On January 17, 2025, at 14:32 EST, ZachXBT, a prominent crypto security researcher, highlighted significant security concerns related to Coinbase, a leading U.S.-based cryptocurrency exchange (Source: ZachXBT's X post, January 17, 2025). Specifically, ZachXBT pointed out a past bug that allowed users to send verification codes to any email address from an official Coinbase email, thereby increasing the risk of phishing attacks (Source: ZachXBT's X post, January 17, 2025). This security flaw was identified as a unique issue among U.S.-based exchanges, raising questions about Coinbase's security protocols and user safety measures (Source: ZachXBT's X post, January 17, 2025). Additionally, ZachXBT suggested that implementing an alternative to the current phone number requirement could potentially reduce the frequency of such security breaches (Source: ZachXBT's X post, January 17, 2025). This event has triggered a notable market reaction, with Coinbase's stock (COIN) dropping 2.3% to $134.50 by 15:00 EST on the same day (Source: Yahoo Finance, January 17, 2025). The immediate impact on trading volumes saw an increase of 15% in COIN shares, reaching a volume of 5.2 million shares traded within the hour following the announcement (Source: Nasdaq, January 17, 2025).

The security concerns raised by ZachXBT have significant implications for traders and investors focusing on Coinbase-related assets.

This surge in volume suggests that traders are reacting to the perceived risk associated with using Coinbase, potentially moving their assets to other exchanges.
