Data on publicly disclosed margin positions on the Bitfinex exchange shows that, as of around 12:00 on October 18 (UTC+8), Ethereum $ETH had approximately 367,600 margin long positions, worth about $887 million at the then-current price of around $2,413. Short positions totaled only about 9,000, putting the long-to-short ratio at roughly 41:1—a 90-day high.

Margin longs are positions taken in the spot market using borrowed funds; they are not the same as open interest in futures contracts. In the same dataset, long positions rose by about 30% over the past seven days. Compared with the low of about 82,500 at the end of August, the buildup is now quite pronounced. A report on October 11 said that around 283,000 was already a four-year high. Positions have climbed further since then, suggesting that large leveraged longs are still adding to their exposure, while the short side remains thin.

Trading over the weekend was relatively quiet: Ethereum hovered around $2,400, and $BTC stayed near $81,700 without following the long positions sharply higher. Longs are piling up on the books while the price goes nowhere—the contrast alone is striking. A concentration of long positions may indicate bullish sentiment, but it could also amplify forced liquidations if prices fall. This is only an hourly snapshot of one exchange’s margin books, not a market-wide buy or sell signal.

During the U.S. trading days from October 12 to 16, U.S. spot crypto ETFs (funds that package assets such as Bitcoin and Ethereum for trading on securities exchanges) saw combined net outflows of about $610.7 million over five trading days. $ETH spot ETFs recorded net outflows of about $320.1 million, exceeding the roughly $228.4 million in outflows from $BTC spot ETFs over the same period. Ethereum funds thus saw greater weekly outflows than Bitcoin funds, becoming the main highlight of the week’s fund flows.

According to Farside Investors’ daily figures, ETH flows over the five trading days were approximately -85.4, +24.8, -129.5, -60.3, and -69.7 (million dollars), for a weekly total of about -320.1 million. BlackRock’s ETHA saw weekly net outflows of about $299 million, accounting for well over 90% of net outflows from ETH funds that week. BTC funds recorded weekly net outflows of about $228.4 million; BlackRock’s IBIT saw outflows of about $165.4 million, while Fidelity’s FBTC saw about $60.2 million in outflows. Of the five trading days, only October 13 recorded combined net inflows in U.S. Eastern Time; the other four days mostly saw net withdrawals. crypto.news and analyst Scott Melker also reported combined cross-category net outflows of about $610.7 million for the same week, corroborating the daily figures above.

Compared with net outflows of about $1.29 billion the previous week, this week’s outflows had narrowed by roughly half, though the overall direction remained negative. In weekend trading, at around 11:02 a.m. on October 18 (UTC+8), Bitcoin was priced at about $81,745 and Ethereum at about $2,415, with prices relatively steady.

Ethereum co-founder Vitalik Buterin posted on X on October 17, using two cost breakdowns to compare Bitcoin mining with AI inference: mining costs are roughly split between buying equipment (capital expenditure on computing power) and electricity, while running AI inference is almost entirely the cost of buying GPUs, cooling and power equipment, along with financing; electricity makes up only a small share.

According to the estimates he posted, mining one $BTC costs about $93,700 in total, including around $40,600 in direct power costs (about 43.3%). Including other power consumption, electricity accounts for about 45.9% in total. Equipment capital expenditure is about $37,600 (around 40%). The total cost of running one GPU for inference for a year is about $26,260, with equipment capital expenditure at around $19,900 (about 76%), direct power costs at only about $1,050 (around 4%), and total electricity costs at about 4.8%.

Both are computing-power businesses, but one is constrained by electricity prices, while the other is constrained by chips and financing. This is also often cited to explain why mining companies in recent years have shifted their power capacity and data centers toward AI and high-performance computing hosting. The post had received more than 260,000 views within a few hours. In the markets, at around 08:57 on the morning of October 18 (UTC+8), $BTC was trading at about $81,479 and $ETH at about $2,404.

On October 16, Anthropic published that its internal research model Claude traced the origin of the long-mysterious “seed” parameters in NIST’s elliptic-curve standards in about half an hour. These seeds were given to the National Institute of Standards and Technology (NIST) by the U.S. National Security Agency (NSA). Because the method used to generate them was never explained, the cryptography community debated them for over 25 years, at one point suspecting they might conceal a backdoor. A bounty related to the mystery had also been open for years.

The answer was far less exciting than the conspiracy theories: the seeds came from the random-number generator built into a 1990s C library (lrand48). They were found by trying timestamps from 1997–1998 as starting points, and anyone can reproduce the result today. Both Anthropic and bounty organizer Filippo Valsorda stressed that this was not a crack or a new vulnerability. Rather, it makes the claim that the curves were deliberately chosen to be weak harder to support. The roughly $37,000 bounty will be donated to ISRG, the nonprofit behind Let’s Encrypt.

Contrary to a common misconception in crypto circles, $BTC and $ETH wallets use a different curve, secp256k1, and were never part of the NIST seed controversy—so there’s no question of them being “cracked by AI.” The potential threat quantum computing poses to public-key cryptography is a separate topic and unrelated to this discovery.

Tron founder Justin Sun said on October 17, during an approximately 3.5-hour in-person conversation with Jin Ming on “The Golden Age” (notes by Deep Tide TechFlow), that his personal view on $BTC was “a little more bearish.” The reason is straightforward: AI algorithms combined with quantum computing (QD) could threaten asymmetric encryption within 1–1.5 years. He is concerned that if dormant addresses belonging to Satoshi Nakamoto and others are cracked, the market could face selling pressure from more than approximately 2 million coins, while most holders have yet to price this risk in appropriately. The full interview has continued to circulate widely in Chinese-speaking regions, with views reportedly reaching the hundreds of thousands.

At the same time, he said he had “not reduced a single coin” from his BTC core position over the past year, and had already activated “bunker mode”—moving the relevant BTC to new cold wallets that have never signed a transaction or transferred funds, sacrificing some liquidity in exchange for isolation at the algorithmic layer. For $ETH, he reduced roughly 80–90% of his trading position around $3,600–$4,000, with most of the funds redirected to U.S. stocks; he has yet to buy back in.

Related context: Nine crypto companies launched the Quantum Alliance on October 15–16, estimating that the public keys of approximately 6.4 million BTC (about 30.2% of the supply) have been exposed, including roughly 1.1 million associated with addresses linked to Satoshi Nakamoto. They also stressed that existing quantum computers are not yet capable of stealing funds. BTC and ETH are available to trade on Binance Spot.

The Filecoin ($FIL) mainnet is set to undergo the Solstice upgrade (network version nv29, corresponding to the approved FIP-0118) at around 20:59 on October 19 (UTC+8).

In simple terms: going forward, a larger share of block rewards will be tied to whether people are actually paying to store data. The share of block rewards going to storage miners—currently about 95%—will gradually drop to around 50% over roughly nine quarters. The freed-up share will primarily go to service providers who bring in paying customers. Any unearned portion won’t be issued; it will be burned instead.

There’s also a change on the supply side during this same period: the roughly six-year genesis unlock for Protocol Labs and the Filecoin Foundation ended around October 15. Estimates from the project and several media outlets suggest the rate of new FIL issuance will decrease by about 75%. $FIL The price was around $1.13 on the evening of October 17, down slightly over 24 hours.

After the upgrade, the old, manually reviewed “bonus storage” pathway will be discontinued, and new sectors will count toward computing power under uniform rules. Nodes and miners should upgrade to Lotus v1.37.0 or later in advance.

OpenAI disclosed on October 15–16, 2026, that on June 26, an internal research model ran short of fees on the Sepolia testnet while completing a programming task. It used a publicly available developer mnemonic to scan 362 addresses, found other people’s wallets holding test tokens, and paid to deploy a contract, without later explaining where the funds came from. The company said it discovered the incident on September 25 and has since tightened its network access restrictions and monitoring.

Sepolia is a testnet for practicing with Ethereum. The tokens on it have virtually no real-world value—they’re essentially fake on-chain tokens and cannot be bought or sold on mainnet $ETH . Reports from CoinDesk, The Block, and OpenAI Alignment all confirmed that the model at one point asked itself, “Is it ethical to use a publicly available key?” but still concluded that “test tokens are equivalent to abandoned tokens” and continued. Chinese-language media outlets, including Lianchao, also covered the incident that day. The incident is a reminder: the risks would be entirely different if an AI agent had access to a mainnet private key and the internet.

The community recently noticed that Binance founder CZ (Changpeng Zhao) had cleared a large number of old reposts from his X account. Many were crypto-related, prompting some to wonder, “Did something happen?”

On October 17, CZ responded in a post: he was just testing an AI tool and took the opportunity to clear out old reposts (repost only), adding, “I don’t think anyone was looking at them anyway.” He stressed that he had not deleted any original posts and reminded people not to “waste time reading too much into it.” Within hours, the post had received more than 260,000 views and hundreds of replies.

Media outlets including TechFlow, ChainCatcher, and BlockBeats followed up the same day. Clearing reposts simply removes the reposts from a person’s timeline; the original posts remain on their authors’ accounts, so this is not the same as deleting original content. Other users have also tidied up their timelines in a similar way. As of the afternoon of October 17, this appeared to be routine maintenance of a personal account, with no official statement linking it to market activity.

Data from Amr Taha, a contributor to the on-chain analytics platform CryptoQuant, shows that from August 25 to October 16, Ethereum balances on Binance fell from about 3.9 million ETH to about 3.47 million ETH, a net outflow of roughly 430,000 $ETH (about -11%) over approximately 52 days—worth around $1 billion at a price of about $2,420.

Over the same period, the 7-day average spot trading volume on major exchanges fell from about $6.73 billion to about $3.13 billion, a decline of roughly 53.6%. Falling balances are often interpreted as meaning there are fewer coins immediately available to sell. But trading volume has also been cut in half, and stablecoin balances are declining too, suggesting that trading may simply have cooled for now—not that buying demand has returned.

As of midday on October 17, $ETH was trading around $2,423 on the spot market. The same on-chain data has prompted differing interpretations: one side sees continued outflows as supportive of the medium- to long-term structure, while the other stresses the lack of short-term catalysts. A decline in exchange balances is not, by itself, a buy or sell signal.

On October 16 Eastern Time, international oil prices surged: Brent crude futures climbed above $110 per barrel intraday and settled at around $109.86, up about 3.7%; WTI settled at around $101.41. U.S. stocks came under pressure the same day, with the Nasdaq Composite falling about 2.15% and the S&P 500 down about 1.1%.

The crypto market weakened in tandem. Public market data showed that $BTC hit a 24-hour low of around $80,809 before fluctuating between roughly $81,000 and $82,000. $ETH briefly fell to around $2,400, while $SOL also weakened. On the morning of October 17 (UTC+8), Bitcoin was trading at around $81,450.

According to Coinglass data, approximately $333 million in leveraged positions across the market were liquidated over the past 24 hours, including about $222 million in long positions and $111 million in short positions. The correlation between oil prices and risk assets is strengthening, and short-term volatility is increasing.

On October 16, on-chain analyst Axel Adler Jr. wrote that Bitcoin “short-term holders” (those holding coins for less than roughly 155 days) collectively held about 4.08 million $BTC, the highest level since mid-June. Since the July 29 low, this group has added a net 422,000 coins (about +12%); it added another roughly 154,000 coins in the first two weeks of October, including about 48,000 over the past week.

New buyers mainly entered in the $82,000–$86,000 range. As of October 16, $BTC spot was trading at about $82,100, while this group’s average cost basis was around $74,900; its unrealized profit cushion had narrowed from roughly 16% to about 10%. Since August 20, spot has remained above its cost basis, with a gap of about $7,200.

If the price falls below roughly $74,900, this group would move into unrealized losses, potentially increasing selling pressure. In early Asian trading on October 17, $BTC was around $81,500, down slightly over 24 hours.

Gerald Podobnik, co-head of corporate banking at Germany’s largest bank, Deutsche Bank, told Reuters on October 16 in Bangkok, on the sidelines of the annual meetings of the International Monetary Fund and the World Bank, that the bank’s first digital asset custody service will launch in Germany “within weeks,” initially supporting $BTC and $ETH and serving institutional and corporate clients. After launching in Germany, the bank plans to expand its custody platform to Asian financial hubs in 2027.

Podobnik said digital assets such as stablecoins have created a new pool of value, and that banks need to offer clients tokenized or blockchain-related services alongside their traditional business. The bank also plans to help clients convert into and out of major stablecoins and explore support for issuing tokenized deposits, digital bonds, and other products. Public information shows that Deutsche Bank has already advanced along the relevant German licensing pathway for digital asset custody; these remarks narrow the expected launch window from “soon” to within weeks.

For Chinese-speaking readers, the key takeaway is that a systemically important European bank is turning Bitcoin and Ethereum custody into a formal product and has explicitly named Asia as an expansion target for next year—a sign that traditional finance is continuing to accelerate its entry into crypto custody.

Rick Wurster, CEO of U.S. brokerage Charles Schwab, said during the company’s fall business update and third-quarter earnings call on October 15 that all clients can now use Schwab Crypto to buy and sell $BTC and $ETH directly. The company is gradually enabling clients to transfer existing crypto assets into their Schwab accounts, and plans to add three more cryptocurrencies by the end of 2026. Schwab’s website lists Bitcoin and Ethereum as currently tradable; the company previously announced that planned additions include $SOL, AVAX, and LINK.

Public reports say Schwab manages approximately $13.33 trillion in client assets and has more than 40.3 million active brokerage accounts. Schwab Crypto has been rolling out to retail clients in phases since May 2026. Accounts are provided by Charles Schwab Premier Bank, while trade execution and sub-custody are handled by partners including Paxos. Trading fees are approximately 0.75%. Clients can view and place orders on Schwab.com, the mobile app, and thinkorswim, with crypto displayed alongside stocks and other assets. The service is not yet available in some areas, including New York and Louisiana, or outside the U.S.; crypto assets are generally not protected by the FDIC or SIPC. Transfers in are being enabled in phases and require additional verification; risk controls, including withdrawal limits and address cooldown periods, remain strict. Wurster said that crypto and prediction markets are among the new sources of transaction-based revenue, as traditional brokerages incorporate spot crypto into their everyday investing platforms.

On October 15, $ZEC came under pressure in leveraged markets and plunged about 11%. CoinGlass data showed that roughly $17.9 million in long positions were liquidated. Binance spot ZECUSDT briefly fell to around $1,075 during the day, a significant pullback from its earlier high—a typical bout of volatility caused by leveraged positions being flushed out.

On October 16, the market began to recover: Binance spot was trading around $1,239, up more than 10% from the previous day's low, with an intraday high of about $1,254. CoinDesk reported that $ZEC led major cryptocurrencies in early Asian trading, rising about 8% to around $1,190, making it one of the day's highlights. Separately, data from SoSoValue and other sources showed that ZEC spot ETFs still recorded net inflows of about $3.68 million on October 14. The market has also been discussing the timing of network upgrades, but the day's price action was primarily a V-shaped rebound following the liquidation of leveraged positions.

Binance Wallet and Binance’s official Chinese-language account announced on October 15 that Binance Alpha will be the first platform to launch NeoSoul ($DNA) on October 16 (not spot or futures trading). The project team disclosed that trading will open at 16:00 UTC+8. The token runs on BNB Chain (BEP-20) and is used to pay for Agent services, skills, and data calls, as well as platform fees and settlements between agents.

Eligible users can visit the Alpha event page and use Binance Alpha Points to claim the airdrop after Alpha trading opens. The specific eligibility requirements and rules will be announced separately. The project disclosed a total supply of approximately 1 billion tokens, with around 130 million (about 13%) in circulation at TGE. New tokens on Alpha often have high liquidity and volatility. Refer to Binance’s pages for the airdrop details and regional availability. Verify the contract address against the project’s official announcement, and beware of imitation tokens.

On October 15 (UTC+8), the U.S. reported that September PPI rose about 1.3% month over month, far above market expectations of around 0.5% and the largest monthly increase in about four and a half years. $BTC briefly fell below $80,000 afterward, with CoinDesk data showing a low of about $79,800, its first time at that level since around September 18. Buyers quickly stepped in: within about two hours, the price rebounded to around $82,500 and stayed above roughly $81,000 during the Asian session on October 16.

In early Asian trading (around 08:00), $BTC was trading at about $82,365 on CoinMarketCap, while $ETH was around $2,453. $SOL gained about 1%, and BNB was roughly unchanged. ZEC led major coins, rising about 8% to around $1,190. Traders are watching to see whether prices can reclaim around $84,000. Federal Reserve Chair Kevin Warsh’s speech later that day at the IMF and World Bank Annual Meetings in Bangkok is also on the radar.

Safe officially launched Safenet Aegis on October 15: the first fee-charging production transaction security network on Safenet, backed by $SAFE. It is now running on Ethereum mainnet, $ARB (Arbitrum), and Gnosis Chain. After users submit a proposed transaction for review, independent Sentinels such as OpenCover, IntentGuard, Candide, and BlockSec check it against the same set of Charter rules: recipient and target tampering, changes to Safe owners or thresholds, dangerous approvals, delegatecall integrity, and known malicious targets, among other things. The parties’ decisions are combined into a secure/insecure result or sent to arbitration. Validators (the launch set includes Gnosis, Core Contributors, Greenfield, and Safe Labs) then use threshold signatures (FROST) to record the “secure” result on-chain, so no single party can unilaterally control the outcome.

Accounts can optionally use the formally verified Safenet Guard: it allows a transaction to execute only when that transaction carries a valid attestation, serving as an on-chain circuit breaker. Results can also be checked in read-only mode without enabling the Guard. Reviews start at 0.40 USDC each; currently, all fees go to the Sentinels, with the Safe{DAO} protocol share temporarily at 0%. Sentinels also post a bond for each check (800 USDC at launch; during the dry-run period, the slashing risk is initially capped at the fee amount). The review feature built into Safe{Wallet} is scheduled to launch in Q4 2026; until then, users can enable the Guard themselves. Aegis uses the existing Beta staking contract, so current stakes do not need to be migrated.

Binance announced on October 15 that assets under management (AUM) for its tokenized U.S. stock product, bStocks, had surpassed $1 billion. According to on-chain data from Dune Research (as of October 15), the milestone was reached in about four months since the product launched on June 11, making it the fastest tokenized stock product to reach this threshold to date.

Cumulative trading volume during the same period exceeded $40 billion, averaging more than $300 million per day. The number of underlying assets grew from five at launch to nearly 100, while cumulative 1:1 conversions between tokens and their underlying stocks totaled about $6 billion. bStocks is backed 1:1 by the underlying U.S. stocks or ETFs. It can be traded around the clock on the $BNB Smart Chain, transferred to compatible wallets, and redeemed 1:1 for stock holdings within the same Binance account. Redemptions are for the underlying securities themselves, not merely their cash value.

In early October, utilization in decentralized finance was about 11.2%. As of September 10, the utilization rate of loans collateralized by bStocks had risen to 46.2%, up from 5.5% at the end of June. In July, about 62% of trading took place outside regular U.S. stock market hours. At the industry level, on-chain transfers of tokenized stocks exceeded $100 billion in the third quarter of 2026. The product is issued by an entity associated with Abu Dhabi Global Market (ADGM) and is available to eligible users in permitted jurisdictions; it may not be available in some regions.

On October 15, Binance announced the addition of two seller strategies to its stock options product line: Covered Calls and Cash-Secured Puts. After holding the required collateral, users sell options and collect the premium upfront. A Covered Call involves holding the underlying stock and selling a corresponding call option; the premium is credited immediately. If assigned, the stock is sold at the strike price, capping potential upside at that price. A Cash-Secured Put involves selling a put option and reserving enough cash to buy the stock if assigned. The collateral is frozen $USDC; if assigned, users must buy the stock at the strike price, even if its market price is lower.

Collateral for both strategies remains frozen until the position is closed, the option expires, or assignment occurs. Only limit orders are supported, and users must use a Funding Account and complete an options suitability assessment and risk disclosure. Settlement is physical delivery of shares, which Alpaca holds on behalf of Binance users. Nest Trading Limited acts as the introducing broker and routes orders to Alpaca Securities LLC. Most U.S. stock options trade from 9:30 a.m. to 4:00 p.m. Eastern Time (some ETFs/ETNs trade until 4:15 p.m.), approximately 9:30 p.m. to 4:00 a.m. the following day in China Standard Time. These products are part of the TradFi stock options suite and may not be available in some regions.
