Ether, the world's second-largest cryptocurrency, hit an all-time high on Wednesday, catching up with bitcoin's rally and riding on news of wider blockchain adoption.
The ether token, which underpins the ethereum blockchain network, rose as high as US$4,670.81, as of 3.15pm EDT.
The cryptocurrency extended its gains, breaching the previous day's US$4,600 level, after the US Federal Reserve announced a tapering of its asset purchases, but held to its belief that high inflation would prove "transitory" and likely not require a fast rise in interest rates.
Ether is up more than 10 per cent this week.
In the days since bitcoin, the world's largest cryptocurrency, hit its record high of US$67,016.5 on Oct 20, other tokens on the base layer of blockchain networks, known as Layer 1 networks, have gathered momentum.
"The correlation of crypto versus equities and risk-on sentiments is high," said Danny Chong, chief executive officer of decentralised asset tracking platform Tranchess, who expects further gains over the quarter.
"Everyone is expecting a bull run with the absence of negative news," said Chong. "To decide the depth of the move, one should ask what can bring it down?"
Bitcoin (BTC) was trading around US$63,262 and is up about 117 per cent this year, while ether is up sixfold.
"Since the market reversal at the end of September, ether's strength has been moving in stride with BTC and other majors," said Ryan Rabaglia, managing director and global head of trading at digital asset platform OSL.
"Ethereum has been the clear winner of the Layer-1s for what we believe will be a substantial shift in a potentially prolonged market sentiment uplift. Ethereum will also continue to play a major role in the NFT and metaverse ecosystem build- out," he said.
The steady stream of news on cryptocurrency adoption by banks, growth of nonfungible tokens on virtual gaming platforms, launch of bitcoin futures-based US ETFs and a need among investors for diversification in an uncertain interest rate environment have pushed several blockchain tokens, including bitcoin and ether, higher since October.
Smaller tokens, too, have attracted interest after Facebook rebranded itself as Meta to focus on building the "metaverse," a shared virtual environment.
Australia's largest bank, Commonwealth Bank of Australia, said on Wednesday it will become the country's first to offer retail clients crypto services.
According to digital assets researcher CryptoCompare, assets under management (AUM) in digital investment products rose 45.5 per cent in October to a record high of US$74.7 billion. The total AUM for bitcoin-based products grew 52.2 per cent to US$55.2 billion, while ethereum-based funds AUM increased 30 per cent to US$15.9 billion, record highs for both categories.
