Hey Holm.
First of all, you know I do think that the price will go up eventually.

However, your reasoning doesn't make sense mathematically. You don't earn more steem for your articles than you did when the price was up. The reason for that is the following (I will use very simple numbers and disregard curation awards for this example):

Let's say a few people like your post. The payout is 10$. When the price was up at 5$, that meant 0,5 * 10 * 1/5=1 - you got 1 Steem. Now that the price is down, if the same people like your post, the payout will be 2$. That means you'll get 0,5 * 2 * 1(approx.)=1 Steem. You still get the same amount of steem. However, it is worth way less than before and so are the SBD you get.
So in short: You do get way less value for blogging right now. If you see the steem as an investment, you don't get less, but you neither get more (except for small effects such as less people posting...).

So what I am saying is, this is not a "bad" time for posting, but it is neither a "better" one than it was when the price was up. Let's stay realistic here :-)
