The Steem price hit a high of $4.55 mid-July while the number of posts per day hit a high of 10.659 posts per day at July, 19. Both highs were almost on the same day. Since then, unfortunately, both the price and the number of posts per day went only downwards.
Yesterday, there were 3.015 new articles submitted. Far below its peak, but still a lot more than the average of 325 posts per day back in June. The same is true for the Steem price which was about $ 0.30 in June and currently trading at $ 0.80.
The correlation is clearly visible in the charts.
