Hello @andrestales,
I'm very active in the world of the crypto but yeah this experience of steemit is quiet new for me. So as always in any project, invest some little money can speed up your work. This is why I bought some steempower with bitcoin.
You can do this in your wallet, in the steempower section -> buy.
I'm not here in steemit to earn money but to raise my reputation so yeah I could have buy some steem or steem dollars as well but my priority is currently steem power.
