it could be when the most of the people will misuse openly and that for most of the country will ban it. ( It will depend on our usage).

i think this is out of the question, but I see bitcoin dying is far from reality, even if people will not acknowledge bitcoin, bitcoin will still be there and can be use for transactions, even if there is no internet, there are still LANs that is available for transactions of bitcoins, bitcoins being lost through your wallet or being thrown out because you threw your hardware, still you can recover those data. But if you are trying to say bitcoin dying, like people are not using it anymore, I think you need to check your history, bitcoin is considered digital gold, and there is a reason why is it so. Just look at gold today and its history, if everyone else knew that gold will be that precious, everyone will have it, not only major banks, but since bitcoin is gold 2.0 and everyone as of now can access bitcoin, we need to take advantage, it will not die, even if we don't use it, it will just increase more in value, and just like gold, its all all about supply and demand for now.

when no one use bitcoin, include price of bitcoin drop and alt coin price grow up. and when bitcoin die it will replace by other coin that have more people interested.

Yes if people will stop using bitcoin then the price will go down and then it will die but I think people will stop using bitcoin since we can use bitcoin to make transaction easy.

Bitcoin and blockchain technology just starting the revolution change of payment and financial system on the world's.
For me, still very soon for predict Bitcoin will die by the reason Bitcoin and blockchain are obsolete.

Bitcoin base on the developer and mining network. Since, we have the developer and miner working collectively, there's no reason why bitcoin will die. Therefore, one of the situation which could make bitcoin actually die would be if nobody was willing to operate the mining infrastructure or developing a new software.

I don't think that situation will ever happen, that will happen only if people stop using cryptocurrency which is not going to happen. This whole crypto community has changed the entire financial system of the world, which is for the betterment of the universe, this system can help to eradicate poverty and change their livelihoods.

I think bitcoin will die can be caused by the price is very down and the possibility of other altcoin that will replace it, and could also when the government decided to ban bitcoin trade worldwide

I have heard that if many governments ban it, it will be much harder for it to grow and go mainstream.
