Youtube is the best platform for the world.I can give a 5/5 review for this.
Youtube is not only a seller but also buyer.This attracts people on to the platform created so that they can make a channel and attract people through videos, views etc.
It creates oppurtunity to the youngsters to earn and learn too.
I strongly believe Youtube helps people in lots of ways and donot have any cons yet.
It creates oppurtunities to businessess and the customers too.
Google adsense and adwords from this website created a great deal for people all over the world ofcourse except china.
