Very interesting! I think that to many people post here in cycle with the price of Steem - e.g. when the price of Steem is down they post less (because they think that they are earning less) and more when it rises. It shouldnt make to much of a difference when you post and if anything you should be posting more when the price goes down (less 'competition' for the rewards pool)
Im still waiting for this big price increase weve all been waiting for, but in the mean time I just keep on Steeming
