It doesn't matter what the ethos behind Bitcoin is, if the market uses it like an investment just like stocks, then that's what it is, and that's how it will behave.
There’s no rhyme or reason to this, Bitcoin is in flux just like everything else.
The first is that investors requiring cash to cover margin calls for all the other markets that are tanking. This is likely to be a reason for the big drop in gold prices yesterday.
The second is a general flight to quality as evinced by the drops in Treasury yields in US, UK and Germany.
Or it could be wibble. It's crypto so we'll never actually know.
Also could be due to leverage trading becoming super popular the past year or two.
You can see a similar thing with Gold, and gold miners as well.
