How do I cash out on Bigtime?

As a cryptocurrency investor, I'm curious about the process of cashing out my holdings on Bigtime. Could you explain the steps involved in withdrawing funds from this platform? Specifically, I'd like to know about the conversion rates, transaction fees, withdrawal limits, and any other key considerations I should be aware of before initiating a withdrawal. Additionally, I'm interested in understanding the security measures Bigtime employs to ensure the safety of my funds during the withdrawal process. Thank you for your assistance in clarifying this process.
