"One day everyone will use China's digital currency"
You think patriots would let that happen?
(Note that BtC has popped almost x6 since about the exact date this article was published last September. True, the fiat dollar bloated, but by nowhere near enough to justify even half of that move.)
Bitcoin is not scarcer than class-a or class-b stock, or corporate bonds, or class-c "common" shares of delisted husks, nor is it scarcer than antiques and other rare-artifact numismatics (all of which are far better "stores of value" than crypto, and insurable to boot). Nobody ever worries about Ferarris made in the 1960s suddenly plunging in value 40% overnight. Last of all, it's not scarcer than real-estate.
Yes, it's portable -- but only a tiny sliver of people currently in BtC use it for the express purpose of transporting wealth in a personal carried flashdrive wallet. The vast majority of hodlers are Coinbase and Binance speculators.
yes it is.
