Bitcoin hits fresh 2019 high as sudden rally shows staying power

Cryptocurrency traders may not know what caused the abrupt surge in Bitcoin on Tuesday, but they’re going along for the ride anyway.

The biggest virtual currency climbed to a fresh 2019 high on Wednesday, building on a spike yesterday that many market participants struggled to explain. Bitcoin increased as much as 5.9 percent to $5,087.54 at 11:10 a.m. in Hong Kong, according to Bloomberg composite pricing. Rivals coins including Ether and XRP also advanced.

With the Bloomberg Galaxy Crypto Index now up more than 77 percent from its low during the depths of last year’s crash, the debate over whether virtual currency prices have bottomed is heating up.
