Scammers are everywhere and that is sad to say, schemes, fraud and fakes videos are also scattered in YouTube channel, so be careful in what to believe into.
When I was student also I used to search cooking video in YouTube especially baking, then I figure out that some video are made just for fun, some are real and most of them are fabricated.
When it come to business venture or related activities like bitcoin, or any bitcoin programs you have to check their background, vision, who are the persons involved, any achievement? History background in order to be sure, before joining them....
wise investors will not immediately believe in a video show in my opinion they will certainly check the information you mentioned above, all backgrounds and information related to a produl altcoin they will understand to further join as an investor
