Bitcoin is back above US$10,000 (NZ$15,630).
The largest cryptocurrency's recent upward momentum carried it past that psychologically significant level Sunday for the first time since October, according to Bitstamp pricing. It rose as much as 2.6 per cent, to US$10,179, capping a gain of about 40 per cent so far this year.
Its breach of five figures comes amid an equities rally that's seen the S&P 500 Index reach new highs as fears abate that the coronavirus will dent global growth.
"The rally is a part of a broader appeal for risky assets as optimism grows that the coronavirus impact might be limited to the first quarter and on optimism that China will play nice with the US on phase-two trade talks," said Ed Moya, senior market analyst at Oanda.
Cryptocurrencies have been on an upward trend all year, with some analysts and digital-asset enthusiasts suggesting they've benefited as safe-haven plays amid ongoing geopolitical concerns around the globe.
