Classic FUD article by someone who doesn't understand Bitcoin.
"Not a store of value because it has too much value in of itself."
What kind of logic is that?
"It is not much use as a medium of exchange because it is not even now widely accepted"
We are barely into the early adoption phase of Bitcoin, and it is already being used globally. More so is some places than others. Mainstream recognition of Bitcoin is just beginning.
The volatility is there of course because the market is still very small and susceptible to manipulation by whales. Once the market reaches into the trillion dollar range stability will manifest.
