It is important to have a variety of uncorrelated assets, but in the case of Bitcoin it's still quite volatile, not always for clearly apparent reasons. It seems to be developing a place for itself, but I think it still needs a few years of less volatility for it carve out the niche many people want it to have.

And yet Bitcoin plummeted in value at the same time as everything else at the start of the pandemic, so it's hardly uncorrelated.

Buying lottery tickets would be uncorrelated. And you've less chance of being scammed or hacked when you do that...

A lot of things were correlated then that aren’t always / normally. Bonds, stocks, gold... basically everything was sold to move into dollars. That doesn’t mean that those assets are all correlated over the long haul.
