Everyone I think know about youtube. This is a way to share your knowledge to other and have a very big platform to earn money. Through upload video and in video adds come and by this way so many are big earning . the earning depends upon the country .for ex if you are uploading video on youtube and a person from india and a person from austrailia watch this vide and the both the people watch the adds then the people of austrailia watch the add was more profit to youtube owner by this way it depends upon country. It is also a big platform to know anything about. And you can also study from youtube . entertain yourself from youtube andso on. The loading video is very fast so that I like this thanks
