Does Coin have any charges?

Excuse me, I was just reading through the information on Coin and I noticed that there wasn't much mentioned about fees or charges. I was wondering, does Coin impose any kind of charges on its users? Are there any transaction fees, maintenance fees, or any other types of costs that I should be aware of? I'd like to make sure I have a clear understanding of any potential expenses before I proceed with using the platform. Thank you for your help.
