After being boosted by confidence in the US technology giant Nvidia's better-than-expected earnings report, the attitude of Wall Street capital has changed significantly, and the risk appetite in the global capital market has quickly rebounded.It not only promoted the rise of the US stock market, but also directly affected the sentiment of the Bitcoin spot ETF market on Wall Street. Therefore, after experiencing five consecutive weeks of net outflows of more than US$3.8 billion in cumulative capital from mid-January to mid-to-late February 2026, the Bitcoin spot ETF finally ushered in a strong reversal in the last week of February! Judging from specific data, Wall Street's Bitcoin spot ETF has achieved net purchases of over US$250 million in funds for three consecutive days.Among them, on February 25, the day Nvidia announced its financial report, the net inflow of Wall Street spot ETFs was exciting, reaching a net inflow of US$510 million.This inflow is the largest single-day net buying since February 2 of this month ($560 million).
