Bitcoin hit a market capitalization of USD 1 trillion as it rose to yet another record high on Friday, countering analyst warnings that it is an "economic side show" and a poor hedge against a fall in stock prices.
The world's most popular cryptocurrency jumped to an all-time high of USD 56,399.99, posting a weekly gain of 14 per cent. It has surged nearly 70 per cent so far this month and was last up 8 per cent at USD 55,664.
Bitcoin's gains have been fueled by signs it is gaining acceptance among mainstream investors and companies, from Tesla Inc and Mastercard Inc to BNY Mellon .
All digital coins combined have a market cap of around USD 1.7 trillion.
"If you really believe there's a store of value in bitcoin, then there's still a lot of upside," said John Wu, president of AVA Labs, an open-source platform for creating financial applications using blockchain technology.
"If you look at gold, it has a market cap of USD 9 or USD 10 trillion. Even if bitcoin gets to half of gold's market cap, that's still growth of 4X, or USD 200,000. So I don't know when it stops rising," he added.
The next milestone will be overtaking Alphabet Inc , currently valued at USD 1.431 trillion, said Jacob Skaaning, portfolio manager at crypto hedge fund ARK36.
"There will likely be some big fluctuations along the way, but I'm still very bullish and I believe the uptrend will continue for the time being," he added.
Still, many analysts and investors remain skeptical of the patchily regulated, highly volatile digital asset, which is little used for commerce.
Analysts at JP Morgan said bitcoin's current prices were well above estimates of fair value. Mainstream adoption increases bitcoin's correlation with cyclical assets, which rise and fall with economic changes, in turn reducing benefits of diversifying into crypto, the investment bank said in a memo.
"Crypto assets continue to rank as the poorest hedge for major drawdowns in equities, with questionable diversification benefits at prices so far above production costs, while correlations with cyclical assets are rising as crypto ownership is mainstreamed," JP Morgan said.
Bitcoin is an "economic side show," it added, calling innovation in financial technology and the growth of digital platforms into credit and payments "the real financial transformational story of the COVID-19 era."
