What comes back to roost?

I'm curious, can you elaborate on the phrase 'What comes back to roost'? It seems to suggest that something that was done in the past will eventually have its consequences. In the context of cryptocurrency and finance, could you give an example of how this might apply? Perhaps it refers to a poor investment decision made during a bull market that eventually catches up with an investor during a bear market? Or maybe it's related to the long-term effects of unregulated trading practices? I'd be interested to hear your thoughts on how this phrase might be relevant in our field.
