They can never shutdown bitcoin or make it disappear like that. I think there are many people, especialy from the financial area, who would like that Bitcoin falls and vanish from the scene. But this is not going to happen, you can't stop the future. Bitcoin is very well established so far and can't just "die" over night. Bitcoin and cryptocurrencies are the future and pumps and dumps in price are normal and they will not destroy the Bitcoin network.
no, of course to die like this without leaving a trace of bitcoin can not of course, like the entire crypto currency in general. But it can get into the process of stagnation for several years, in view of the fact that the advantages of its use do not cover its disadvantages. We will have to wait for new breakthroughs and we will have to accept this.
