Not necessary if you ask me.  IOTA is not the most legitimate coin out there but it's not a "scam" per se, nor is it a pump and dump - it's been trading peer-to-peer for a long time before this exchange release.

IOTA is shit because it requires proof-of-work from each client in order to have "zero fees".  This means that the IoT devices that it claims will connect to it will find it very difficult to use IOTA without doing the PoW, and the battery life would be bad.  I wouldn't recommend it, but it's a project which has been going for a long time and hasn't just appeared out of nowhere like people are claiming.
