Well i belief that all crypto signals are scam or fake, many of them are available on telegram but i detect they are using this signals to pump a particular coin and when people are busy buying they would have made their profits
Crypto signals are also not recommended by me. Even if there are many channels that are available on telegram, still majority is just fraud. Universal crypto signals, 4c-trading, infocrypto, fat pig signals and verified crypto traders are only the few ones that do not cheat people. However, the best option is to not take these very seriously. At the end of the day, you have to rely on your own skills.
