What happens if you Unstake?

What happens if you Unstake? Could you elaborate on the consequences of this action? I'm curious to understand the potential impacts it might have on my cryptocurrency holdings. Would Unstaking result in any penalties or fees? How would it affect my staking rewards? Would my funds become immediately available for withdrawal, or would there be a delay? It would be helpful to know the general process and any specific steps I need to take when Unstaking. Could you also provide any advice on when it might be a good time to Unstake, based on market conditions or other factors?
