Yeah that is right affiliate marketing is a good way to earn profit that is no capital, the problem there is the trust you need a big community of audiences to make sales and get commissions another thing is there are so many people around that do the same thing they are your rival, so for me still it is not easy to do affiliate marketing it only sounds so easy but in reality its not.
I think there is no business that does not have capital. We cannot define capital as money alone. Capital is the same as the preparations we already have to start a business. I agree with what you said. Affiliate business is not as easy as it seems. To become a successful affiliate you need extensive connections and engagement. To get engagement you have to attract people's attention. You have to become a content creator and create social media that can become an ecosystem where you spread your referral link. It's not as easy as it seems. What you need here is how to get lots of followers on your social media. It requires "capital" in the form of connections that have been obtained from parents or money to start creating content.
