A trading signal will not help him to much. if he have not any basic knowledge about trading or if he/she haven’t any basic knowledge how to analyses the the token chart. If he is not aware of these he will not be able to distinguish between genuine and fake signals and this will certainly put him in a grave danger and at some point he will lose his investment by following wrong signals.
And this is the paradox with signals, someone that doesn't really know enough about the markets is not going to be capable of distinguishing when the signal they were given is good or not, and as such the signal is completely useless to them, but someone that actually knows enough about the markets to make this distinction also has enough knowledge to make their own analysis about what's happening in the market and create their own signals, making the use of those groups completely useless for them
When one can do market analysis then surely one gets an idea about the up and downs of the market. And when he receives a signal from a trading group, he is able to analyze it himself and feel how profitable the signal is. So I think a trader needs to have basic knowledge of market analysis regardless of which group to take signals from . otherwise he will never get better profit
