I dont think that freelancing is the easiest way to make money online. Imo the best and easiest way is affiliate marketing and kindle. I have many affiliate sites and i earn good money in a passive way. I have some work to setup all and then i have to wait for the money. In kindle also.
I work as freelancer too, because i have some knowledge in SEO, Marketng, PHP and HTML , but this is no easy money. You have to work very hard as freelancer.
