Just done everything asked in the vid, whats the purpose behind this if i may ask?
nice idea, is this your first attempt at this?
Seems to me one of your friends is going to win this 'giveaway'. Makes no sense you giving $100 for people to do a survey where you make money and then subscribe to your YouTube to promote your music. If there was ever a clearly fake giveaway it would be this one.
People don't just hand out $100 to people on the internet.
It's just a way for him to promote his own music and like Tomix said, one of his "friends" will probably "win". It's just a click bait technique.
