An "inflation hedge" goes up when inflation is up, and down when inflation is down. But in practice, BTC is closer to down when inflation is up, and up when inflation is down.
It isn't a perfect inflation hedge, no one is claiming that. You are cherry picking a single interval where the correlation is negative. If you zoom out, you'll find that the correlation is mostly positive. Past correlation is also not predictive of future results.
