YouTube mobile application is a very great tool for the learners, to watch entertainment videos and to learn about many beautiful things that we do not know. I use YouTube mobile application mostly to learn new things and I watch funny videos and magic videos. Its really a cool place to make some money either. Little tricky but if you learn to make money and spend some time to create your video and post it on YouTube you can make good money. Thank to Google for YouTube videos and for its earning option.
