How to cash out Nexo tokens?

I'm curious to know the steps involved in cashing out Nexo tokens. Could you elaborate on the process for someone who may be new to the cryptocurrency world? I'm interested in understanding the best practices for safely converting my Nexo holdings into fiat currency, such as USD or EUR. Are there any recommended exchanges or platforms that facilitate this process efficiently? Additionally, I'd like to know if there are any fees or tax implications associated with cashing out Nexo tokens. Your insights would be greatly appreciated.
