It's issued by a central authority.
It represents a claim for a basket of fiat currencies.
That central authority dictates to everyone what they can and cannot buy with bitcoin.
That central authority dictates with whom you can trade bitcoin.
Everyone using bitcoin obeys those rules.
A bitcoin transaction takes several days.
Nobody is using bitcoin for anything apart from storing value.
Its supply is variable.
Great analogy!
It's SDR *for the little guy* as I said. Nation States of course use rules and regulations applicable to their real and present circumstances. Y'know, the circumstances of relevance and importance to people and organizations that actually have any bearing on consensual financial reality outside of these forums.
However, in effect the bitcoins are a very SDR-esque wanna-be reserve currency.
Analytically, Bitcoin is literally nothing more than a basket of fiat currencies, and always will be.
All the other super-fantastic anarchocryptojerkoffism is really inconsequential and over-rated in the end-game analysis. Furthermore, withjust a tad more effort than I care to put forth to take the piss out of you, it can easily be demonstrated that bitcoin has become centrally regulated ipso facto, by naturally emergent circumstances in a number of ways.
