Bull Bitcoin, a Bitcoin-exclusive exchange, announced a deep integration with Payjoin, claiming to be the world's first Bitcoin exchange to offer Payjoin as a deposit and withdrawal option, introducing two new concepts: "default Payjoin" and "Payjoin transaction." Founded in 2013 by Francis Pouliot in Canada, Bull Bitcoin is the longest-operating Bitcoin-exclusive exchange globally, with its non-custodial platform allowing users in Canada, Europe, and Latin America to buy Bitcoin directly into their wallets or sell Bitcoin to bank accounts. The company also developed the free and open-source Bitcoin self-custody wallet BULL Wallet, which has been self-funded since its inception.Payjoin is an on-chain privacy protocol for Bitcoin that breaks the fundamental assumptions made by on-chain analysis companies about user behavior, such as the assumption that one of the unspent transaction outputs (UTXO) generated by a transaction is change returned to the sender. The protocol adds a layer of off-chain coordination that obscures user intent by making the amounts sent and returned ambiguous, thus protecting on-chain privacy without requiring a hard or soft fork of the Bitcoin consensus. When BULL Wallet users buy and sell Bitcoin on-chain through the built-in exchange, transactions will default to using Payjoin, helping buyers passively aggregate UTXOs in their wallets, reducing future Bitcoin miner fees while shrinking the Bitcoin UTXO set size and alleviating fee pressure for all users.Payjoin transactions are used to protect users from malicious actors attempting to glean their financial habits through on-chain analysis. Since Bitcoin transaction amounts are public, outsiders may infer personal salaries or investment strategies, and as a non-custodial exchange, Bull Bitcoin leaves an on-chain trace for every transaction. In December 2024, BULL Wallet became the world's first wallet to integrate the Payjoin V2 protocol, a project advanced in collaboration with Dan Gould and the Payjoin Dev Kit team, with all related wallet and exchange software being completely free and open-source. Users only need to download BULL Wallet, create a Bull Bitcoin exchange account, and log in through the BULL mobile app, with the rest of the process being automated.

According to Coinglass data, if Bitcoin falls below $75,000, the cumulative long liquidation intensity on mainstream CEX will reach $550 million. Conversely, if Bitcoin rises and breaks through $80,000, the cumulative short liquidation intensity on mainstream CEX will reach $1.45 billion.The liquidation chart does not show the exact number of contracts pending liquidation or the exact value of contracts being liquidated. The bars on the liquidation chart represent the significance of each liquidation cluster relative to nearby liquidation clusters, that is, the intensity. Therefore, the liquidation chart shows to what extent the underlying price reaching a certain position will be affected. Higher liquidation bars indicate that once the price reaches that level, there will be a stronger reaction due to liquidity waves.

The Financial Action Task Force (FATF) released a new report titled "Combating the Full Chain of Illegal Fund Flows Related to Scam Hubs," calling on countries to take globally coordinated action to dismantle scam parks and their criminal networks.The report points out that criminals use channels such as cash, virtual assets, and instant payment platforms to launder money, and leverage AI, deep forgery, and automation technologies to scale up their operations. Among these, virtual assets have become the core channel for money laundering; in some cases, scam hubs even have dedicated over-the-counter trading counters for handling virtual asset exchanges and domestic fund transfers.In one case, blockchain analysis revealed that the total amount of funds sent in by victims exceeded $100 million, ultimately flowing into a cluster of virtual asset wallets associated with a particular scam hub.To address this, the FATF proposed six core principles, including focusing on a broader criminal ecosystem, end-to-end disruption of illegal fund flows, enhancing interdepartmental information sharing and cooperation, rapid cross-border action (especially within 24-72 hours after an incident), a victim-centered approach, and continuously adapting to changes in criminal methods.
