The are many free telegram group give you free trading signal, but i believe this is not a good way. Their signal's sometime worth, but it's really hard for us to follow. You should use some premium signals, that give 70% chance to win the trading. If you interesting, join Rose's premium channel, she have good warning before market crash, trading signal, some Gem also...
Signal groups aren't that accurate and you will only get more losses and the only people that will make money out of them are the signal providers because they are artificially pumping up the prices or dumping it and they can just go for futures and choose which suits the situation.
