Graviex comes from Russia in the year 2018. The exchange trades many crypto currencies ranging from 30-40. I think with the number. Crypto currencies supported the exchange will be liquid. The trading volume is also, impressive and the trading pairs are many. Well, I was not okay by the trading environment the exchange has, it seems complicated to me and the colouration is just plain and nothing else. The customer care never snub my messages, replies are been sent to my messages, with high sense of respect. I don't know why, some people are complaining on the withdrawal confirmation. I hope this is attended to, to avoid lack Of trust.
