I do it to let my followers in who are not online every day. This way they benefit from more curation rewards. Also, some accounts will not vote on posts that have been artificially inflated.

I see very good points here. Promoting with bid bots after 1-2 days will increase the curation rewards of those who voted prior to promotion. Let's just make sure we provide valuable content and follow the rules. @grumpycat is in action!

That's my plan😁✌🏽

Depends on who votes when.
