Dont try to use bots, they are a waste of time.
In fact, i used to buy preconfigured bots a long time ago, they all were a waste of money and time for me, i could never get them to work.
Some people say like what you said, but others not. Maybe bots will really work if we set it right. I actually not really know system of bot but my friend use it and say that to me. When we right to set bot, can make profit to us.
Bots do work if you configure them correctly. I've been using Gunbot for quite some time with some custom settings I've been testing for several months and I'm making a profit on most days with it, though I'm still working out some kinks daily and changing settings as necessary. Nobody's going to give you a (good) profitable strategy for free, because if that strategy was so good, why would anyone give the strategy away for free or for a low price?
I will definitely say that they're not for everbody, though. Even if you're already a good trader, it does take some time to figure out how to use and configure the bot you're using properly, and there's no guarantee you're going to make money with 'em.
