Discovered it from PundiX group. You may noticed that scammer using user name on Bio and he doesn't use any username. This is really confusing matter. If you are not familiar with this kind of scam then you might fall into this trap. Scammer might ask your personal details, private keys or may offer any bonuses. So be careful if you receive any greedy offer on telegram. Please match username with main group and verify it.
Most of newbies wouldn't think much and probably they might fall. So please share it with your friends.
Not new to me though. This is basic. Almost all of the low-life people/scammers uses this trick. In every Telegram channel. There will always be imposters pretending to be an admin or someone from the company. Always be vigilant and observant. Don’t answer those people who pm’s you first and always check the admin tag beside the admin’s name on the channel members tab.
