Here is my little review about GUNBOT. I've tried it from 26.12 till 02.01 and, in fact, all I can say that this thing is working and working great! I've tried to use gunbot on ETH, ETC, XMR, FCT, ZEC, MAID, NAV. A week before the new year was pretty volatile, but gunbot has done its job – I’ve got little profit on all pairs!
I can not mention the perfect support from Gunbot team on all questions from installing to trading. P.S. I've tried to run gunbot on macOS and it works perfectly smooth, just as on linux.
