Bitcoin smashed through the $5,000 (actually over 5,100) barrier for the first time ever on Thursday, jumping as much as 7 percent to chalk up its biggest daily rise in over two weeks.
Bitcoin, the original and still the biggest cryptocurrency, has been on a tear recently, rallying 75 percent in barely a month.
It has chalked up a more than fivefold increase in price since the start of the year 2017.
