I think main reason will be low demand, and low demand itself might be caused by different other issues, fore example legal issues.

One of the main reasons could be political decisions of governments, if they will ban bitcoin, or set restrictions to it, which will influence the market.

That could be much more dramatic, because it's very probable that there would be still people trying to use it. Although in this case if the bug can be solved, the blockchain can be started again, although there would be, for sure, a big price crash. There are some countries still don't legalize Bitcoin and they even admit that the person who invest Bitcoin is a criminal. If Bitcoin is ban in every country, it will be an extinction of Bitcoin. However, it is impossible and it won't happen in the future.

Bitcoin can easily die if the government will have an order that the bitcoin and other cryptocurrencies will be no longer allowed to their country and that will become the start for the cryptocurrency to die and have its end and that is my main reason why i am not putting all of my money into cryptocurrencies because there is still chances that they could die.

Well, maybe when the situation began to lose confidence in the bitcoin users. people tend to leave bitcoin, because bitcoin is no longer provide benefits to users. but, I think it will not happen, because bitcoin will always provide many benefits to the users if we use it properly.

That is one of the major possible situation to happen that will make the life of bitcoin to an end. If there will be no development or even upgrade for bitcoin then it will be impossible for bitcoin to just continue living. I think that the banning of the government will be a huge thing in the future because even though they can still use it, they will be having hard time in using it which is just useless because you will experience difficulties too in cashing it out because of the law that the government implement to a certain country.

There are multiple situations where bitcoin can disappear, but all there are in relation to a lot of other stuff going on. Let me explain myself: if there is a really great attack on the internet, maybe all transactions could die, as well as a lot of other uses of the internet. If internet falls for a couple of hours, will be the same when it restarts again?

What I mean is: Cryptocurrencies are a part of the internet. They are here to stay. They can’t be just banished, they can’t disappear. Humanity already has created it as an important part of how we see the internet, transactions, money, fees…

So, the only way I can imagine cryptocurrencies can disappear is doing so along with the whole system.

Bitcoin will die if the people will stop to patronize the bitcoin. I am really sure that bitcoin will die in that situation but I think it is really impossible because I know that people will not stop patronizing bitcoin because bitcoin has many benefits to the society.

The only thing that will kill cryptocurrency is lost of interest of the people who are keep on believing in bitcoins. There are a lot of consumers who already invested tons of money in this industry so it was very far from dying and do not think about bad things on bitcoins because it will surely have a bright future and every one will earn a lot of profit.

I dont see any issue being able to let bitcoin die, there are thousands of milions invested over bitcoin, i doubt any of those companies that had reached Roi they will let the most profitable investment to die due some issue. We are facing the split of opinions at the core, something that damage bitcoin, but this were inevitable, since we are different.
