These are well put. All those commercial and government projects seem
ridiculous. And the idea of investing in cryptocurrency seems as ridiculous as
investing in currency. Currency doesn't do anything by itself.
On the other hand there is no real argument here as to why cryptocurrency is
not a useful means of exchange, a currency. Except possibly the scalability
argument.
