Trading signal channels in Telegram are really not good for your money since what they are doing is either post a pump and dump coin or just promote their “premium” channel which you need to pay either one will just make you lose more money in the process since they are just only thinking about their profits and not really about helping you. My advice is for you to learn actual technical analysis and do your own analysis for any trade since it is really better to trust what you have learned then just follow what they are suggesting blindly.
Now that's what we need to learn, technical analysis, it needs to be learned if you are serious in understanding, you will understand, I have also been offered to join premium signals with the notes that I have to pay every month, but I reject the offer and I want to really learn from analysis own technique.
In trading it takes time to understand and don't continue to rely on premium signals to trade.
