One of the best features of Bitcoin is it's anonymity. This is also one of the reason why countries are banning or at least hesitant to embrace the technology. From money laundering to illegal drug transactions to human trafficking. We always blame the FUD from mainstream media, financial institutions like banks, the government etal. But do you think, the one that would "kill" Bitcoin is actually the nature of it.
Here's another news where Bitcoin was being used in an illegal activity. This will raise a lot of eyebrows because it concerns our children.
I don't think this will happen to bitcoin, maybe the only thing that can kill or make bitcoin stop is when there is nothing that humbles it, nobody receives it and uses it then it becomes useless
