Bitcoin recovered part of its Thursday decline late in the U.S. session after briefly dropping below $81,000, while stocks, bonds and commodities moved sharply in response to a mix of interest-rate pressure, elevated oil prices, technology concerns and renewed anxiety about cryptocurrency security. According to CoinDesk, bitcoin was trading near $81,800 as stocks closed, limiting its 24-hour decline to about 2% after a substantially weaker move earlier in the day.
Bitcoin’s sell-off eases, but broader crypto remains under pressure
Bitcoin broke below $82,000 for the first time since Sept. 20 and briefly moved under $81,000, its lowest level since Sept. 21. The decline came after bitcoin had traded close to $87,000 just four days earlier. Ether and XRP each fell about 6% over 24 hours at one stage, while solana dropped roughly 9%; all three were down by double-digit percentages over the previous week.
The weakness arrived as the anniversary of the Oct. 10, 2025, flash crash approached. In that episode, bitcoin fell from around $122,000 to $105,000 or lower on some exchanges after reaching a record above $126,000 only days earlier. The comparison added to market anxiety, although it did not establish that a similar event would occur.
Investors were also responding to higher oil prices, rising borrowing costs and uncertainty over U.S. cryptocurrency legislation following the failure of the Clarity Act. The U.S. midterm elections were another factor cited in the market discussion because their outcome could alter the balance of power in Washington.
Bitcoin’s move below $81,000 temporarily left approximately 6.4 million BTC held at a loss, according to Glassnode data cited in the report. Around 13.7 million BTC remained in profit, more than twice the amount underwater. These figures describe the price levels at which coins were last moved; they do not measure losses actually realised by holders.
Cryptography fears meet a pushback from specialists
One source of selling pressure was concern over claims that artificial intelligence could soon undermine the cryptography used to secure major digital assets. Justin Drake urged the blockchain industry to enter “bunker mode” and advised holders to move funds to addresses that had never signed a transaction.
Yehuda Lindell, Coinbase’s head of cryptography, rejected that warning. He said there was no evidence that the long-standing assumptions behind elliptic-curve cryptography had been broken. Lindell argued that a genuine breakthrough would have consequences extending beyond crypto, including the security of websites, banking applications and other digital systems.
The dispute illustrates how unverified technical claims can affect markets even when specialists challenge them. The source material describes the warning as fear, uncertainty and doubt, rather than presenting evidence that the cryptographic systems used by bitcoin or ether had actually been compromised.
Rates, oil and technology drive wider market volatility
U.S. Treasury yields initially surged before reversing lower. The 10-year yield had reached 5.36%, described as a multi-decade high, but later stood at 5.22%, down 5.5 basis points on the day. The 30-year yield touched 5.73% before falling to 5.60%, also down 5.5 basis points.
Earlier pressure on risk assets came alongside a stronger dollar and a jump in energy prices. WTI crude rose as high as $93 a barrel, while Brent reached about $105. The move followed a tanker attack off Qatar. Brent’s premium over WTI reached approximately $12.50, with prices around $105 and $92.50 respectively. The spread reflects the differing exposure of the two benchmarks to international shipping and supply conditions.
The technology sector also weakened after reports raised questions about OpenAI’s revenue figures. The Financial Times reported that the company had recently told investors annualised revenue was approaching $50 billion, below earlier reports of about $70 billion. The figures are not directly comparable: CNBC reported that the earlier estimate included revenue-sharing arrangements involving cloud providers, while the FT figure excluded those sales.
The Nasdaq fell as much as 1.3% before narrowing its loss. Nvidia, Broadcom and Micron were among the AI-related companies down by roughly 3% to 5%. Data-centre companies with cryptocurrency-mining backgrounds suffered heavier declines: Hut 8 fell 10.7%, Riot Platforms 8.8%, IREN 7.6%, Cipher Mining 9.1% and TeraWulf 6.4%.
Investor concerns also surrounded the proposed Australian listing of Firmus Grid. Backed by Nvidia, the data-centre company sought to raise as much as $5.5 billion at a valuation of $30.4 billion. Bloomberg reported that its order book closed as scheduled, but weak demand raised doubts about whether the offering would proceed. The concerns followed the postponement of SoftBank’s SB Energy IPO last month.
Market picture and the longer-term institutional view
At 21:39 on Oct. 8, 2026, Moneyiar data showed Bitcoin at $81,671.135080233, down 1.88% over 24 hours and 3.36% over seven days. Cardano was at $0.233835385, down 7.83% over 24 hours and 4.61% over seven days. ONEchain stood at $0.1323703988, down 4.09% and 4.08% over those periods, while Ark was at $0.2237517952, up 4.79% over 24 hours but down 6.33% over seven days. These are Moneyiar market data at that stated time.
Despite the immediate sell-off, a State Street survey of 300 asset managers, asset owners and wealth managers found that 51% expected digital assets to become mainstream within five years, compared with 11% in 2024. Respondents reported holding an average of 11% of their portfolios in digital assets and expected that share to increase over the next three years.
That contrast captures the market’s current tension: prices were under pressure from macroeconomic and sector-specific shocks, while the survey pointed to stronger institutional confidence in digital assets’ longer-term role. The survey does not remove the risks highlighted by Thursday’s trading, but it shows that short-term volatility and longer-term adoption expectations can coexist.
