I had been using YouTube for many years now. And I also had a chanel on YouTube named suraj wagle where I upload a comedy video.
It has every kinds of videos from comedy, action, knowledgeable, movies, songs and many more. People even make money from YouTube by uploading videos about anything they like just like me. The adsense paid the YouTubers for the ads they put on their channel.
Youtube is like a wormhole when you enter the whole you cannot get out. You just find new videos on recommendations to watch. And you will realise that you had lost a lot of time. ????
But all in all you will find solutions to everything in their just I like used for making some food, how to open Internet banking, how to convert word to pdf, how to solve any problems related to maths or accounting.
So it has its bad and good both sides. It wastes your time if you stuck in its wormhole and it also passes your time . It will help you to solve any of your issues or problems and earn money also as people earn thousands of dollars. Just find a right video. In all its a great app. I really like this app.
