Could you please provide a step-by-step guide on how to withdraw money from Poloniex? I'm particularly interested in knowing the process for withdrawing funds to a bank account or a cryptocurrency wallet. Are there any fees associated with withdrawing funds, and if so, how much are they? Also, is there a minimum withdrawal amount that I need to adhere to? Lastly, how long does the withdrawal process typically take, and is there anything I should keep in mind to ensure a smooth transaction?
