It is a bit more complicated than just buying and selling. We also make currency just by using the platform. :) So yes my account value has steadily been decreasing, I've almost kept it flat lined though just by the fact I post and create content.

Would I love to see it hit $4/steem again. Most definitely.

I believe we can make that happen, but it'll take some effort on OUR part as steem users outside of steemit/busy. I posted my thoughts on this in my most recent blog post.
