I really love the idea of IOTA. I am concerned about the longevity of it as a tradeable cryptocurrency, though. It has been a little while since I dug into it even though I do have some, but with so many new things that have been and will be added to the IoT, the price of MIOTA will have to stabilize. Otherwise, trying to keep a globe of connected devices up-to-date on volatile pricing will be a hurdle that it probably won't be able to overcome. Last I heard, they were finally trying to get a third party to get their wallet working. I tried several versions, and could never get it to work. That, right there, is a big downside to holding IOTA.
