It's a shame that people consider murder to deal with personal issues. It's good that the killer wasn't hired, though. As for Bitcoin, I don't think the means of payment should be emphasized. What's bad is the killer part, not the Bitcoin part. But when Bitcoin is mentioned in such stories, the content of the story casts a shadow on BTC reputation as well. As if killers aren't hired with USD.
There is no killer...

It's a scam. People that kill don't work on the internet.
You have to be stupid to hire a killer these days. Most of the adds online are fakes set up by the police and you can't even be sure if the guy won't scam you.
It's really funny why there are people who think that hiring killers online is legit, though I'm not really sure but logically how are these people gets the job done especially when you're from the other side of the globe. And yes, if there is going to be a killer for hire online that could be just an entrapment operation for the authorities trying to capture some criminals online.
What would she say? I hired a killer and he didn't do his job?

The story is really shady, I don't get to see the source, could have been a made up story. I'll buy into this story once a credible source shows up.
I'm pretty sure authorities have better things to do. Anything that is extreme that you see online is a scam. All that scary stuff is just made up for entertainment. They do make good storied. There is a tv series about the darkweb stories. Yes, its made up but its still fun.
