This ressonates perfectly with the First of your posts that i read. The one where you provide examples of steemians that for big from nothing.
I have been here for only 1 month, but what i have seen so far os huge.
And there is a lot of ways to grow here, not only blogging. You can also contribute to opensource projects, invest, curate etc...
I cant say about the Future prices of steem, but It definetly have space to grow big.
But we gotta keep an eye on what is happening outside. Like bitcoin, steem is the First of its kind, but something better may also appear in the Future.
