I have been using the bot for a couple of months now, and I should say that it works. The dude that runs the bot is very helpful and tries his best to help me with the issues that occur. One thing I would recommend the buyers, is to get the poloniex version first, cause okex exchange itself is run by very "unorganised and irresponsible" people. Another positive thing for me in particular, is that the bot made me study ubuntu and now i now some commands:D. Yes you can run the bot on windows vps, but linux vps are generally cheaper and ubuntu is not as hard as I thought, internet literally has tonnes of forums, plus BzCo has made a full video on youtube on how to start the bot in ubuntu.
