【Incident】After Binance suffered the largest hack in its history last week, losing $630 million, the market continues to absorb the shock. According to Bitcoinist, BTC edged down 0.4% over the past 24 hours to around $77,900, while Binance saw net outflows of $3.64 billion in the first 9.5 hours after withdrawals resumed. Meanwhile, U.S. spot Bitcoin ETFs recorded $643 million in net outflows last Friday, the largest single-day outflow since June 25 (according to The Block). Today’s market data shows BTC down 2.25%, with a trading volume of 1.085 billion USDT, narrowly holding the $77,000 support level.
【Why It Matters】This hack is significant not only for its record-breaking scale, but also because it directly tests market confidence. Binance swiftly replenished 95% of the assets that had flowed out after the incident and completed its latest proof of reserves, allowing users to independently verify 1:1 backing for assets such as BTC, ETH, and BNB (according to The Block). This has eased some of the pressure from potential bank-run withdrawals. However, the scale of outflows remains significant: net outflows of $3.64 billion indicate that some users chose to move their assets, while $643 million in ETF outflows suggest institutional investors are also seeking safety. These fund movements are directly tied to whether BTC can hold its current key demand zone.
【Impact and Risks】In the short term, BTC is forming a key battle zone around $77,000. According to Cryptopotato, if this support level gives way, the uptrend structure in place since September could be damaged, with prices potentially testing lower levels. The risks are twofold: First, the hackers are still moving the stolen assets, which could create localized selling pressure. Second, the Fear and Greed Index has fallen to 30, putting market sentiment in fear territory (according to Cryptopotato), which often signals increased short-term volatility. However, BitMine Chairman Tom Lee believes that Ethereum’s decline of only about 4% after the hack is itself a bullish signal, reflecting a relatively restrained market reaction (according to Cryptoslate) and suggesting that resilience remains.
【Event】The ripple effects of the hack are spreading beyond Binance. According to CoinDesk, Brazilian exchange Mercado Bitcoin was attacked, and wallets on at least 10 chains were drained, resulting in losses of around $40 million. The exchange has suspended deposits and withdrawals. Meanwhile, according to Cointelegraph, South Korean regulators have urged local exchanges to strengthen cold-wallet storage, even though the country had already required exchanges to keep at least 80% of customers’ crypto assets in cold wallets.
【Why It Matters】This incident marks the spread of hacking attacks from individual exchanges across the broader ecosystem, with attackers potentially using more targeted methods. South Korean regulators’ swift intervention highlights how security vulnerabilities have become a systemic risk, potentially prompting stricter global standards for exchange asset storage. For investors, exchange security resilience has become an important factor in assessing risk, and could influence how funds are allocated between CEXs and self-custody.
【Impact and Risks】Although Mercado Bitcoin’s losses were relatively small, the attack came just days after the Binance incident and could intensify broader concerns about exchange security, accelerating outflows. If South Korea’s regulatory call leads to stricter rules, operating costs for exchanges will rise, although this could help standardize the industry over the long term. In the short term, investors should be alert to selling pressure from the hackers’ continued movement of assets, while monitoring how regulatory changes affect market sentiment. During periods of frequent security incidents, consider prioritizing diversification into self-custody wallets or cold storage.
