3 years (since Sep 2016 til now) and counting. 0€.
Building my own project from scratch. IDK if this is the right thing for this week's topic, but it answers the question.

I do have my paid 9/5 tho. But the code I write after is my personal and it's not yet bringing me any moneros.

It seems it's gonna need at lest another year, so next Nov it'll be 4 years w/ 0€ :) Maybe even some -x€, since I'm horrible at design - will prolly have to hire someone to do it for me
