Chatbox is home of trolls, I never use that in Trading, unless I'm on the mood to troll someone too (lol) or when I am having my pastime. Group signals is helpful when you know how to nurture it, how to derive the equations that's been given by professionals, and if you basically doesn't do anything as a Trader, you know, you are being a baby that is always being spoonfeed by others, then don't expect something great.
Especially the one on Yobit. There was a better one on BTCe but that's long gone.
It's a simple truth in trading that poor people read all the guides and analysis they can get and they are still manipulated and barely earn anything. Rich guys don't need to read TA all they need is visible on the chart as they go and the big supply of money they have does the rest.
