As I follow the link you shared, it is like the robbers and the victims dont understand what bitcoin is all about
I think there is misunderstanding about the cryptocurrency,
«The brothers searched randomly in the market to buy Bitcoin. The gang lured them claiming they can sell them Bitcoin.
http://cryptozona.ru/dubai-police-use-ai-tech-to-locate-and-arrest-gang-suspected-of-1-9-mln-armed-bitcoin-heist/---Why in the world, the brothers who are victims went to market and plan to buy bitcoin?

? Bitcoin is not something you can get or buy or sell in the market
Correct me if im mistaken with this issue.
