Bitcoin has been much in the news recently, along with new words like ‘cryptocurrency’ and ‘blockchains’. When bitcoin first appeared some years ago, I was intrigued by the idea of a currency that was not issued by any government and tried to learn what it was about and even downloaded the software that supposedly enabled people to ‘mine’ the currency. I soon lost interest and gave up because I lacked the motivation. I am not really driven by the desire for money and the process seemed to be so complicated and boring that it did not have any intellectual appeal for me either
John Oliver tries to explain what all these things are and how they are related. It is not easy and I think he is only partially successful but it was a good effort nonetheless.

Thanks.

I am puzzled. I thought YouTube videos were available globally. Is that not the case?

People can put geoblocks on their YouTube content, and sometimes YouTube blocks content regionally at the request of a third party. I’ve run across music on YouTube that was blocked from playing in North America at the request of the copyright holder, European TV clips the broadcaster won’t let be viewed outside their intended market, and videos where the audio has been removed because of a song used.

One thing that is starting to get more coverage is the amount of energy that mining uses. What is not explained much is that this is completely artificial and could be reduced significantly by changing some arbitrary rules since they add no value (other than attracting more miners). But it is also possible that there are things I’m not seeing because I’m not completely up to speed with the whole process (far from it actually).
We have cheap electricity and cold weather here in Quebec and the number of crytocurrency mining projects that the Hydro-Quebec (public monopoly) have received could use a quarter of what is currently being produced in the province if they were all accepted. That’s a huge amount of energy for very little actual benefit.

My favourite Bitcoin explainer is probably this one: A guide to Bitcoin: The amazing investment based on dream gold invented by a wizard.

I wouldn’t go near bitcoin for multiple reasons, with this latest one being perhaps the killer, Child abuse imagery found within bitcoin’s blockchain (Grauniad edits in {curly braces}):
Reginald Selkirk says
You don’t really have to know or understand anything about blockchain technology to recognize that cryptocurrencies are a bubble. The value is rising dramatically with no obvious basis in reality, the prices are fluctuating wildly, and most people are buying not because they have a need, but for speculative reasons: they see the value rising and assume it will continue to rise.
Some background reading on historical bubbles like the Mississippi bubble or the Dutch tulip bubble would be instructive.
I hope that after the crash they look up those people they interviewed and find out if they got out in time or if they got caught holding the bag. Because in a bubble, someone always gets caught holding the bag.

John @#13,
Thanks so much for the illuminating article. I have been intrigued by the story of the tulip bubble and what that article says seems more plausible than the wild stories that have been circulating.
I recently saw a film Tulip Fever that had the more popular version of this story as the backdrop for a romantic-comedy-drama. Although it had a good cast (Alicia Vikander, Judy Dench, Christoph Waltz, Tom Hollander, Zach Galifianakis) the film itself was somewhat mediocre. The scenes of people wildly buying and selling tulip bulbs in taverns and how the records of sales were kept were fun to watch, though.
