Though from my findings from othe traders I was able to deduce that not all group signals are false that most times it works exactly the way they predicted and most time reversal.
think of it this way: if you were a trade genius able to accurately predict the price, you sit at home with your computer, do analysis and buy and then sell and make a profit, your life is perfect, you don't need to be stressed You're welcome. Now I ask you: why would a genius in trading be wasting time spending hours analyzing several currency pairs to send a telegram group constantly when that person could be trading alone and with the good profits he would have, he could live a long time well very quietly? it just doesn't make any sense. you could claim that he would do it for money he would charge on the telegram vip channel
but even so, it wouldn't make sense for a person who manages to earn a lot of money with day trade to need other people's money, and you and anyone else can see that these guys who send signals and have telegram channels that charge for subscription, they are very desperate to get other people's money, that's why they are constantly discounting the prices of subscriptions to the vip telegram channel, they don't make money with day trades, they lie. they make money with the subscription they charge from telegram vips channels
You are right that the main source of income from the paid / premium telegram group is the membership fee. This cryptocurrency trading market is risky and instead of doing the trades, they give their members paid signals. Now if the signal goes against their prediction, they have nothing to lose but if it goes in favor, they will announce everywhere, in their free groups in order to attract more people for their paid membership. They will never tell in public the signals which went into the losses or hit the stoploss.
No matter how experienced a trader you are, you can join these free groups to get some free signals and also update about the cryptocurrency news but do not join any paid group. That is what I personally do and will recommend.
