But you can view this a loop. Say now you earn more staked SPS as you have 4x multiplier vs a 1x multiplier and this gets compounded into your staked SPS and you earn more staked SPS and so forth. As long as you don't extract SPS, your Rshares will continue to grow + more chests. This change basically attempts to stop people selling SPS.
