The Team has released several videos of Team Members and their Advisors previously, but there is no specific bonus for youtube, at least I did not see it. The answer to this question will be best answered in telegran Ehealth
As far as i know they don't have a bounty program for youtube, content etc.
They just had something for telegram but probably over.
It would probably be smart for them to revive their bounty campaign before their ICO so at least community members would promote their project if their members are not doing such a good job.
So Chris will also have to organize a bounty campaign.
