As Bitcoin ETF nears, analysts warn of trading frenzy

If the Securities and Exchange Commission approves a bitcoin exchange-traded fund next month, it might set off a speculative rush into bitcoin.

Indeed, what some see as a chance for average investors to participate in one of the great financial innovations of recent years could set off a trading frenzy in an already wild market.
