The thing about the pob richlist is that old people are giving up on pob and new people are believing in pob and staking but old people are unstaking.
Those who powerdown will soon regret thier actions when proofofbrain post an update about the community.

"The race is not for the Swift but it's for those who endure it to the end"

It might look as if stakers are loosing and sellers are gaining now but later staker and holders will rejoice and reap thier labors(I hope so soon).
What proofofbrain should work on is to entise and create what would encourage stakers not to powerdown and for new people who are yet to stake should stake.
