I keep reading that Gunbot is only for Poloniex - this is very old information.
Gunbot nowadays supports trading on Binance, Bitfinex, Bittrex, Cryptopia, Kraken and Poloniex - and support for more exchanges is coming very soon.
Since the project started, it grew a lot, feature-wise. When it started there was basically one trading strategy - by now there are over 25, and these are all fully configurable to adjust to your own preferences. New strategies and indicators are regularly added, after a rigorous beta test by a large group of testers.
From my personal experience, Gunbot performs just great. I get 0.5% gain per day, measured over about a years time. Many users do even better, as they invest a lot more time to manage their bot.
