PEOPLE. That is the only thing that can destroy bitcoin. We are so easy can fall under someone's influence or our greedy and to make money through use of other people, all of that destroying bitcoin by little day by day. This destroy is not felt yet, cause of bitcoin is not so popular indeed, around 10-20% of people know about bitcoin actually. I think with raising number of users bitcoin is going to be in more danger. I can't say what is going to be in bitcoin banning or what else, but bitcoin is going to be destroyed by people and cause of people. That's the fact.

A jealous person like the ceo of some company called Jp Morgan or a country like China whose loosing the grip over Bitcoins tried to do shake it down but did not succeed, so what's clear is that investment bankers and government are against it, but then it has patronage of Japan to. So for me it's the bankers who pose the biggest threat, but we shall deal with them. Then one more looming threat is of the fork, hopefully we see no. More.

maybe its not who but what can destroy bitcoin, it strives ever since it started almost with no value then reaching to this point where it can be compared better than investing to gold. Maybe they will find some vulnerability in its security or destroy its reputation through ignorance and hoax.

I disagree with you. If governments want to destroy bitcoin then they will be enough to strengthen control over the Bank accounts and destroy the Internet exchangers. It's not very hard to do. That is why to strengthen the position of bitcoin it is important to be able to buy and sell bitcoin directly.

The same person/entity who can destroy the global Network of interconnections (i.e. Internet)

Is it possible to destroy Bitcoin market value or make zero value? Who is authorized person or organization?

May i know about it!

A major hack or fail in the code is the only thing I can think about right now. That would really have it down. But a thing like that would be like a major hack on the internet, highly unlikely.

Actually for my opinion the one or the ones who can destroy the bitcoin is Chinese, see what they are doing and whats happening to bitcoin. They are banning and not allowing ico's in their country, so whats the effect? See the fast decreasing of the value of btc. In a single country can destroy the btc what more if the other.

Anything that could destroy Bitcoin can destroy Internet. The governments could kill Internet but would be suicide, unless there is a global war.

Or if all the governments agree to control Internet like China does now. So if the world government becomes a reality, they could kill Bitcoin.

I can't see Bitcoin dying without internet shutting down or without a global government
