I am using this bot and it really works,
I am using it only on one exchange with very little money and it was able to generate some extra income,
The guys running it are really nice and helpful, they will answer any of your questions.
You basically have to do nothing, just put some money into one exchange, give them your api keys, and relax, the bot will work and you will make money basically doing nothing.

I recommend it and i advice you to check out this bot, it has potential if they develop further.
