I agree with your sentiment if you are looking at steem like a stock. STEEM is akin to a dividend paying asset, and the cost basis keeps going down. The problem is that if you are looking at STEEM as something to power up and as an engine of value creation, you should be laddering down your purchases. This is especially true if you anticipate the price recovering even to near term highs and you are regularly participating here. The more you have in the interim, the more you will get back in rewards.

I'm looking forward to see what happens to my curation rewards when HF21 comes. The fact I have been dollar cost averaging into STEEM means I will just get more of them.
