You either make your own decisions through research and thinking, or don't trade at all. These "bitcoin signal" services are 99.9% pure bullcrap anyway. If I could predict bitcoin prices accurately, do you think it would make sense for me to announce my "predictions" in a group? Of course not. I'd take advantage of it for my own.
To think up sensibly then we would really think of this way.If its possible to predict bitcoin prices then getting rich would be easy aspie.
Lots of so called pros in trading giving out lots of speculation and even selling out their signals which is total Bullsh%t actually. Better to study on our own which is more worthy to do than relying to these kind of services.
