What is Voting Power/STEEMPOWER?
Because you earn $$$ on Steemit.com for upvotes, they limit how many you can give.
Voting Power is a % to represent your remaining votes. Each UPVOTE will reduce your Voting Power -2%.

Voting Power Recharge
Your voting power will regenerate at a rate of 5% per 6 hours.

So each day (24 hours), you will receive +20% of your Voting Power back.

Voting Power Effects $$$ Upvote
As your Voting Power % lowers, your upvote will be worth less. Try to keep your Voting Power above ~70% if you intend to vote daily.
