HitBTC is absolutely fraud and trickster. They made on twitter a voting to which coin they should add to exchange ( Verge and DGB). After voting they said they will add both cryptos!
But already 1 month passed and they did nothing about. They keep silent and not answering people about when they will add two coins. In my opinion it was a dirty trick. They want to add more traffic to exchange. SO remember they can trick you anytime.
