The value of Bitcoin has plummeted so far this week, driven largely by Chinese regulatory action that now includes a pending ban on cryptocurrency exchanges (following an earlier ban on initial coin offerings). Then there also were comments from J.P. Morgan boss Jamie Dimon, who called it a "fraud" and said he'd fire any bank employee "stupid" enough to trade bitcoin.
