Which I concur with. Cryptocoins are worthless, the idea Bitcoin has a market cap of $5-6 hundred billion is absurd, and maybe the increasing fed funds rate etc. will pop this speculative bubble more than it already has (Bitcoin had the even more absurd market cap of $1 trillion toward the end of last year).
Why is a Bitcoin worth anything? I know why my M1 Mac is worth something, I know why a box of raisins is worth something, I know why a bar of gold is worth something. I see no worth in a Bitcoin. I ask why it has any worth and the bag holders cast around looking for an equivalent, and only seem to find that dollars have been unmoored from value for half a century and the response is it's like the dollar (of course the dollar is implicitly, not explicitly like before 1971, backed by tens of thousands of tons of bullion gold among other things, but that's another tangent...)
