If half of our planet get destroyed it means the other half will need to have steady energy source to power mining process and it will also mean the human who are survivors on the half planet must serve as  nodes for the network to function.  Once there is an explosion people will panic and saving a server might be the last thought that will come to peoples minds. If Bitcoin must survive a Nuclear war it relies on so many factors and the basics will be energy (power source) and the web

As for Bitcoin living on i won't doubt that but while it still lives it will get slower for transactions to get verified, cost of mining will multiply drastically, many nodes might forcefully shot down due to the attack and many will lose access to their wallet as explosion will destroy lots of valuables and documents. A big chance for the internet to shutdown completely

Nope, Not at all as Nuclear war has a lot of consequences. Stability cant be achieved in a nuclear war always remember not only BTC but also our all the technology, development, progress, and evolution cant stand against nuclear war as much I know remember the famous words, I don't know Which type of weapons are going to be used in WW3 but in WW4 there will be Axes and Hammer of stones.

No.

Cash and fiat will be useless after a society-ending war. The only things that will have value will be the things that keep you alive:

• Food
• Fresh water
• Medicine
• Shelter
• Bullets and other weapons

If you can't eat it, drink it, or use it to protect yourself from weather, disease, and hostile people or animals, then it's pretty useless.

• Gold? Largely valueless and useless.
• Diamonds? Largely valueless and useless.
• Coins? Largely valueless and useless.
• Paper/linen/plastic cash? Largely valueless and useless.
• Credit cards and debit cards? Largely valueless and useless.
• Bank accounts? Largely valueless and useless.
• Stocks and bonds? Largely valueless and useless.

I'm not even sure "cash" will survive. People will be hoarding more concrete stuff like food, shelter and ammo.

Nuclear war means the destruction of the earth, which means that everything will be completely destroyed. If that happens, we have more to worry about than the existence of bitcoin, like the famous Einstein quote that Hamza2424 repeated to us. The war between russia and ukraine is getting fiercer and more widespread but I hope they know what they are doing, especially Russia if they think of using small nuclear weapons to respond to Ukraine then this will also be the starting point of real nuclear war.

For me, this is impossible to happen right now even in the future. But if just incase it will happen in the future, I believe we are all dead by that time, or there is a new generation of people who will experience that and I don't hope it will happen.
Speaking of Bitcoin, for sure Bitcoin that time is already in high market cap and trading volume, trading stable or sideways without any huge dump or pump in just short period of time and for sure there are lot of ways to store your Bitcoin in the future which became safe even there's a nuclear war.

I think Nuclear war is the hight of it. I wasn't around in the Times of the world war but, I know of a local war that almost divided my country, we didn't have much technology then as we do now but, we had transitor radios, a few walkie talkie and early generations phones and it was the most , most forks needed to keep up with the news. Life was hard as it is with wars and I don't think, anyone in his right mind even if a part of the world's population would be running nodes or mining during those times.
Surviving is the first thing given the nature of the weapon at play and just being out operating a mine and having troubles with hit amongst others is what non would be readybto handle. Bitcoin's survival would depend largely on the survival of humans first but still would crash and come back up.

If nuclear war really happened, of course the most important thing that crossed our minds is how we can save ourselves and our families, because the most valuable thing is our own lives, and we only think about how we can fill our stomachs and what is certain is that we want cash to buy our needs for our needs during the war, in my personal opinion bitcoin will not survive if a nuclear war occurs, because it is certain that the internet will die, electricity will also die, if the internet is dead we will certainly never can access bitcoin again.

I was sure somebody was going to quote that, but that's just not going to happen.

Assuming enough population survives after this to start a new war, do you think people will suddenly forget how to craft weapons? Even if a nuclear bombardment happens in every city on this planet there will still be enough scraps, and enough raw materials for everything to start just in a few years as it was before, it's not like we will be reduced to monkeys! There are thousands of pipe guns right now in the world, guns that look like coming from a zombie game, that can be crafted from scrapyard parts but they are still lethal.

Just think, if a nuclear war happens will thousands of people forget how to melt iron, how to get coal, or how to build an engine? No!

As for Bitcoin, it's all a matter of the scale of what that war will be, and more important what surviving means.
A copy of the blockchain will survive, a few computers or hopefully a few ASICs to keep mining also, let's ignore the difficulty adjustment and others, but would that mean people will still find a use for it? Cause things like sending money in minutes on the other side of the globe from which a few nukes just came might not be a priority anymore.

I guess so. Bitcoin isn't tangible so it won't be blown into dust when nuclear bombs pulverize everything. They all remain in the blockchain. A copy could survive, which could later on be used to revive the network.

If the human race will survive a nuclear war, then people would begin to restore things right after. That includes the internet. But it might come at a much later point. First things first. I think human civilization would have a long time rebuilding itself. That depends on the scale of the war, though. But with human beings having the tendency to annihilate the world with their craziness, it could really be worse.
