Many have already tried and many have already claimed Bitcoin was going to be destroyed at some moment, but it has never happened for real.
Then the question arises, who have the ability to destroy Bitcoin? Ironically, the answer may be only the person who created it: Satoshi.
It's curious to think about the scenario where the creation goes too far away from the initial purposes of the creator, so he ends deciding to nuke this.
And how can this thought be understood and applied to reality? Of course Bitcoin won't cease existing, but as things go more and more centralized each new day, empowering and giving control to the groups who have been ruling this world since always, Satoshi can compromise Bitcoin's credibility, by for an example, dumping all his coins on the market at once.
Despite the fact that some people have claim that Bitcoin will not be existing one day, yet it still exists. The government can shutdown other things they can control like company or websites, but that’s not easy to do when it comes to bitcoin. The success that Bitcoin has proven over past years shows that Bitcoin is more stronger than we think, to the the point of thinking Bitcoin can be easily destroy one day. No one can control the price of Bitcoin, it means that Bitcoin is not depending on anyone.
But let’s put imaginary things outside and focus on reality, since we probably not seeing bitcoin getting destroyed lets focus more on grabbing the opportunity it has brought us than find what could destroy.
Sure, all these imaginary stuff should be put behind, because we all believe that anything that is capable of destroying Bitcoin will not to be easy to get. Many individuals have accepted it, and most of their savings is in Bitcoin.
