I'll add that while I totally agree that BTC isn't a hedge, it is uncorrelated with stocks and bonds. Now in a crisis when equities are getting killed then BTC will go down too (hence not a hedge).
In fairness to bitcoin though, this is true of a lot of stuff. Other stocks, corporate bonds, high yield bonds, all commodities except gold, all currencies except USD, Yen get smacked in a real crisis.
BTC is uncorrelated to stocks tho. Adding an uncorrelated asset (that has >150% annualized returns) to a portfolio is like quant magic.
Attached is rolling 52-week correlation between BTC and SPX. Notice this oscillates around 0 aka not correlated. MAYBE you can argue that it has a very small positive correlation, but its very small
Point is - while not a hedge still super useful from a portfolio standpoint
