YES I sell steem power not Steem - Explanation:
STEEM - Steem, tradeable tokens that may be transferred at anytime.
Steem can be converted to Steem Power in a process called powering down.
STEEM POWER - Steem Power, influence tokens that earn more power for holding long term and voting on posts. The more one holds the more one can influence other’s rewards and earn rewards for accurate voting.
Steem Power is non-transferrable and will require 2 years and 104 payments to convert back to Steem.
Unless certain sense I explained what I sells.
