Ive seen many people become successful and famous off of youtube and I was wondering your opinions on it?

 

If its for gaming, imo you will not be successful, at least as far as making a living off of it goes.
If anything else, depends on the content and what you can provide that others cannot, something that makes you you and is engaging enough to draw users back repeatedly.
Really you could be successful with a gaming channel, but the chances are insanely lowered given the incredible saturation for it currently.
