LONDON: Bitcoin moved to within a whisker of its all-time high on Tuesday, after hitting $19,000 for the first time in nearly three years. The world's most popular cryptocurrency was last up 4.8% at $19,225, just shy of its all-time record of $19,666 hit in December 2017. Bitcoin has gained around 25% in the last two weeks alone, and is up around 160% this year.

Fuelling its rally have been demand for riskier assets amid unprecedented stimulus programmes to counter the Covod-19 hit; hunger for assets perceived as resistant to inflation; and expectations cryptocurrencies will win wider acceptance as a method of payments.

Bitcoin's 12-year history has been peppered with vertiginous gains and equally sharp drops. Its markets and price discovery is highly opaque compared with traditional assets such as stocks or bonds.

Analysts say bitcoin's limited supply of 21 million makes it a good hedge against inflation. Some investors think the value of traditional currencies will fall as governments and central banks unleash massive stimulus packages to support economies hit by Covid-19.

Yet bitcoin's gains have continued even as gold - traditionally a go-to hedge against inflation - has slipped, with a resurgent pandemic making global growth and inflation recovery a more distant prospect.

Gold has shed 3.6% this month, versus bitcoin's 40% gain. Bullish investors cited expectations that bitcoin would achieve mass use as a means of payment - something it has so far failed to do - as a reason for the divergence.
