is there any restrictions on how many shares per day on facebook? and any limit on maximum no of shares from Nauticus posts ?
I am also participated in a main bounty, is that same shares counted for these mini-bounty also?
The only maximum is 500 NTS earned as a maximum. If your posts are of high quality or enough effort, they will count.
Activity from the regular bounty will not grant stakes in the mini-bounty as well. They must be different posts.
