@mavrek, welcome to Steemit, and thanks for your comment!

You're right, the "$" sign is a little confusing, and I have long pondered why there isn't a stylized currency symbol for Steem (the underlying currency of Steemit) to distinguish itself from dollars. Because that's really what should appear there, in a little round circle like the "^".

What I do know is that since the platform is created and maintained by a decentralized team of developers, there are also lots of little "bits" from older versions of Steemit that sometimes get overlooked. This would be a good point to bring up with the devs.
