Where did I/O Coin come from?

I've been checking Coin Market Cap lately to see how Steem is doing. It's been pretty stable for a while now, which is fine by me. I just don't want to see it fall a lot so that people lose faith in it and Steemit.

Today I see Steem drop a place as I/O Coin has jumped 1100%! I don't see any news about it today, so what caused this? For any currency that's an incredible change.
