Did this woman trust an unknown person on the Internet to share personal data with him without knowing more information about him? I mean, identifying the man using the available data is easier than tracking Bitcoin addresses, which may require court papers to recover your money.
Regarding Bitcoin addresses, they will most likely end up in a central wallet, but without starting legal investigations, you cannot ask these services to recover her money.
That's probably what's happened, scammers are good at social engineering so I don't think that they had a hard time having to convince her to do this kind of thing. Also, isn't TeamViewer works like a remote access tool right? I think that's how they've got that person and has stolen her funds. Regards to the possibility of investigation, I don't think that even if there's one, it's unlikely that they're going to ever recover the money stolen, this is a syndicate in my opinion so you'll have a hard time finding the group or even arresting any of them since this happened online.
Yes, i think the same ...
