Marli, the good thing you already have a Steemit account and want some Steem Power in order to get more value on your votes for your posts and comments, I’ll show you step by step how to buy Steem Power.

If you do not have any Steem available in your account, the easiest way is to go to BlockTrades and buy your Steem or Steem Power there.

Select “Steem Power” at the right and the crypto you will use to pay at the left. Then enter your Steemit username and it should confirm it’s correct displaying your profile image.....well that's how i can you
