of course, those who bought bit coin a year ago have lost 76% of their money ... some “investment”, hey?
Your mental habit of defining “money” as a particular national fiat currency is somewhat arbitrary. Actually they still have their bitcoins (unless they lost the key), so they haven’t lost any money. They may have lost 80% of their purchasing power in the past year, but that’s a different matter.
And those who bought in 5 or more years ago are multi-millionaires.
