Is there even any currency that meets that definition? Iirc even bitcoin had some kind of reversal back in the day, or am I misremembering? I seem to recall bitcoin splitting in 2 for a while as there was some disagreement on whether the reversal should be made or not.

Idk, it's been a while and my memory is fuzzy.

In a court of justice you'd be right, of course.

But for online armchair speculation, you have to admit it seems a likely explanation.

I mean they use Blockchain, right? Isn't that like the only real requirement for the name crypto?

As long as you burn as much electricity as Andorra does in a week just to make a transaction, you're probably a cryptocurrency. And that's their sole benefit it seems.
