Powering up your Steem allows you to give great content on Steemit a higher vote. This in turn benefits you by giving you curation rewards, in time, growing the amount of Steem you own.

IF you leave your Steem as just Steem, it can't be used to vote for others or grow the amount of Steem you have. Unless you are just speculating or trading Steem, If it were me, I would power up most and save some for certain emergencies or even vote buying. Then again, that's just my two cents =)

Steem power is the determining scale about how much reward you can give some one. The more sp You have the more you will be able to reward others.. But the lucrative benefit of having more sp isn't always about rewarding others.. See based on the amount of reward other gets you also get some back for your curation as curation rewards. Means the more sp you have, the more you fill your daily upvote quota the more you will get curation rewards.. Gathering sps are for the long game that visionary users of steemit have.

On the other hand steem can be used as instant liquid tradable tokens..means you can transfer steem into other accounts whenver you want. Now keeping steem stored can also be profitable sometimes. You can sell them when market steem price is high and buy them again when the price is low. Its almost like how share markets work.

Powering up is like a way of investing on steempowers with your steem and that is also a way of showing that you believe in the steem

economy which means you are investing more on steem and when many people are powering up it

is believed they are investing into steem and they believe in it,this act alone will make the steem market experience demands and when there are

demands on the steem market it will make the steem price to be healthy and begin to reach more higher price...

your votes gets a big value and when you vote a whale , they can see your upvote because of high value and in return they might upvote and see your blogs and also follow you, also your reputation start increasing,

If you used your steem for power up then you have more voting power so you can get more reward. And if you leaving them as a steem on your wallet then they are not used for vote power they are just token and you can withdraw them any time any way.

Powering up will help the steem economy and the steemit platform generally,infact the more people

power up their steem the more steem will be
something that more people will demand and the

demand makes us as an investor to take profit on our investment,powering up is also good for the

person that initiated it because it will make the steemian to be able To earn more with their

upvotes so it is a win win for everybody and

everyone can smile to their investment,the more
