You can use Youtube. there are a lot of ads in youtube. maybe they won't banned it there because they can make youtube videos about crypto

The best place to advertise can be Twitter and Facebook and here Bitcointalk. And if all things are forbidden, I have not figured out yet another effective way to advertise than Youtube. Right?
