This is really making me worried.
I mean we are investors of a cryptocurrency and we all know that Bitcoin also has a feature of anonymity and if that already happen, what more to people that don't usually know how to secure their wallet and even their identity? We should really be careful with the information we are sharing on the internet, it could be really dangerous if people know our information. We are not just putting ourselves in danger but also our loved ones.
I don't think that the anonymity of bitcoin is involved here. Maybe the suspect was close to his place or one of his friends that he knew that this guy is making a lot of money and because of the jealousy for the money, he tortured this bitcoin trader for hoping that he will get his money and all of his bitcoin because we all know that 1 bitcoin is worth a lot of money.
