Bitcoin is plummeting, and it's dragging down other cryptocurrencies too

Bitcoin slumped as much as 17 per cent to $14,820, the most in more than two weeks

Bitcoin slumped, dragging down smaller rivals such as ether and litecoin, as concerns that regulators will tighten their grip on the market weigh on the world’s largest cryptocurrency.

Regulators in China and South Korea are increasing oversight on cryptocurrency trading and mining, while the US Securities and Exchange Commission late last year started cracking down on some digital token sales, known as ICOs. Coinmarketcap.com’s decision to exclude Korean pricing data for coins helped create the appearance of a large drop in prices, which some traders attributed as playing a part in the selloff.
