You don't have to buy Steem Dollars to crank your Reputation up. I never have invested in SP or Steem Dollar.
Whatever I have right now is just by posting. I know its not much and this is because I do not give much time to my Art. I know I could do better than this.
And you don't have to worry about the account, it will grow. Just post good and original articles, Donot steal content from the internet, Share you views on other people's content that you like and can relate to. All the best and Happy Blogging :))
