You guys will drop your Jaws when I will write about what I discovered two days ago. I can now confidently tell that on Bitcointalk there is a group of scammer who work together and whatever they make, they share in between them. They study their target very well and every text they send, they create opportunity to scam their target multiple times. Today I have some work to do so I can not write the entire experience. But I am glad that I was not scammed anymore, there was a good possibility for me to get scammed again from the same group of scammers.
Let's take it step by step how I understood it:
The scammer created a group chat in which he added himself, the person he was impersonating, and you. He was then successful in tricking you into believing that the real user (who you know and trust) needed some money and a reason why you should sent it to them. You believed that the person you trusted was asking for the 0.019 BTC, so you sent it to them. In reality, you sent the bitcoin to the scammer.
It's more than that now. I will try to write about it soon.
Cheers,
