Sunday photoblogging: door

I was going through my archives looking for black and white photos (for a competition) and this one stood out, despite its dull subject-matter.

Door, Welsh Back

Quizzical

With the huge upsurge in the price of Bitcoin recently, I’ve been getting a lot of demand for articles putting forward my point of view: Shorter JQ: It’s an environmentally destructive Ponzi scheme that isn’t usable as a currency even for believers.

My observations on the electricity demand associated with Bitcoin made it into the ABC (Australian equivalent of BBC) News Quiz last week, which is a kind of fame, I guess.

Meanwhile, I had another piece in the Guardian, this time looking at the fact that, despite being called a “cryptocurrency”, Bitcoin is used even less as a currency now than it was several years ago. The core problem is that the system is so overloaded by miners creating new coins that processing transactions is slow, costly or both I mentioned the fact that game company Steam had stopped accepting coins and that the list of merchants accepting Bitcoin is small enough to fit on one page. Checking further I concluded that this list is out of date, but not in a good way. Lots of those included, such as Expedia, no longer accept Bitcoin, if indeed they ever did. Here’s one person’s experience. Bitcoin is now a “crypto asset” which is even more obviously a Ponzi fantasy than the original currency story.

One response I got was that transaction speed would soon be greatly improved by something called Lightning. Checking on this it appears that this is software in an alpha (very early) stage of development, which would allow any two parties to set up a transactions account separate from the main Bitcoin blockchain, and only occasionally update the main account. An analogy, for readers of a certain age, is the era before Bankcard, when, if you wanted to do something other than paying cash, you maintained a separate credit and debit account with every store you dealt with. This does not seem like the dawn of a new era to me.
