Bitcoin is approaching bear market territory as the world’s largest cryptocurrency plunged almost 20 percent in less than two weeks.

The crypto was down more than 5 percent Friday morning from a day earlier and was last seen trading at about $56,600 per coin, about 18 percent below its peak of $69,000 reached earlier this month.

The price of bitcoin has now been on the decline for six straight days, and the downturn extends widely across cryptocurrencies.

Ether, the native currency of the Ethereum blockchain and the second-largest crypto, has similarly fallen about 15 percent from its peak of almost $4,860 per coin.
