Bitcoin spot ETFs are showing impressive momentum so far this year—cumulative inflows have hit 3.8K BTC, already outpacing last year's 3.5K BTC for the same timeframe. What's interesting here is the seasonal pattern. January tends to see relatively modest inflows, but the real action kicks in when February rolls around. From February through April, that's when major capital typically flows in. Understanding these cycles can help traders anticipate market moves and positioning.
