Bitcointalk is suited for education, YouTube just for hype and YouTubers are milking hype.
YouTube can still have the positive side for Bitcoin educational contents. The advantage Bitcointalk has over YouTube is that the community was made for Bitcoin lovers first before considering other users who will like to promote FUD, propaganda and hate. If we truly feel concerned about the growth of Bitcoin in the near future then we should not just limit our interaction about bitcoin only on the forum. We too can create contents about bitcoin and limit the hype and FUD. We all collectively make up the community and it is our selfless contribution beyond the forum will help reduce the hype.
