Bitcoin hits one-week low

Cryptocurrencies plunged on Monday, with bitcoin dropping more than 12% to a one-week low as rising U.S. bond yields lifted the dollar broadly and hurt other safe assets that pay no income.

Bitcoin fell as far as $33,447, its lowest since Jan. 6. Ethereum which often moves in tandem with bitcoin, fell as much as 20% to a one-week low of $1,007.51.

The falls are much larger than the 1% drop that sent gold prices to a one-month low, but reflect a wider dollar bounce against major fiat currencies as the prospect of higher U.S. interest rates tempers popular bets against the dollar.

Losses pared a little by lunchtime in Asia to put bitcoin at $35,192 – about 16% below a record peak of $42,000 which the world’s most popular cryptocurrency hit last week.

Interest in bitcoin has been soaring as institutional investors began buying heavily, viewing it as both an inflation hedge and as exposed to gains if it became more widely adopted as a digital currency.

J.P.Morgan strategists wrote on Jan. 5 that bitcoin has emerged as a rival to gold and could trade as high as $146,000 if it becomes established as a safe-haven asset.
