode and disappear if governments decide that virtual currencies cause too much harm and are too hard to regulate. Long-term investments in bitcoin would then go up in smoke. Second, it could continue as a virtual currency that is only used on the dark web with exchanges that are run by people willing to break the laws. The value of bitcoin would decline to whatever the illegal sector could support; regular investors wouldn’t be able to get their value from bitcoin unless they cashed it in with someone who wanted to do bad things.

Bitcoins will never achieve this. It is a mania going up. It will be a mania coming down. It will not increase the division of labor, because people will recognize it as having been a Ponzi scheme, and they will not again buy it. They will not use it in exchange. Companies will not sell goods and services based on Bitcoins. Bitcoins have to have stable purchasing power if they are to serve as money, and they will never, ever achieve stable purchasing power.

You can either work doing something useful, or you can set up a botnet to mine BitCoins, or you can fork the code behind BitCoin and set up your own slightly-tweaked virtual cryptographic money network. Setting up a new, alternative network is really cheap. Thus unless BitCoin going can somehow successfully differentiate itself from the latecomers who are about to emerge, the money supply of BitCoin-like things is infinite because the cost of production of them is infinitesimal.

Watson sounds even more negative on bitcoin. “I’ll be surprised if bitcoin is here in five years,” he has told Fortune. “The value of bitcoin isn’t the currency, but the technology. I think once the world becomes more accustomed and attuned to the platform of bitcoin, the noise will go away, and the currency will go away too.
[…]
Minor, too, predicts that bitcoin as a currency “will get destroyed.” He likens the coin’s current market cap—about $3.7 billion—to “an accounting mistake or rounding error that Bank of America makes.”
