Hi,
a friend is moderator for an exchange that has just been published.
It's a centralized exchange, and it looks for tokens to add, obviously for free.
The interface is quite nice.
I don't know if I have the right to post the link here, so feel free to send me a private message.
Thank you

Just tell us what's the site, why do you need to hide it and only tell us through pm?
It's bit suspicious and i doubt it's legit exchange as they way you advertized is, its not proffessional
