I understand what you want but it is very difficult as you are looking for some kind of secret information that can easily help you to do this and this does not exist, the only way to recognize if a coin is any good or not it is to know about the technology behind cryptocurrencies in a profound way, if you do not know this then you are just gambling with your money if you invest in those altcoins, so unfortunately I do not think you have what is necessary to achieve the results that you want to get.
Indeed, some people just joined the signal groups because they think that this is the answer to their call to make rich. But unfortunately, they don't notice that these people are milking them from their hard work money. Because the reality is that these signal groups have to do nothing with us, they make their own analysis which we can make it as well.
But I could say that trading is like gambling and the result it is either we gain profit or just lose.
Misguided after many people want to get rich quick, they want to enter the paid premium signal but the reality is that we are slaves to what they say, we always agree to buy it if we think about it with reason, what do we do? we can also do that more in depth and know how altcoins will react with TA and that skills must be able to trade not just want to be easy with crypto signals you will be stuck just relying on it.
For me if they still believe in crypto signals then their money is at stake, but if we do that we can only anticipate.
