Steem Power is influencing how much your upvotes are worth and as more Steem Power you have, as higher rewards other people & you are earning with your upvotes.
You can still earn Steem Power by posting articles & comments here on Steemit and the only other way to raise your Steem Power was to "Power Up" your account by buying STEEM and deosit it in your Steem Power balance.
So Steem Power is STEEM, you can withdraw it by "Powering Down" and you can never loose your own Steem Power by voting. Giving Upvotes costs you nothing, only the so called "Voting Power" is going down with every upvote, but it is recovering automatically.
You can always see your current Voting Power, how long it propably takes until it is completely recovered again and how much your Upvote (with your current Steem Power + Voting Power) is worth, on: www.steemnow.com
You can find another great feature on the website too: A calculator how much your upvote would be worth with a specific amount of Steem Power!
Here is the direct link to the calculator: https://www.steemnow.com/upvotecalc.html
There you can calculate how much you can earn propably earn per upvote with a leased amount of Steem Power, in addition to your own Steem Power. And now I will show you how it works.
Note: For leases that are 4 weeks or longer MinnowBooster offers leases of 185SP per STEEM per week.
Click on "Lease" if you are ready and you have enough STEEM in your Steemit Account for the amount of Steem Power you want to lease.
The STEEM amount will be reduced from your Steemit account automatically and your leasing request will be added to the "New Leasing Requests" list on minnowbooster.com.
You will receive a message when your request was filled and you will find it in your transaction list in your Steemit Wallet. If the request wouldn´t be confirmed after 3 days, the STEEM would be transfered back to your account, but the requests are filled very fast in the moment.
I think this is a great opportunity for all Steemians to give themselfes and others a great boost for a while and if the leasing rates will stay as they are currently, it could be lucrative a long-term re-invest opportunity too. In the moment it makes sense to always reinvest a part of the Steem you are earning with your leased Steem Power to lease more Steem Power, so that your upvote worth will raise more & more.
Im testing it since around 2 weeks now and MinnowBooster generally offers really nice features for Steemians, such as selling votes, delegate Steem Power to other users, or the bot etc... This are even great passive income sources for people with high Steem Power, but not so many time for posting/voting! Better than just storing STEEM in Steem Power, but not using the POWER of the STEEM POWER. :-)
