If you are a professional of some sort, you can share your experience with other people to generate revenue. Here are some Investment plans for making an online teaching platform.
Making YouTube Channel
YouTube is a free video streaming platform, where you can post videos and make money. If you are some sort of professional and can teach it well, making YouTube videos is going to be a good investment. The more people watch your videos, the more revenue you earn from them.
This is the most common way to announce your content to the world. If you have made videos about the skill that you want to share, you can make a website for other people to have access to them. Also, the prepaid option can be a great way to make money. If people want to access the videos, they have to pay a certain amount of money.
Making Patreon Account
This is another website where you can upload your online tutorial, and people will pay a certain amount to watch them and learn. This is a great investment, as you only have to invest one time during the making of the videos.
