I dont. Most signal dudes get paid from shitcoins and dump on you the moment you enter.
You don't have to rely on all signals of a sure because they may disappoint. Signals can work but not for every time and everyone don't like or know how to study to use it. Some expert traders are advising not to follow all that a signal show you and to be careful. To use money that you won't regret is better as I'm reading what others say.
Obviously the signal will only use its members to do something and then it will be discarded before they announce it on their signal channel, therefore expert traders will clearly be very against this because it is more of a scam that they seem to randomly provide opportunities where to be buy a certain coin price.
So usually premium signals always have a down payment to join, I have also been offered like this before but I refused because I don't want to depend on the uncertain, if it's true that they have more ability then it will be distributed to close relatives not by making group signal and prepayment.
