I could have subscribed to your signal service but I am also afraid that you said you may ask for fees for the signal in the future got me a little worried.
This is certain if op didn't mention it to you. It is usually the practice that signal group ask subscribers to send payment for the different levels of package that users entered for. They have tasting time which maybe by the week or monthly. The challenges layed down for such signal groups is it is still speculative all what they do and they gather users to pump the coin and sell before you do.
Yes am very much aware of the way signal group operates, sometime they give free signal services to their subscribers just to let them test they service and most time the trial version tend to yield minimal profits but if you are looking g to gain good amount of profits then one must be ready to pay.
Speculation is an integral part of the cryprocurrency market and as such signal group play a vital role in most coins price moment so I agree with you on the ability of signal group to pump the price of any coin their are supporting.
But the dilemma that I am seeing here is that most signal groups even paid ones, will give signal a lil bit late than the actual action.
This is why, some are getting rekt with signals because only the owners are getting good profits.
It is fine trying the free signal groups, as you are not losing anything from this try-out.
However, if it is a paid one, you have a lot to risk. Not only the subscription fee but your money that you will be used for trading purposes.
In this case, try to learn on your own. Slowly but you have no one to blame but yourself if anything goes wrong.
You can start small and learn the tricks. At least, after this, no one can steal what you learned and experienced.
