I am using youtube app for last 2 years . first only I saw videos in youtube.there are many types of videos you get. You can get technology, funny, frank, vines, vlogs, health beauty related videos.and you can also create videos and upload it on youtube.And also earn money from ads, sponsherships and affiliate marketing.But the bad side of youtube is some videos are fake, so some viewers cannot know about fake videos and lost their time. But I provide that if the video has 10% of like then that is a real video.also you can check the comment section before watching the video to know either it’s real or fake.i am saying this becase I am also a creator .
