Bitcoin's Record Weekly Surge and Crypto Security Fixes

Bitcoin's price surged over 20% in the past week, marking its strongest weekly gain in three years, with the cryptocurrency trading above $77,000 on Monday morning. This rally also drove record capital inflows into both Bitcoin and Ethereum exchange-traded funds. Ethereum rose approximately 31% to above $2,450, while the crypto Fear and Greed Index jumped to 73 points, indicating investor "greed" after starting the previous week at just 31. Bitcoin ETFs saw inflows exceeding $1.9 billion, and Ethereum funds attracted nearly $700 million, both reaching their highest weekly levels since last autumn. Analysts attribute the growth to rising US government debt and liquidity shifts into scarce assets, with some predicting a powerful Bitcoin cycle. Security researchers found and fixed vulnerabilities in Ledger's Ethereum app and the Sandbox NFT project's cross-chain bridge, with the latter's impact affecting less than 0.01% of token supply.
