How do you tell if you have too much protein?

I'm curious, in the realm of cryptocurrency and finance, how do we discern if we've overinvested in a particular asset, similar to how one might determine if they've consumed too much protein? In the crypto world, it seems like everyone is always searching for the next big token or project, but how do we know when we've allocated too much of our portfolio towards a single asset or sector? Is there a metric or rule of thumb that can help us avoid the pitfalls of overexposure, just as we would monitor our dietary protein intake?
