The both possibilities are bad, and you will end up losing your money one way or another. Signals are basically the way people check indicators and tell you what a crypto "should" do, doesn't mean that it will do what it should, more often than not there are many coins which does what it shouldn't and go to opposite way.

This is why I am not expecting them to really have a difference, it will probably be a group that tries to make their money not via trading but more from the customers that come along the way. Anyone who charges you for indicators will know that it is not a guaranteed income and customers are a better way to make money from since it's steady method.
