Right now I can boldly say that all popular crypto exchanges and platforms have impersonated scammers on telegram, if you are a newbie to crypto be expecting strangers texting you to fix a problem for you once you make complains in the official channel on telegram, beware
Telegram is the most widely used scamming method by scammers, as telegram is very easy and safe to use. In this way, the scammers add fake accounts in the official groups of different exchanges for the purpose of scamming a new member. If you ask a question in the official group of an exchange, one of the scammers will DM you. They even opened a fake account in the name of support of that exchange. This is a really dangerous place for newbie.
