This is a very dubious and smart strategy, we ought to be careful online especially on telegram, alot of people are going extra miles, thinking of anything possible just to scam others. I will say not everything you see online is true, be careful even when you feel you just want to help someone.
Scammers are very wise, they love using Telegram among all the remaining social media because they catch victims always and they imply several strategies on telegram which help them in achieving their goals.
This strategy used by this scammer is an old strategy, they have used it several time, now they are trying to bring it back so that they can get newbies that are yet to know about it. Some of them do even clone exchange and ask you to login for them to take some percentage of you help them withdraw their funds; all these are strategies to scam you. Be wise and stay away from any message from an unknown user on telegram.
