the sign you used in your post ($ sign) is called dollar sign and generally it is used for United States dollar. but the number you are reporting is not USD valued. it is Tether value!
in other words 1 bitcoin is worth 7200 Tether which is equal to about 6500 US dollar.

I'm a bit puzzled about this...
Bitfinex is showing 7200 (right now) and those are $ not USDT , are they using USD for their tether?
We're going to have another gox?
