steem power is one form of power your steemit account has, the higher (more) steem power an account will have a big influence on the popularity of the account in the eyes of steemians, having a lot of steem power certainly greatly affects the strength of an account's vote, even some whale many SPs just sit and sell their upvote for business, and there are also those whale who give upvote by filtering quality and classy content without sending SBD or Steem.
So you have to understand that Steem Power also affects the bandwidth power of your account, if your Steem Power is very sufficient you will not think about this problem again, but for beginners this problem is a serious matter, and they must control themselves for that by keeping bandwidth due still lack of SP owned.
The steempower safety point is above 500 SP
Why did I say that? if you already have a 500 SP you can already give your voting power below 100%, you can set your Voting Power power by giving up the amount you want, this is what I say is a safe point for those of you who have SP above 500 and can continue to control the power of your voting power you give upvote will appear scrool what percentage of the sound you want to give to an upvote.
