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.
