I don't think that Bitcoin as a Currency will die. Remember Bitcoin is not a company promised you to increase your income and it is not for business and also it is not for a profit oriented. It is a digital currency for buying and selling of goods and services. Bitcoin has come to stay, and I also don't think that Bitcoin will bow down for fiat currencies because nobody control it. Either the fiat currencies will bow down for Bitcoin. The individual Countries can't tell the users of the currency to stop using it.

The video your provided is just to damage the good Image of the currency. Various Governments have tried their best to eliminate Bitcoin but they can't. Therefore, for Bitcoin to eventually died, that means, the whole internet will be dead.
