Making a passive income and investing are the two best ways to make money and steemit provides users those opportunities. This platform provides you to do what you like and build your worth at the same time. With other passive incomes you would usually have to make an investment then the income comes in but you do not have to do that with steemit. For a person to make passive income from writing a book you have to invest in the tools to write it. Steemit provides the tools for you and you dont have to pay for it. Steemit actually give you money once you sign up. People get paid for creating content and once that content is on the blockchain/internet you continue to get paid off of it depending on how much people upvote it. Once you get that money from your upvotes you get paid in stem dollars and you can convert that to stem power or stem; which are two investments that will continue to go up as long as people continue using this platform. Who wouldn't want to invest or get paid to do that?
