Although that is right, I wonder if their signal can be used for a long-term investment since many coins can be hidden gems. Besides that, it is difficult to search for that group because what I see on the telegram, many of them are just copy paste from other VIP groups so that will work for the long term. And do not forget that those groups need you to pay for their services so I do not recommend joining. That is why you better learn to analyze the market by yourself so you do not depend on that groups and you will have a chance to improve your skills. But that will be up to you.
I agree with your opinion that maximum channel post copy signal, but its means not that all Channel follow this, i follow some youtube Channel those provide signal from their own analyze.
But still, it is rare to find the right channel that can provide a signal from their analysis. Maybe I am not as lucky as finding those signals from good telegram groups. But I also feel grateful because of that, I push myself to learn trading by learning from many trading lessons. If I do not do that, I do not think that I can make a profit as the market will not be the same from time to time.
We need to keep learning to improve and not just use the other people's analysis because when they can not provide the signal, we will find it difficult to determine the coins to trade.
