There are some people in youtube, they show their faces upon reviewing, you can't just be sure if they can really influence people to invest in your project. And they are risking their names as well so you better prepare a good pitch for it.
What you can do is contact the people who do own facebook groups which is related to crypto, they are likely to respond than those who risks their names and faces. If you turned out to be scam, its their only facebook group that will be ruin. Worth a try probably. I wonder how much you'd pay.
thanks
about crypto groups in facebook: the majority of them does not seem very popular and relevant
maybe you can send some links to such groups?
There are huge crypto related groups in facebook scammers are even cramming those pages because they knew they can attract users to send without suspecting them. You can check each groups with about 50K to 100K members, the admin of those groups are reminding everyone what to do scams. I don't see them as marketer but I think you can contact them and promote on their groups without getting banned by the admin. I'm sure those members somehow believe to the admin of the group.
