TIX is for the Traffic Insider Tribe or the #trafficinsider tag. I never figured out the focus of the tribe.

The coin has a very shallow distribution. There are a few accounts which seem to upvote each other's posts. The accounts on the trending page get tens of thousands of coins for each post ... but they are always the same accounts.

I guess you have to be an insider to get the votes.

The TIX coin trades at 0.00000096 HIVE.
