The week's focus centered on decisions from three major central banks: the U.S. Federal Reserve (Fed), Bank of England, and Bank of Japan. On September 17, the Fed implemented an expected 25 basis point interest rate reduction, supporting price growth for Bitcoin and Ethereum - the leading cryptocurrencies gained 4% and 8% respectively. This decision signals monetary policy easing, which traditionally stimulates risk assets including cryptocurrencies. The Banks of England and Japan also published their policies and commentaries affecting global financial market currency and liquidity flows.
Market Dynamics and Major Purchases
The week featured cryptocurrency market volatility, yet institutional players confirmed their interest through significant acquisitions. For example, Galaxy Digital purchased 1.2 million Solana tokens worth $306 million, highlighting focus on promising infrastructure projects. Furthermore, a major player's strategy included adding 850 Bitcoin worth approximately $100 million, demonstrating faith in long-term market growth.
Technical Events and Hacking Incidents
Concerning news included the Layer 2 Shibarium network breach, associated with Shiba Inu token, resulting in approximately $2.4 million stolen, causing noticeable price declines for meme tokens SHIB and Dogecoin. Additionally, Monero experienced its largest-ever blockchain reorganization (reorg) with 118 transactions reversed, representing a significant technical event for network protection and operational stability.
Regulation and Legislation
Meaningful regulatory steps were undertaken at international and national levels. The U.S. Senate is considering advanced cryptocurrency market structure legislation aiming to clearly define SEC and CFTC roles and protect users from fraud and speculative abuses. Simultaneously, the U.S. Treasury Department initiated formal rulemaking for stablecoins, expanding the GENIUS Act framework to strengthen combating illegal activities in the crypto sector and enhance transparency. European countries including France, Austria, and Italy advocated for strengthened crypto market oversight at EU level, including stricter supervision of platforms from outside the union under MiCA. U.S. regulators SEC and CFTC announced a coordinated approach to creating comprehensive digital asset regulatory framework aimed at supporting innovation and investment while ensuring market participant protection.
Technological and Industry Developments

Meanwhile, popular Layer 2 solutions like Arbitrum maintain community attention due to ongoing token unlocks and updates. Base protocol, widely known as Ethereum Layer 2 solution, is considering issuing its native token, potentially expanding its ecosystem and functionality. At conferences including Blockchain Expert Conference 2025 (Tel Aviv), EDCON (Osaka), and other global forums, key blockchain development, security, regulation, and Web3 issues were discussed, gathering leading experts, investors, and regulators.

Cryptocurrency mining company stocks demonstrated mixed performance: AI-technology mining companies like Bitfarms, IREN and Hive showed significant growth, while KindlyMD (NAKA) fell 55% after registering new shares for PIPE investors, enabling insider selling.
Thus, the week of September 15-21, 2025, represented an important phase demonstrating the combination of macroeconomic policy, institutional interest, regulatory efforts, and technological innovations. For crypto industry newcomers, this period emphasizes how strongly the market depends on both global financial sentiment and political decisions, as well as technical security and regulatory clarity.
