The price of bitcoin, the red-hot digital cryptocurrency, was trading down 7.2% on Friday afternoon, at $6,618 a coin.
That's down more than $1,000 from its all-time high of nearly $7,900 a coin, which it hit on Wednesday after news broke that a planned upgrade to the network had been called off.
But now money is pouring out of bitcoin and into bitcoin cash, the cryptocurrency that split from bitcoin in August.
Bitcoin cash soared to an all-time high of $1,009 a coin on Friday afternoon.
