Being digital, Bitcoin has some nice properties that precious metals don't, but we stopped using precious metals as the foundation of the economy decades ago. The idea remains popular with a certain set of ideologues who want to make their cash holdings the basis of the financial system, but that's much too inflexible to run a modern economy.
Economists overwhelmingly believe that they need currency control to manage irrational market speculation. Technologists frequently cite a small number of economists who disagree, and while truth is not a democracy, but it's wise to be suspicious when one's choice of experts just happens to affirm the things that benefit you personally.
tl;dr: There could be a place for blockchain, but BTC is based on a bunch of self-imagined revolutionaries who don't know how to manage an economy.
Stocks are feeling more and more like this also.
