Bitcoin has surged past $US8,000, its highest level since July last year, as the cryptocurrency's rally gained further momentum.
There is no real fundamental explanation as to why bitcoin, the original cryptocurrency, hit a 10-month high on Tuesday morning (Australia time).
But there is an ongoing blockchain and cryptocurrency conference in New York called Consensus, with big investors and influential market players gathered to network and discuss the current state of the industry.
Bitcoin had also rallied during previous Consensus conferences.
At 1144 AEST bitcoin was trading for $US8,026 ($A11,538) on the Bitstamp exchange, up more than 11 per cent.

It hit a high of $US8,167.50 ($A11,742), a roughly 10-month peak.
Some analysts pointed out that bitcoin's rally coincided with the escalating trade war between the United States and China, which eroded overall market risk sentiment.
But it is too soon to declare bitcoin as a safe-haven asset, they said.
Fred Schebesta, co-founder of Sydney over-the-counter cryptocurrency trading desk HiveEx and who is currently speaking at the Consensus conference, said the "crypto winter" was finally over.
"This space isn't going anywhere. Confidence is slowly returning to the market," he said. "But we need more real world adoption for cryptocurrency to be widely used."
David Thomas, of London-based cryptocurrency broker GlobalBlock, said the breaching of a key $US6,000 support level last week fuelled interest among investors.
In addition, Lukman Otunuga, research analyst at FXTM, said the bullish "golden cross" is already in play on the daily charts.
This occurs when the 50-day simple moving average has crossed above the 200-day moving average.
Other market participants said perceptions of bitcoin's resilience in the wake of last week's $US40 million theft from the major Binance exchange was supporting sentiment.
Cryptocurrency markets have previously fallen after high-profile security breaches.
Bitcoin has almost doubled in price this year, underscoring its volatility after a bruising 2018.
Last year it lost some three-quarters of its value amid tighter regulation across the world.
But so far on the year, bitcoin has been up a sparking 119 per cent.
