Someone cleverer than me will explain it better, but a bitcoin isn't anything other than something that enough people have agreed has value.  It's like trading in an IOU that can't be paid, but everyone agrees has value. I some respects that's like a fiat currency, but ultimately they're backed by a government. They can (and do) default too, of course. But that has repercussions.

The blockchain (and the encryption) isn't to do with bitcoin, per se, it's the mechanism that makes bitcoin tamperproof, otherwise I could just claim that yep, I have a pile of bitcoin. The ledger proves whether or not I don't.

There are multiple blockchains, it's just that longest wins out – that's where the work comes in, as mentioned earlier.

Supporters of bitcoin would argue that it's no different to fiat currency, which isn't backed by any underlying asset (e.g. gold) either.  However, fiat currency is backed by an identifiable government that has public assets, can borrow money itself, and can raise money through taxation.

Bitcoin is worth something because, currently, people are willing to swap real money for it and it is also untraceable, so you can buy illegal stuff with it.  Also FOMO (see South Sea and tulip bubbles for previous examples).

You can argue that gold has no intrinsic value, but its value as jewellery is so high and consistent that prices have to be seasonally adjusted to take account of the Indian wedding season.

It's not untraceable though, it's everything but, there's a nice ledger recording every transaction from creation onward. That can be (and has been) mined to identify transaction patterns and tie those to individuals and organizations. There's a business doing this for bitcoin and other cryptocurrencies.

Swift’s can fly 800km in a day.

Swifts can fuel up on insects without landing, which allows them to remain in flight for about 10 months of the year.

According to a different report I saw they can not only refuel but preen in flight.  I wouldn't be surprised if they could start a family at the same time.

They do. The only time they land is at the nest. They mate while flying.

They also sleep while flying.   A series of nano sleeps apparently.

Some fun facts about swifts (one of my favourite birds).

well, they aren't called "Slows".

We live about 8 miles from the large, tall chimney (now disused) of a school building.  It's on the swifts migration route, and for about a week at the start and end of summer large flocks of them circle it just before nightfall and then all fly straight down to roost.  Local predator birds noticed this, too (along with the humans sitting on portable chairs to watch the spectacle), so measures were taken to make the area less friendly to them.

That the "Care in the Community" policy originated with Enoch Powell in 1961.

Around my locale, there are many former mental hospitals and asylums, all now housing estates and golf courses. The one that pioneered psychosurgery is now the Greatpark Estate. There's another, Caterham, which is now the Surrey National Golf Course, other than the small and atmospheric graveyard – that was where the infamous (for children of a certain age) Joey Deacon lived – the main thrust of his campaign was de-instutionalization and community care (and indeed, he got his wish). Similarly, there's another former Croydon mental hospital at Netherne-on-the-Hill, you can see the splendid water tower (now flats as part of the bigger estate that replaced the hospital) if you drive down the A23 towards the M25.

Possible there was a policy to put all the mental hospitals in Croydon. Or locally driven demand.

Epsom had similar. I believe that one in ten of the population was officially insane. Those institutions too are now all long gone.

And Banstead (closed 1986), which was so famous that Atomic Rooster wrote a song about it.  Hammond organ botherer and bipolar sufferer Vincent Crane had been a patient there.

The site is now occupied by a prison, which speaks volumes about the priorities of those in power ;)
