I'd say it's market manipulation, someone with money wants to drive the price down before the new updates come out. Grab up the cheap steem before they launch tokens...

With tokens STEEM becomes one of the most useful chains there is, on top of already being the most globally used (according to transactions).... It will hit that $10 mark each... And go up from there...

Also take advantage of the lack of posting, makes it easier for your post to make it to the top!
