Stanford University researchers have published a study suggesting that some traders in Polymarket's main BTC prediction market may have temporarily moved BTC prices to influence betting outcomes. According to Bloomberg, the researchers identified a pattern on Binance where concentrated, one-directional trades in the final seconds before a bet expired caused temporary price fluctuations, benefiting traders who had bet on that direction. This phenomenon was most pronounced when a slight price change could determine the outcome of a bet. The researchers concluded that this was an attempt to manipulate results by temporarily pushing the spot price. They noted that while Polymarket's five-minute BTC price bets are settled based on data from multiple oracles, approximately 85% of contract outcomes during the study period moved in the same direction as Binance's price, implying it was used as a proxy for the final settlement price. Although the traders' intent was not directly observed, the researchers inferred the possibility of price manipulation by analyzing trading patterns. The study pointed out that unlike prediction markets for elections or sports, those based on financial assets carry a structural risk of manipulation because participants can directly trade the underlying asset that determines the outcome.

CoinMarketCap's Altcoin Season Index has fallen seven points from the previous day to a reading of 45. The index measures whether 75% of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped tokens, have outperformed Bitcoin over the past 90 days. A score closer to 100 indicates an "altcoin season," while a lower score suggests a "Bitcoin season."

Bitwise has revealed that while cryptocurrency prices fell by approximately 36% in the first half of 2026, crypto-related stocks saw a 23% increase. This performance was the second-highest return among all major asset classes, trailing only emerging market stocks. Ryan Rasmussen, Head of Research at Bitwise, explained that the 30 publicly traded companies in the Bitwise Crypto Innovators 30 Index delivered returns twice as high as the broader U.S. stock market. He attributed this to several key factors, including mining companies benefiting from the growing demand for AI computing, as well as the growth of stablecoin issuers and asset tokenization platforms.

Solana (SOL) has historically been a superior diversification asset compared to Ethereum (ETH), according to Morgan Stanley investment strategist Denny Galindo. In an interview with CoinDesk, Galindo noted that with the launch of spot ETFs, many investors are considering which digital assets to hold alongside Bitcoin, and he believes SOL has historically provided better diversification effects than ETH. Galindo explained that through April 2026, the correlation coefficient between Bitcoin and ETH was 0.78, while the correlation between Bitcoin and SOL was lower at 0.72. This indicates that SOL was slightly less likely to move in the same direction as Bitcoin. He added that when SOL moves in a different direction from Bitcoin, its correlation with traditional assets like stocks also tends to be lower than that of ETH. Based on these historical correlations, Galindo concluded that SOL can be a better diversification asset than ETH.

The proprietary Fear & Greed Index from cryptocurrency data provider CoinMarketCap registered 35, up one point from the previous day, keeping the market in a state of "Fear."

Prominent Bitcoin critic and Euro Pacific Capital CEO Peter Schiff predicted on his YouTube channel that the market will collapse even without any significant selling from corporate Bitcoin holder Strategy. He forecast that Bitcoin could fall to a low of $20,000. Schiff argued that Strategy founder Michael Saylor knows the price would plummet if the company began to sell its holdings in earnest. Because the market is aware of this predicament, he believes it will collapse regardless of Strategy's actions. He identified key technical resistance at $65,000 and support around $58,000, suggesting that a break below this support level would send Bitcoin under $50,000 and toward a low of between $20,000 and $30,000. Schiff also added that while he does not regret failing to buy Bitcoin five years ago, it is natural to think he should have purchased it 15 years ago.

According to on-chain analytics firm Glassnode, the recent rebound in Bitcoin has been met with an increase in both stop-loss selling from long-term holders and profit-taking from short-term holders. The firm noted that in addition to selling pressure from long-term holders trying to cut their losses, short-term holders who bought near the recent bottom are now engaging in their largest scale of profit-taking since May. Glassnode concluded that on-chain data shows Bitcoin is currently under pressure from both of these selling forces simultaneously.

More than 95% of the code at Coinbase is now written by or with the assistance of Large Language Models (LLMs), according to Rob Witoff, the U.S. crypto exchange's head of platform. In an interview with Cointelegraph, Witoff said this figure is more than double the 40% estimate the company provided in February. He explained that while core cryptographic code is still developed by the industry's top cryptographers, AI is actively used to verify that the code functions correctly, is free of vulnerabilities, and performs accurate computations. Witoff added that this has allowed tasks that previously required more than 10 people to be handled by just two or three employees.

The success of Robinhood's Ethereum Layer 2, Robinhood Chain, could serve as a significant milestone for the institutional use of Ethereum, Cointelegraph reported. In this regard, Alex Gluchowski, CEO of the developer behind ZKsync, another Ethereum Layer 2, said that Robinhood's launch shows Ethereum has evolved into an infrastructure that regulated, publicly traded companies can use for their business operations. Max Shannon, a senior researcher at Bitwise, commented that the success of Robinhood Chain is far more meaningful than that of other Layer 2s. He noted that it validates the growth of the Ethereum ecosystem among major institutions and could create synergy by aligning with the Ethereum Foundation's strategy for institutional scaling. However, Shannon added that no one has yet found an answer to whether Layer 2 activation ultimately leads to an increase in ETH's value. He suggested that Robinhood will not solve this issue either, and that a fundamental change is needed in developers' approaches and Ethereum's token economy itself.

Jesse Pollak, the developer leading apps for Coinbase's Layer 1 network Base, has stepped down after admitting his on-chain social strategy failed, CoinDesk reported. For the past two years, Pollak had championed the idea that builders and on-chain social experiences would drive the next wave of growth in cryptocurrency. In a post on X, he stated that social applications have completely collapsed and admitted he was wrong. Pollak added that Base's focus on social features caused it to lag behind competitors in key areas such as trading, tokenization, and payments. He said he has handed control of Base apps back to Coinbase headquarters. Crypto trader Jordan Fish, better known by the pseudonym Cobie, is set to take over as head of development.
