I was interested, I even registered on their site. Until I realized that their coin is overpriced. For 1 ETH I would get 401 DELTA. 302$/401 = 0.75 cents per DELTA.
No thanks.
It's a approximate number. The exact number of DLT you get is based on the actual price when they sell your ETH.
I got 0.50 cents buying with NEO
