Can I buy a pizza with it or pay my bills with it? Can my employer pay me in it? Or is it just an “emperor’s new clothes” thing? I just don’t see the tangible value in it. Rhetorical questions, BTW, I know you can’t buy a pizza with it, at least outside of some edge cases that I’m not aware of.
I thought what made money money was everyone agreed it was valuable and was willing to exchange it for goods and services directly. I don’t see that with crypto.


Well, you presumably believe that you know what you’re talking about, so why don’t you tell me how this tracing is supposed to work?
I create a fresh wallet A. I go to John and buy bitcoin with cash, deposited to that wallet. John knows zilch about me other than that some person occasionally shows up with cash, among dozens other people.
John gets busted, his wallets are known.
How does the FBI tie wallet A to me?
