The price of ether also dived to a low near $3,500 on Saturday. It recovered a little by Saturday night, trading at $4,233. Ether, the world's second-largest digital coin by market value, lost more than 16% from Friday morning around 8 am ET through to Saturday 8 am ET.
Crypto began falling Friday as stocks pulled back and investors fled to the safety of Treasuries, pushing the 10-year yield lower. Risky tech stocks were among the biggest losers on Wall Street on Friday, with Tesla shedding 6%. The ARK Innovation fund lost 5% on Friday and 12% on the week.
As the sentiment soured in the tech space, those investors may have also started unloading their crypto.
But there was no clear reason for the cryptocurrency drop, especially overnight Saturday when the losses accelerated.
"The evidence points to this being yet another derivative-induced selling event," wrote J.C. Parets, chief market strategist for All Star Charts technical research, in a note Saturday morning. "The September flash crash had the same drivers as this selloff — leverage was flushed from the system in a violent fashion, which later enabled the market to eventually move higher toward a new all-time high in October."
Will Clemente, insights analyst at Blockware Solutions, agreed that the sell-off was derivatives-based and added that open interest has been at all-time highs for more than a month while funding rates have been positive. He also said it could be the set-up for another bull run like the one that kicked off this year.
"There's a reasonable case that we could see the opposite effect heading into Q1, as funds are willing to take on more risk for the new year with fresh profit and loss," he said. "This effect assisted in bitcoin's massive move in January 2021."
He added that, network dynamics are still "healthy and show supply continues to move to long term investors."
Both cryptocurrencies have experienced turbulent trade since the omicron Covid variant emerged, tracking global stock markets which have been also volatile. On Nov. 26, bitcoin hit a seven-week low close to $54,000, officially entering bear market territory.
Bitcoin is now down about 30% from an all-time high close to $69,000, which it hit in early November. Bear markets are typically defined as a decline of 20% or more from recent highs.
The World Health Organization on Friday said the Covid omicron variant has been detected in 38 countries, up from 23 two days ago, with early data suggesting the strain is more contagious than delta.
Parets noted that the coming days and weeks are expected to bring "choppy" price action. "A contraction and basing process is likely to take place after such a violent move and we want to treat sharp upward rallies suspiciously right now," he said.
Fairlead Strategies' Katie Stockton said that long-term momentum is still moving upward despite the correction. She cautioned investors against reducing holdings of bitcoin or other correlated altcoins until a breakdown is confirmed — which could mean waiting until Monday to reassess.
"It is rarely a good idea to sell into an emotionally-charged downdraft like this given the possibility of a shakeout," Stockton said. "A close above $48,000 tonight would be an incremental positive based on the current high-low range."
