1) Don't blindly trust signals, take your time to access and verify it.
2) Do your own research(DYOR), coz it gives you confidence and control.
I would place my points on this that most of us as traders are always bent on signals and then we get everything bursted while some traders will always rely on friends opinions and decisions about a coin without doing our own research and findings. So it's high time to rewind and restrategise on this issues.
