How can I withdraw my money from crypto?

Could you please explain to me how I can withdraw my funds from cryptocurrency? I've been investing in crypto for some time now and I'm ready to cash out my profits. Could you guide me through the process step by step? I'm particularly interested in understanding the withdrawal options available to me, any associated fees, and the estimated time it would take for the funds to reach my bank account. Additionally, are there any security measures I should take to ensure a safe and smooth withdrawal process? I'd appreciate it if you could provide detailed answers to these questions. Thank you in advance for your assistance.
