I had no idea on this one so I read everybody else's answer.  :-)
The answer must be 2%, because everybody else says so...

2%!!

2%!!

A, 2%

A) so you have 10 Votes a day for free ... 20% generate a day... 2% loss at 100% so its 10 Votes a Day for no losing powers ;)

2!

A.  Roughly.  It never seems like it's perfectly even.

I believe it's a) 2% :)

A) 2%

A!

Answer is A!

a) 2%

A) Answer is 2%. When I was a new member of Steemit, I did not know that my voting power was something that could fall. I voted for every good post I read, even comments. I felt myself that I had contributed something to and rewarded good things. It was, of course! What was the point of being stingy? This has continued for a while. When I saw when I voted and there was no total win effect, I stopped there. What was happening? Then I searched that the voting power as a minnow was quite low. It was a very sad situation. It's been rough in about a week. Then I learned that an upvote of 100%,  reduces our vote power by 2%, and that it took 2.4 hours to replace it. So I had to give a maximum of 10 votes a day. After I learned this, I continued to be more selective. This is such a moment.

A)each time you post your voting power decreases by 2%. That's why if you vote 10 times in one day, it'll drop you to 80% voting power, which will take one day to regenerate. If you vote more in a day, your voting weight drops more, but also takes longer to regenerate.

A)2%

A is the correct option. So a 100% vote takes 2% of your Steem Power. You recover 2% every 2.4 hours, that's a 20% daily. You can give 10 votes every day. When you reach 500 SP you will be given the slider to give a lower percentage vote with this option you can split your vote weight as many times as you wish. Like 50 votes of 20% a day.

Respuesta a, 2%

### Final answer:  a) 2

I believe this to be the answer because early on someone told me not to upvote to the point of going below 80%. They said that was about 10 upvotes a day. Therefore using grammer school  6<sup>th</sup> grade math:

<center><h1>100% - (10 x 2%)= ?</h1></center>
<center><h1>1.00 - (10 x .02)= .80</h1></center>
<center><h1>100 x .80= 80%</h1></center>

I have shown all my work. Thank you for letting me play!

A- 2%

I'm gonna go with 2% as well. I've read that around 10 votes a day are possible at 100% voting power. Doing some quik mafs, it means that each vote reduces around 2% power.

Cada vez que utilizas poder de voto a un 100% vas reduciendo el mismo en un 2%. Lo ideal sería votar hasta que tu barra de poder llegue a un 80% para de esa manera puedas regenerar tu voto más rápidamente. Y puedas continuar votando con suficiente valor y de ese modo  ayudar a tus amigos y demás usuarios  e interactuar más eficazmente en Steemit.

A 100% upvote reduces VP by A) 2%. When I go on a voting spree I often drain my VP into the 70's. I am okay with this, because I don't have much of a vote to begin with and I'd rather support someone than worry about my VP :D

I know, I know! The answer is a, 2 percent. I remember this one because that is the same as the percentage of my body that was replaced with secret alien technology.

A) 2%!

Its A!
