A Central bank currency on the blockchain is just the same trash that is being printed every day. I always found it odd that the market "sells off" because of fears of inflation. What are you selling off to? Cash? Bizarre. And Gold and Silver is terribly suppressed. Worse, Gold supplies will magically tripple if the price goes up even slightly, suppressing the price. I do think there is a place for metals in every portfolio though.
Again, central bank crypto currency is the same garbage you have in your bank today, except now its on blockchain. What is unique about bitcoin is the lack of any "figurehead "or organization that could be singled out to hurt it. Satoshi is "probably" dead.
Every other crypto out there has either a central figure / organization, or an anonymous team that will do a rug pull.
Bitcoin is just one of the most interesting monetary human experiments that is just fundementally built on gameing the human psyche. The properties that are built into it are genius. Game theory is strong with this one. Just nothing like Bitcoin.
Is it worth what it is being sold for now? Who am I to say, let the market decide.
