So 600 STEEM a week is earning $1200 a week currently. You would need to earn that every week as the increase in signups happen. Plus you are taking away 600 STEEM POWER from yourself each time you do it that could have been used to increase your future earnings. My point is you aren't increasing your stake in the system but instead lowering it over time. It is definitely an opportunity cost involved in powering down. And there is no promise that you will continue to make the amount you are as the user base continues to grow and new changes are introduced.
