According to SoSoValue data, due to the shortened trading week caused by the President's Day holiday, US Bitcoin spot ETFs saw a net outflow of approximately $316 million last week, marking the fifth consecutive week of net outflows and the longest losing streak since early 2025. Ethereum spot ETFs also showed a weakening trend, with a net outflow of approximately $123 million last week. In contrast, altcoin spot ETFs demonstrated stronger resilience. The Solana (SOL) spot ETF recorded a net inflow of approximately $14.3 million last week, and the XRP spot ETF also recorded a small inflow of $1.8 million. Furthermore, Bitcoin prices fluctuated due to the policies of US President Trump. Trump announced a proposed increase in tariffs on global imports from 10% to 15%, and invoked Section 122 of the Trade Reform Act of 1974 to bypass the Supreme Court's previous ruling on the overreach of the International Emergency Economic Powers Act (IEEPA). Market analysts believe that the inflationary risks and global economic growth uncertainties triggered by the tariff policy are putting pressure on risky assets such as cryptocurrencies.
