Can I Unstake my Ethereum now?

Could you please clarify for me, is it possible to unstake my Ethereum at this moment? I'm somewhat confused about the current market conditions and if it's advisable to do so. Given the volatile nature of cryptocurrencies, I'm worried about potential losses. Could you also provide some insight into any potential fees or penalties involved in the unstaking process? Would it be beneficial to wait for a more favorable time, or is there no significant risk in doing it now? Thank you for your guidance.
