I will promote your crypto token, coin, exchange on my 19k Crypto Community channel GoUP - https://www.youtube.com/c/GoUpYoutube
You just have to tell us roughly about what the topic is to prepare as well as possible and to send maybe some materials and links. The video will last between 4-10 minutes, it all depends, you also get and thumbnail with your logo (send preferably PNG or JBG format).
