Greed is in human's nature so deal with it and if you are using this kind of knowledge like a kid then you could say that gold and silver are also the financial virus. There is no point in arguing this but yes bitcoin changed alot of people's financial. No one will be willing to kill bitcoin not because of greed but because it is not kill-able since this technology is way beyond every currency nowadays
It's not killable, but if the powers that be decided to ruined, im afraid they could to a certain extend, towards massive negative press, aggressive laws against holders, buyers and sellers and whatnot. They could scare a lot of people away and cause a crash. Of course, there would always be people that aren't pussied out by the tyrants running Bitcoin nodes and Bitcoin would survive, but as a underground currency, not the mainstream success we want. It basically depends on the people, if they want to keep getting buttfucked by the fiat system or support BTC no matter what. If no one gives a fuck about their laws and whatnot, there is nothing they could do without causing a massive revolution (they would to basically go inside people's houses and shit, and they know that wouldn't benefit them).
