Scammers are found almost everywhere this days. One just need to be extra careful when dealing with someone you don't know. For OP, just accept you have been scammed. Trying to communicate more with them may complicate the issue and you may later fall into a more bigger scam.
I am sure that if strangers approached him on the street and asked him for money, he would refuse. But at the same time, he treats with confidence all the messages that come to him through telegram and is ready to give his money.
Wot gives the you the assurance that stranger is not a scammer. Scammers don't upgrade this days that they can do anything to get money. Imagine people turning themselves to beggars for the sake of making money.
