Bitcoin Blasts Past $85K as ETH Surges 5.6% on Massive Short Squeeze | ethereum.miami

Bitcoin crossed $85,000 for the first time since January, dragging crypto markets higher on a wave of forced short liquidations and renewed macro optimism. ETH climbed 5.66% to $2,716.17, pushing its market cap to $331.6 billion on $19.4 billion in 24-hour volume. The rally came as Brent crude fell for a fourth straight session and traders positioned ahead of a Trump-Xi summit expected later this week.

$750 Million Liquidation Cascade

CoinGlass recorded at least $750 million in crypto liquidations over 24 hours, with the overwhelming majority hitting short positions. At one point, $300 million in shorts were wiped out in a single hour. CoinDesk tracked $648 million in bearish bets specifically forced closed during the squeeze.

Open interest climbed 7.59% to $156 billion even as positions were unwound, a signal that new money is entering rather than exiting. Traders are chasing the move. Bitcoin reclaimed its 50-week moving average for the first time in 45 weeks, a technical threshold that has historically preceded sustained bull runs. Analysts caution that a single weekly close above this level does not constitute confirmation.

Monero's XMR posted the biggest gain among majors, up 13%. NEAR jumped 23% on Zcash swap traffic. The broad-based rally coincided with rising equity futures and cooling energy prices, a macro cocktail that tends to favor risk assets.

Kalshi Hit with Volume Manipulation Claims

Kalshi, the CFTC-regulated prediction and derivatives platform, is facing public allegations of inflated trading volume in its ether perpetual futures market. A trader flagged patterns of identical $5,500 trades on X, suggesting wash trading or coordinated activity designed to make the product look more liquid than it is.

Kalshi has not publicly responded to the claims. The allegation is particularly pointed given the company's ongoing effort to position itself as a credible, regulated alternative to offshore derivatives venues. Fake volume, if confirmed, would undermine that narrative directly.

Hana Bank Issues $100M Digital Bond via Euroclear

Hana Bank, South Korea's second-largest lender, issued the country's first digital bond using Euroclear's blockchain infrastructure. The five-year, $100 million foreign-currency bond settled same-day, compressing a process that traditionally takes three to five business days.

The issuance is a concrete example of blockchain reducing settlement friction in traditional finance, not as a theoretical exercise but in production with a major bank and a cornerstone piece of global market plumbing. Separately, the Bank of Korea launched a pilot enabling 24-hour won settlement for foreign investors, extending access beyond Korean business hours.

Arbitrum 70x Call, ZetaChain Migration

Standard Chartered projected that Arbitrum's token could increase 70 times by 2030, a bold call tied to the L2's position in Ethereum's scaling roadmap. The projection landed in the same news cycle as the CLARITY Act's failure to advance, leaving the regulatory picture for tokens largely unresolved despite the legalization of tokenized stocks.

ZetaChain holders voted to wind down the project's Cosmos-based Layer 1 and migrate ZETA to Solana. The move follows a pattern of smaller chains abandoning standalone infrastructure in favor of more established networks. For Ethereum-aligned builders, it is a reminder that L2s offer a way to stay connected to the largest smart contract economy without bearing the overhead of an independent chain.

North Korean Hackers Infect 30,000 Devices

North Korean cyber group WaterPlum infected at least 30,000 devices across more than 100 countries using fake job offers at crypto, AI, and NFT companies, stealing $10.7 million in cryptocurrency. The operation targeted developers specifically, exploiting the remote-first hiring culture prevalent in web3.

France, meanwhile, logged its 70th physical "wrench attack" in the first eight months of 2026, making it the worst-hit country for in-person crypto extortion. The latest incident involved the children of a crypto worker held hostage, with $46,000 taken. Hardware wallet providers like Ledger, headquartered in Paris, have repeatedly warned about operational security practices, but the attacks keep escalating.

X Takes Its Own Users to Court Over Crypto Bot Fraud

X filed lawsuits against operators of fake Bitcoin news accounts that allegedly coordinated posts and engagement to fraudulently extract creator revenue-sharing payouts. The platform alleges two UK-based users, Vivek Kumar Sen and Zmyang Sherpa, ran bot farms that generated at least $277,000 in payouts, with total claimed and projected losses reaching $378,000.

The suits are unusual in that X is suing its own users rather than external bad actors. The scheme exploited the creator monetization program Elon Musk introduced in 2023, using crypto content as bait for algorithmic engagement.

Miami Scene: Squeeze Rally Puts Local Builders on Alert

Miami's crypto corridor is watching this rally with particular interest. The city's concentration of trading desks, from Blockchain.com's downtown offices to the cluster of OTC firms in Brickell, means a $750 million liquidation event generates real local activity. Several Miami-based proprietary trading groups run strategies specifically designed to capitalize on short squeeze cascades, and today's price action likely tested those systems at scale.

For the city's growing RWA sector, the Hana Bank digital bond issuance is a proof point with direct relevance. Homebase, the Miami-based real estate tokenization platform, has been building on the premise that blockchain settlement can compress timelines and reduce costs in property transactions, precisely the dynamic Euroclear demonstrated with Hana's bond. Same-day settlement of a $100 million instrument validates the thesis that tokenized assets can outperform legacy rails, a message Homebase and Securitize have been pitching to South Florida's real estate market for years.

The next major gathering on the local calendar is Miami Blockchain Week, now roughly six weeks out. If Bitcoin holds above its 50-week moving average through the end of September, expect the mood at that event to shift considerably from the cautious tone that dominated earlier this year.
