As an incentivised author, you want to have some insight about how much you can make on Publish0x. With average earnings per tip dropping by some 40%, compared to end of March, we have some updated statistics on that. All data taken from the official Publish0x statistics.
Most tipped article for May 7 ('Bitcoin could reach $11,000 before halving... and fall after it'), earned $5.31 (at the time of writing this post). Zulonga has 368 followers and is publishing articles once in a while on Publish0x. This was his/her second most rewarding post (the most rewarding one earned him/her $40.03), but most of his/her posts make some $2-3.
Moving on to the week level, most tipped article was published on May 4 ('$300 in $DAI aelf Explainer Contest: #aelfexplained'), earned $6.44, at the time of writing. Mappo has 651 followers, and is publishing 1-2 pieces per week on Publish0x, earning him/her $2-4 a piece. His/her most tipped article earned $10.34, and was published back in March.
Finally, on the month level, most tipped article was published on April 21, and it was no other than the Loopring contest announcement, earning Igor Tomic $16.12, so far. Now, Igor doesn't need any introductions, as he's the COO of the platform. He has 2,550 followers, and his posts are earning some $3-8 a piece. He is publishing mostly platform announcements once per week or so. His top earning post was published back in December 2018, bringing in $22.39, so far.
We have seen authors publishing 3-4 articles per day, in hopes they will get $0.10-0.30 a piece. It's pointless. Publish0x is a small platform, with some 5,000 active readers per day. The most you can make in one day - if each and every reader for any given day tips your post - is about $10. You don't stand a chance getting any decent earnings for your articles, publishing a bunch of posts within a few minutes.
