No bot can ever bring you a good profit.
Hah.Sooner or later they will begin to lose all your balance. And if you do not follow him, then you risk losing everything.
That's not really possible unless you completely screwed up the config settings.As long as you have enough for the bot to actually do something useful, they are well worth the price. If you're planning on giving it $50 to work with, you're not going to get far.
