You're absolutely right. I was getting down on myself about how I'll be lucky to generate around $10 in post rewards right now, but thinking about how much actual STEEM you get from that - versus how much STEEM you would get from a post with $10 in rewards back when the price was at $4 per STEEM - is incredible.

Think about how much your curation power will go up if the price of STEEM goes back up! I've got around 3k SP at the moment, and it's not really worth much of anything in curation rewards. Meanwhile when I had only around 1000 SP and STEEM was trading at $4, I could upvote a brand-new article and give it anywhere from $0.02 to $0.04. Pushing up your SP balance now means when that price goes back up, suddenly you'll be a swingin' Dolphin instead of just a measly little Minnow.

Sticking around now and stockpiling STEEM/SP will benefit you significantly in the long run when the price of the cryptocurrency comes back up. Will we ever reach $4 per again? Maybe, maybe not. Who knows - maybe we'll take after Bitcoin and get into the tens or even hundreds of dollars in terms of valuation. Even if we don't, though, considering how you can gain STEEM and SP without actually investing any of your existing funds means that whatever the price rises to, it's all pure profit. Unless you invested at $4. In that case, well, better hold on for a while. ;)
