How do I withdraw money from big time?

As a crypto enthusiast and someone who values financial security, I'm curious about the process of withdrawing funds from "Big Time" - a hypothetical cryptocurrency exchange platform. Could you please elaborate on the steps involved? Specifically, I'm interested in knowing if there are any prerequisites, such as minimum withdrawal limits or verification requirements. Additionally, I'd like to understand the typical timeline for the withdrawal to reflect in my bank account, and if there are any associated fees or charges that I should be aware of. Your insights would greatly assist me in navigating this process and making informed decisions regarding my cryptocurrency holdings.
