If so, how much should I constantly trade to pay off these costs and gain actual profits?
Cant I be just a small fish following to that big scary whales??, as I am limited money and time...
Joining trading signals is fine but for a paid one? Definitely for me, not. You will soon understand why I said that once you get involved in bitcoin or any crypto trading and able to build experience out of it. You can do it on your own. You are spending money to get involved in trades then you will think again of another expenses just to joined trading signal group.
Like I always said, trading analyzations no matter how technical and deep it is will be useless once panic destroys the momentum. Signals are not always meant to follow but can treat as one of the good reference.
