The history of bitcoin thefts, hacks and simple disappearances (because holders lose the “private key” needed to use the bitcoin) is long and getting longer. We’ve seen the collapse of the Mt. Gox bitcoin exchange in Japan and heard many other horror stories about missing or stolen bitcoins. This article gives us the latest example.
Here’s the deal. Bitcoins are created by so-called “miners” (not real miners, but large-scale computing operations that solve increasingly difficult math problems both to validate existing bitcoin transactions and to earn new bitcoins as a “reward” for doing the math). The amount of computing power needed and the electricity needed to run and cool the computers is immense.
It is estimated that bitcoin mining today uses electricity at an annual rate equivalent to the total electricity consumption of Nigeria, a nation of over 90 million people. That usage will soon exceed the annual usage of Japan, the world’s third-largest economy. (Of course, things will never be allowed to get that far, but that’s another story.)
Large computer farms are springing up in China (because of cheap electricity) and Iceland (because it’s cold, which helps to cool the computers). A company called NiceHash had an idea to connect miners to people with spare computing capacity that they could make available to the miners. It’s something like the mainframe “time sharing” from the early days of computing in the 1960s and early 1970s. (My early days as a programmer were spent using mainframe time shares, which we had to reserve in advance by the hour.)
Not a bad idea, but the system security was not up to the task. According to this article, $60 million of bitcoin stored by NiceHash have gone missing. Even worse, the $60 million loss estimate was based on a $10,000 bitcoin price at the time of theft. Using today’s price, that loss could be $90 million or more.
In these conditions, it’s difficult to regard bitcoin as a reliable “store of value,” part of the basic definition of money.
It’s clear that good science does not support the extreme claims of the climate alarmists. Yes, there is such a thing as climate change, but it’s slow, difficult to predict and almost impossible to model because of the complexity of the process. The climate alarmists have grabbed most of the headlines for the past ten
