Could you elaborate on the steps required to effectively utilize the Gate.io wallet? I'm new to the world of cryptocurrency and finance, and I'm interested in understanding the process of setting up and managing a Gate.io wallet. Specifically, I'm wondering about the initial setup, depositing funds, trading options, withdrawing funds, and any security measures I should be aware of. Additionally, I'd like to know if there are any fees associated with using the wallet and whether there are any limitations or restrictions to be mindful of. Your guidance would be greatly appreciated as I embark on this journey of exploring cryptocurrencies and digital finance.
