Odaily: Brazilian Supreme Court Justice Luiz Fux will hold a public hearing on November 3 regarding the ban on sports betting and online casinos, and has not yet ruled on whether to suspend the ban. The hearing is scheduled for 10 a.m. local time and will focus on the economic impact of the ban.

The ban took effect on October 25, and Brazil's 85 gambling licenses were invalidated as a result. Brazilian President Luiz Inácio Lula da Silva won re-election on the same day, and the gambling industry organization ANJL called for the resumption of dialogue with the government.

The hearing will have 26 participants, including relevant litigants, government agencies, football clubs, and industry organizations; individual betting operators were not invited. Congress was initially required to vote on the provisional measure by November 23, with the deadline extendable once for up to 60 days. (Bitcoin.com News)

Odaily reports: According to Bitcoin News monitoring, Electrum released version 4.8.3 on October 24, 2026, fixing a security vulnerability that has already been exploited in real attacks. Malicious servers could display fabricated transactions to users and, when users attempt to speed up transactions via Replace-by-Fee (RBF), trick them into signing transactions that pay the attacker's address; the attacker does not need to obtain the user's private keys. Electrum stated it has received two related reports, in which one user lost bitcoin after increasing the fee, and recommends that users update to version 4.8.3.

Odaily report: Trader Killa posted that he still holds a Bitcoin long position with an entry price of $76,400. His trading plan remains completely unchanged, and he will not move the stop-loss up to the entry price. Instead, he will continue holding until the target price is reached or the stop-loss is triggered. To capture major market moves, one must patiently endure prolonged consolidation ranges and tedious price fluctuations.

Killa also stated that frequently changing trading stance is precisely the reason many traders lose money. The key lies in whether the market structure and trading plan have changed; currently, neither has changed, so he will not panic or waver.

Odaily reports: Data from crypto market data firm Kaiko shows that USDC now accounts for 56% of euro stablecoin trading volume, up from 10% in January 2024, and has surpassed USDT. The shift in market share accelerated after multiple exchanges in the European Economic Area restricted USDT trading in accordance with the Markets in Crypto-Assets Regulation (MiCA).

USDC's liquidity in euro-denominated trading has also surpassed USDT, with its order book depth approximately 40% higher. However, USDT remains the larger stablecoin globally, with a circulating supply about 2.5 times that of USDC.

About two weeks ago, the European Banking Authority (EBA) designated USDC as the EU's first "significant e-money token" under the MiCA framework and placed it under direct supervision. Kaiko also noted that the U.S. GENIUS Act could drive similar trading shifts on U.S. platforms; Tether, meanwhile, has launched USAT, a stablecoin aimed at the U.S. market. (Cointelegraph)
