Not all who are in club75 and club100 build up their sp. From what I have seen and heard, some are there to get support and after a while will sell out thier accumulated sbd. I have seen a lady who is getting massive support because she is in club75, but she hardly power up. She will convert like 140 STEEM and power it up then continue getting support. When I compared her power up with my own, I noticed that me tat is in CLUB 5050 has made more power up than she does. And guess what? She is now in club100, while accumulating over 135sbd. What is her plan? I think majority should be placed on those who engage more in Powering up. Not those who does not withdraw, power up less and accumulate the rest.
