I'm thinking of a long term investment in steemit, what is your advice?

I believe steemit is a great initiative that proposes a new model on how we share and value information.
I want to invest and support this initiative.
Though I don't want to play the popularity game. I love to share, i love to write but I'm a bit lazy to be playing a game of standing out.

I bought some STEEM already, though I don't know if this is a good thing.
Can anybody give me some advice on buying STEEM, Steem dollars, or steem power?

Thanks I will appreciate.
