You hit it right on the head. Part of the reason why I didn't consider power up immediately was because Steem price was higher than I would like it to be.
If it will drop below $2 USD for an extended time, I will most definitely drop some money to power up.
When the price is high, I think that's when focus switches over to more authoring, etc.
I agree completely with your analysis @enforcer48! :)
Keep an eye on it and remember that this is a marathon not a sprint!
