I am a little late to the IOTA game but have noticed the same thing. I decided to cut my loses and trade off my IOTA coins for fear of losing my complete investment. After research and finding out the makers of IOTA can stop trade at anytime, I sorta feel like they are a scam. On top of that, most of Thier rumored partnerships are just that... rumors.
