Bitcoin slid to $10,000 on Wednesday for the first time since Dec. 1, leaving the cryptocurrency down by close to half from its peak hit last month.

Bitcoin, the largest and most prominent cryptocurrency, fell more than 11 percent to hit $10,000 on the Luxembourg-based Bitstamp exchange, amid worries about a regulatory clampdown.

The cryptocurrency touched a peak of almost $20,000 in December and indeed crossed over that threshold on some exchanges – but has since been roiled by several large sell-offs.

Bitcoin’s slide triggered a selloff across the broader cryptocurrency market, with biggest rival Ethereum down 23 percent on the day at one point, according to trade website Coinmarketcap and the next biggest, Ripple, plunging by as much as a third.
