Thanks for your comment Kris! Eventually almost all passive income sources has an end! If you got a fixed income from an article, then it’s not a passive income.
But in medium you can earn from a single article everyday!( not lifetime)
My friend earned an average $50 everyday from a single article for 2 months straight. Don’t you think it’s a passive income?
But I got your point. This is not a usual case. And you are right. To earn regularly, you have to write regularly. But the model of income is passive here. And good part is no one will push you for doing work like in the most active jobs! You can write whenever you are in the mood and earn.
