You all should buy steem power because it's getting more power on your votes and each year that you keep your steem power you'll get more steem power at the beginning of the next year.
SteemPower gives you the equivalent of an ownership stake in the Steemit network. 15% of all new Steem created is given to holders of SteemPower. That means you will see your SteemPower balance grow. For example, if you own 100 SteemPower on January 1, 2017, you will have 115 SteemPower by January 1, 2018.
