Name one system, piece of software, or physical item that has become unpopular because it was used by criminals.

It has been a wild time and the hype inflated the price with all these speculators getting involved. The price has been very stable since the crash, it is probably exactly where it should be without the speculators. It's a shame it had to happen that way, it was hoped that bitcoin would avoid a sensationalised media circus and the currency would gain strength in the shadows before going mainstream. The Chinese government hasn't been helping matters either, with their hostile actions. Maybe people will stop looking at it as a short term money-making scheme now and start viewing it as a legitimate currency.
Quote: "the killer that will be putting it under official jurisdiction. The lack of this last one is what makes it attractive to many people now, but there are US companies such as Sunlot Holdings that see a way to get rich by making it official currency, and government is likely to back such a movement."
That is simply impossible. If the government want to create their own cryptocurrency they can do that but they cannot take control of a system that is already established and depends on millions of independent users. Even if they somehow could take control of bitcoin, those people who don't like it can jump ship to another cryptocurrency.
