So, I tried Fiverr a while back, just to see if it's actually something to do as a freelance artist.
Within a matter of days I already felt it was a bad deal.
…And it only went down hill.
After those couple of days, I had managed to do some jobs. Though after each of the ones that I actually finished, something happened. For example the buyer decided to ask for a refund. Which basically means he ended up getting the whole design and I got nothing.
This ended up happening almost every time. So I tried another page called 99 design, which was just the same, but maybe worse – since there you do also compete with other artists before getting the job, which means the buyer can take all the ideas for free and cancel the job afterwards.
My conclusion is simple – it is not worth the time.
In youtube, there is lots of similar experiences.
