Participate in royalty-based venture financing. In traditional venture financing, an investor buys a stake in a company to provide growth capital to its founders. This investor is then entitled to a percentage of the gains experienced when a company is bought or has an initial public offering. However, there is another kind of venture financing where an investor can invest start-up capital in exchange for regular royalty payments that are based on the company's revenue. This doesn't give the investor any ownership in the company, but does guarantee regular payouts (assuming the company survives).
Passive income is the Holy Grail for online marketers. It's automatic. Effortless. But, not at first. In the beginning, it's grueling. I liken this to doing the most amount of work for the least initial return. However, over time, as your passive income begins to increase, your reliance on an active income plummets. That's when the real magic starts to happen.
There are dozens of ways to generate passive income. However, the option you select has to do with two metrics: time and money. Either you have a lot of time or a lot of money. Most people usually don't have both. But, if you have a lot of money, generating passive income almost instantly is easy. You can buy up some real estate and begin enjoying rental income. Or, you can invest in a dividend fund or some other investment vehicle that will begin generating a steady income for you.
