I would disagree. Posts are only valuable on Steemit for the first few hours and first day at max.
Having an early boost from MSP and the bots seems an easy way to stay at the top of the Hot section of your topic. Or, even the Trending if you are lucky enough.
Waiting till the last minute might cost you some extra eyeballs, audience and future followers because your post fell into obscurity immediately.
Agree but 99% minnows arent as good bloggers like you ;)
