Most followed trade-advice Telegram Groups?

Hello everyone,

I just tried to look for information from myself but it looked pretty difficult to be honest. I would absolutely love to find a really good Telegram group with loads of trade advices etc. The kind of groups that could have helped me to anticipate Bitcoin Cash x4 for example.
The kind of group that can serve as a base to decide a trade or not with my own analysis.
I am even ready to pay for a group like that.

BUT : There is SO much competition in the field that it's kind of difficult to know who to look into.
So my question is : what are the best telegram groups to subscribe into ? What are the ones that are the most trusted / followed ?
No interested to see advertising though.

Also, shall I look into other options (Slack for example) ? Is there a Slack Group in Particular considered to be a ''goldmine"'?

All answers will be greatly appreciated. Cheers !
