I only join crypto groups to buy potential coins, this makes it easier for me to choose which projects are good to invest in. If you want to look for potential coins, you can join telegram groups about trading, there are many groups that provide trading charts. Or you can learn on CoinMarketCap, you can choose projects below rank 200.
You should also note that the trading group usually shilling for a coin so you shouldn't just blindly follow their signal it's always better to make decision based on your own analyzation, their signal or etc is only good to make you know that this certain coin exists and nothing more.
Not to mention that telegram groups usually are by far the worst place where you can find many scammers.
- Not just telegram groups, discussion forums and social networks are also relatively fake about the information and potential of the project, the leader is just always trying to exaggerate and advertise the project while except for the form and a great promotion, the project has no value, so the safest here might only be our knowledge of the market. Sure we don't have much time during the day to get to know the project clearly but relying on the telegram team's lies is pretty good, the combination of information from different groups will help us to know the most accurate about the project
