LONDON — The 10 biggest cryptocurrencies by market capitalisation were plunging Tuesday morning, with all suffering double-digit percentage losses.

Bitcoin fell as much as 16% in early trade, falling through both $13,000 and $12,000 levels, but has recovered slightly. The decline appears to have spooked the market, with other coins selling off at the same time.

Fawad Razaqzada, a market analyst with Forex.com, described the sell-off as a "cryptocurrency bloodbath" but said: "Suggestions that this is the start of the demise of cryptos is very premature."

Here's the scoreboard as of 2.o0 p.m. GMT (9.00 a.m. ET), per Markets Insider:

Bitcoin is down 15% against the dollar to $11,586.29;
Ethereum is down 17% against the dollar to $1,050.46;
Ripple is down 21% to $1.30;
Bitcoin Cash is down 21% to $1,877.15;
Cardano is down 22% to $0.62;

IOTA is down 19% to $2.91.
Cryptocurrencies have experienced a volatile start to 2018 after a huge rally last year.
