If it isn't risky, what is holding you back from getting started?
It is hard to make a direct income from social media alone. If you are seeking for such a path, you will end up like one of the many millions of spammers out there who are blasting their affiliate links all over the place, making very little money (pennies) and making users of any social media service hate them.
Are you willing to consider other ways to earn that extra pocket money? Blogging, creating a helpful website, freelancing and selling digital products are some of the ways that people use to make money online.
