No they don't.

"They" can take 50% from you without even knowing who the fuck you are by doubling its supply on the ledger... Just push one lil button and wing-a-dingie-adee-ding, wam-a-dee-wee-woo-doodle.. and you have 50% less value than you had.   Easy ma peasie...

Note:  Relatively speaking, I largely agree with your overall point lightfoot, in regards to the preference of physical currency over some of the recent digital shenanigans in the makings.. but I also wanted to highlight a wee bit of an overstatement that seemed to have been contained within your own framing of current monetary money dynamics (fiat especially).


Is something missing, such as a link?  #justsaying
