Volume on Crex24.com is good but volume on Graviex is too slow. On Graviex, the spread of buy and sell prices are too big. You can not enter and exit the market on Graviex with the price you want, with profit, and with short waiting time.

Graviex has one thing I like too much. The exchange detect instantly any deposit in your account. Even a transaction is not confirmed on the network, it will still be shown in your deposit history. It is a very cool feature on Graviex.
