Nope, working harder does not increase your odds. Engaging more WILL get you more votes from amr008.pob for the engagement project so there's that.. and by being consistent you always have a chance.
Just enjoy it and see the rewards as a bonus. Stay consistent and you will earn some
that is what i am also saying, been consistent will help you increase your chance of upvote
of course engagement we give you more chance to be chosen but I bet you it is not really by the amount of post or comments you write it is just random here
