NEW YORK (AP) — Bitcoin's public profile grew six months ago when the first exchange-traded product tied to it hit the market.

It took just two days for the fund, the ProShares Bitcoin Strategy ETF, to amass more than $1 billion. That’s even though the fund, which often goes by its ticker symbol BITO, doesn’t hold bitcoin itself. Instead it invests in futures for bitcoin, a regulated market where traders make bets on where the cryptocurrency is heading in the coming months.
