Residual income or passive income, I used to have that when my YouTube channel and my blogs were earning. The minimum I receive is $100 per year for each of them - blogs and YouTube channel. But when Adsense had become strict with their new policy that is restrictive my YouTube channel stopped earning and my blogs were also not earning that made me lose my motivation to write. Now it's been years that my blogs are inactive although I sometimes upload a new video on my YouTube channel.
