I do not think bitcoin will suffer destruction because over time more and more people are using bitcoin to perform various transactions or just investment. only one thing can destroy the bitcoin ie the internet. bitcoin will be destroyed if the internet can no longer be accessed and it will be impossible.
I think for now this bitcoin is not a problem to be a disadvantage. Because the bitcoin is the most profitable and also have the best future. And keep in mind, the internet will not be lost or destroyed. Because basically bitcoin is a digital currency is best, and it's certainly the internet will always be a place to update and expand. So don't ever minded bitcoin will crumble when the internet is lost, because surely the internet will never be lost. Continue working and never surrender to face everything.
I think bitcoin reached to that stage which is now not possible for anyone to destroyed bitcoin because now bitcoin is not alone there is huge quantity of users who support bitcoin and also such a big and develop countries are going to support bitcoin so I think there is no chance for anyone to destroyed bitcoin and even hackers also.
