How to sell OMG Network?

I'm interested in learning how to sell OMG Network tokens. Could you please walk me through the process step-by-step? I'm not very familiar with cryptocurrency exchanges, so I'd appreciate it if you could explain the process in simple terms. Also, are there any specific exchanges that you would recommend for selling OMG Network? Are there any fees or taxes that I should be aware of when selling my tokens? Lastly, is there a best time to sell OMG Network, or is it more of a personal decision based on my financial goals?
