Well I wrote articles and did affiliate work for about 10 different start ups. A couple of them never paid .... a couple others paid but their coin never ended up on any exchanges and then there was others that I made decent money from. For example UCASH was pumped hard when it first hit ... I made $1250 + from doing articles for that project. I wrote two or there articles and made a dozen MEMEs for MRK coin and was given $500 worth of their coin ( the value since has dropped drastically but at the time of payment they were worth $500 ). So as you can see it can be both lucrative or a complete bust.
