According to data from TheMinerMag, in the first quarter of 2026, publicly listed Bitcoin mining companies including MARA, CleanSpark, Riot, Cango, Core Scientific, and Bitdeer collectively sold over 32,000 BTC, surpassing the total amount sold throughout last year and even exceeding the sell-off levels triggered by the Terra-Luna collapse in Q2 2022, setting a "new record for a single quarter."The backdrop of this sell-off is the key metric for measuring miner profitability, "hashprice," which has fallen to a historical low of below $35 per PH/s per day, with about 20% of miners already in the red. Asset management firm CoinShares stated in its report: "Unless the BTC price rebounds significantly, high-cost miners will further capitulate in the first half of 2026."

The U.S. Court of Appeals for the Ninth Circuit heard oral arguments from lawyers representing the prediction market platform Kalshi and Nevada authorities regarding Nevada's ban on the platform's event contracts. This appeal stems from a lower court ruling that prohibited Kalshi from offering certain event-based contracts in Nevada based on the claim that Kalshi requires a license.The appellate court judges responsible for Thursday's oral arguments and Kalshi's lawyers acknowledged that there have been several state-level enforcement actions against Kalshi and other prediction market platforms, including criminal charges filed in Arizona. However, a federal court last week blocked Arizona authorities from enforcing the state's gambling laws against Kalshi's event contracts."I believe existing case law does indicate that what we want to avoid here is state courts and federal courts simultaneously considering the exact same issue and potentially reaching different conclusions," said Colleen Sinzdak, representing Kalshi.The core argument of Kalshi's debate is that the platform's event contracts fall under "swap" transactions and should be regulated by the Commodity Futures Trading Commission, rather than state gambling regulators. CFTC Chairman Michael Selig supported this position in the case involving Crypto.com's prediction market and Nevada authorities.Coinbase Chief Legal Officer Paul Grewal predicted that this case may be appealed to the U.S. Supreme Court. "The questions in the oral arguments are not a reliable signal of the court's leanings; nonetheless, I stand by my long-standing prediction that the Supreme Court will rule on whether sports contracts on designated contract markets fall under the exclusive jurisdiction of the CFTC as swap transactions."

According to Tech in Asia, South Korean internet giant Naver plans to promote the IPO of its fintech subsidiary Naver Financial within five years after completing a share swap with Dunamu, the operator of the cryptocurrency exchange Upbit in which it holds shares. The transaction has been delayed due to an extended antitrust review period, and the specific timetable and structure will depend on market conditions and the regulatory environment. The proposed "Digital Asset Basic Law" in South Korea may change the transaction structure or timetable.On the same day the share swap contract was signed, both parties entered into a shareholder agreement, requiring the establishment of an IPO committee for Naver Financial within one year after the share swap is completed. If the IPO is not achieved within five years, the timeframe can be extended by another two years. Regulators are also discussing a proposal to limit the shareholding ratio of the major shareholders of the exchange to within 20%, which may lead to adjustments in the transaction terms.

According to Cointelegraph, the Cato Institute, a U.S. think tank, released a report stating that the U.S. government should eliminate the capital gains tax on Bitcoin and other cryptocurrencies to make it easier for cryptocurrencies to be used as everyday currency and to promote fair competition among different currencies.Currently, U.S. tax law treats Bitcoin as a capital asset, triggering a taxable event when users pay for goods or services with Bitcoin, requiring the calculation and reporting of capital gains. This results in even small everyday purchases potentially generating hundreds of pages of tax documents, significantly increasing the compliance burden. Cato aims to remove the current U.S. tax policy barriers to the use of cryptocurrencies as currency. Cato researcher Anthony emphasized, "Congress should simplify the tax code so that ordinary Americans can easily fulfill their obligations, which will greatly alleviate the pressure of tax season and create a more competitive economic environment."According to a 2025 survey, 39% of U.S. cryptocurrency holders have used crypto assets to purchase goods and services, and currently, about 11,000 merchants worldwide accept Bitcoin payments.

According to official news, BitMEX Research has released a new research article proposing that in response to the risk of future quantum computers potentially breaking elliptic curve signatures, the Bitcoin network could adopt an alternative soft fork mechanism to "directly freeze" to reduce controversy and increase flexibility.The proposal revolves around "quantum-vulnerable fund freezing," but suggests avoiding the direct freezing of all related assets without evidence, instead gradually implementing security strategies through a verifiable condition-triggering mechanism. The core of the proposal is to establish a "signal vault," which contains special addresses generated using "accidental numbers" to prove that no one possesses their private keys. If passive spending occurs from that address, it will be regarded as on-chain evidence that quantum computing capabilities genuinely exist, thereby immediately triggering a comprehensive freeze of quantum-vulnerable assets.At the same time, the fund could attract capital through a multi-signature structure as a "quantum bounty," aimed at incentivizing potential attackers to expose their capabilities. The article also mentions that there is currently a BIP-361 proposal promoting the phased disabling of the old signature system and ultimately freezing risky assets, but this proposal is controversial due to its involvement in "mandatory freezing."The newly proposed "signal-trigger + security window" mechanism aims to replace the fixed-time freeze path, reducing potential system shocks while retaining Bitcoin's censorship-resistant characteristics, but it also brings complexity and execution risk trade-off issues.
