Telegram is a place where scammers dwell, that is telegram is the home of scammers currently. I have seen them appear in different forms just to get your attention. They either come as football tipster that you will need to subscribe to their channel and be paying to get weekly game to play, or crypto expert that will want to help in educating you about Bitcoin and trading. Its left for you alone which one they will scam you from. It's a funny encounter but a deadly One,
It's not just scams that you can see on telegram app since it's easy and fast to use the app. I also received messages on telegram if I am into crypto and also messages if I am willing to buy forum account or willing to sell forum accounts that are hero member rank or above. I tried searching the telegram handle on the forum to see if the person share his/her telegram handle in the forum and will know what the person's forum username.
This is why its too dangerous because people tend to message you of things that you are not into, even asking information and also inviting you to join in a group you don't know, that is why i automatically block people who send me random message, because i know what they want, its either they will send a link, or something that make my account compromise, and steal info, don't put or use telegram sending critical info like wallet keys , email password etc., just to be safe, because we never know.
