The US BTC spot ETF has seen net inflows for six consecutive weeks, totaling $3.4 billion. Among them, BlackRock's IBIT and Fidelity's FBTC contributed 80% of the funds. But here's the interesting part: BTC's price surged to around $80K and started consolidating, giving room for mainstream/altcoins to catch up. Historically speaking, continuous ETF fund inflows often signal the prelude to a market rally. Back in January 2024, after the ETF launch, BTC took three months to climb from $40K to $70K. Will history repeat itself this time? The answer is uncertain, but $3.4 billion in real money definitely doesn’t lie.
