Well now about my experience with Graviex.net. The only exchange who has listed the coin till now.
Got enough coin when trading ABS for BTC at Graviex.net. 70 dollar cents each on average but when trying to withdraw the minimum amount of 0.001 BTC , they took 40 percent of it in total. They multiplied the fee by 20 times, the horror! When i withdraw the BTC they said they would ‘only’ take 0.2% fee of it.
I strongly advice not to trade with them. ( Graviex.net ) after this experience. I know it’s the only exchange who has the coin listed right now but nevertheless.
