How do I convert ETN?

Excuse me, I was wondering if you could help me understand how to convert ETN? I'm new to the world of cryptocurrency and I'm trying to navigate my way through it. I've heard that ETN can be exchanged for other digital currencies or even for fiat currencies, but I'm not sure where to start. Could you walk me through the process? Are there any specific exchanges or platforms that you recommend for converting ETN? Also, are there any fees or commissions that I should be aware of? Thank you in advance for your help.
