Hello guys. After checking for quite long time, I see there's no single reliable Telegram ENG group?

Let me clarify what I mean - I saw hundreds of ICO, bounty, investment, signals, whales, P&D, etc. groups - 100% of them are scam, don't have anything useful or created just to get advertisement payments by reposting news, nothing more. In Russian it's almost same, but not 100% - 10% of groups are really good, professional, authors do very good analysis (NEVER SELL SIGNALS - if you see someone selling signals - ITS SCAM), either from fundamental side, from technical side, or from other aspects. Is it really so bad and trashy in ENG TG space?

Happy to see recommendations, unless its about bounties, DeFi, HYIP, ponzi, signals, ICOs...
