IF war with China should happen this summer with the UNited States,,, could China hack Bitcoin if it had to regardless of cost?

What do you mean by "hack bitcoin"? If you mean it is about the 51% replay attack, the short answer is it is possible. Most of biggest bitcoin mining pools are located in China mainland. However it is only the short answer.

Chinese government acts like a dictator so they can almost do anything they want in their nation but the fact is they recently emphasized about their ambitions to build up a good blockchain-based industry so it will be odd if they take over bitcoin network and do replay attacks. Bitcoin is decentralized and publicly for all globally so if there are anthing wrong in China, and come from Chinese government, their reputation will be destroyed more. It is not what they want to have after so many offensive activities on them globally.

The world nowadays is much different than 10 years ago so the government will not be able to hide and cover all of their shit shady actions (if they do that).

Firstly, I have no idea how Bitcoin entered the scene between the war between those two countries. Secondly, define what you mean by "hack". The 51% attack is possible yes, but most likely would not happen. Other than that, I'm pretty sure it's close to impossible for BTC to be hacked. That is unless China hides their own quantum tech. Also, the Chinese government hates(or at least has negative sentiments with regards to it) Bitcoin, hence they themselves pronouncing their very intentions to adopt blockchain technology in their country and the production of their very own cryptocurrency or the so-called digital yuan.

What will be the motivation of China to do that? I think attacking Bitcoin Network won't benefit them at all.

If they want to get more bitcoin, then it's useless because people will sell their bitcoin immediately if an attack like that happens. But if they just want to mess up the network, what is the benefit for them?

I'm not really sure about that, even we still don't know for sure about where the coronavirus came from. At least I still haven't found a journal/legit source that states that clearly and it will be very helpful if you tell me if there is.

1.A war between China and USA will never happen.They are both too dependent of each other.
2.If such war happens,Bitcoin would be the last thing China would care for.
Bitcoin is still too small and taking control over the Bitcoin Core blockchain won't damage the US economy at all.
The only people and businesses that are about to be damaged by this move would be the Chinese mining farms and the Chinese companies that produce and sell mining hardware.

A 51% attack on Bitcoin is possible since China owns most of the mining pools right now but I don't think that they will get any benefits from it.

Instead of doing it, they will just let Bitcoin be. I don't think that Bitcoin can be hacked right now but who knows in the next decades :D. One thing more is that US and China are somewhat fighting with each other right now but I don't think that it will start a new war between them. Anyway, lets just hope that it will not happen or it could start the 3rd World War. :X

You did consider WW3 as a factor but not a threat, if ever two superpowers would go to war at each other then, data mining and bitcoin would be out of question because that war will ensure total mutual destruction and what happens when they both use their nuclear capabilities, the whole world will feel the impact and there will be electro magnetic pulse that will cause the disruption plus the fireball and the raditation after that, full scale war will remove the worth of many things and that includes cryptocurrency, in my opinion China would do that to buy off allies that will help them, in a war of attrition I do not know who will when but let's hope that it will never ever happen.

That's right, if there was a war between China and the United States, it would actually mean the beginning of World War 3, in which there would be hardly any winners given the types of weapons that the two countries possess today. Bitcoin would become quite irrelevant in the event of a world war, people would save lives and the internet would become inaccessible to many.

However, a world-wide war is very unlikely, because it costs a lot, has extremely destructive consequences for the economy and society, and given nuclear weapons, it would probably take us back to the Stone Age. I think the world’s superpowers have a much more important job this summer than the war, and saving the economy is currently the number one task.

AFAIK those mining pools are only technically located in China but the govt doesn't control them. Pretty sure if something goes awry then those farms will prolly find a new place to mind in peace.

I don't see how these two are connected. Why going to war has anything to do with a 51% attack? While the latter is theoretically possible (but it's so costly and would have such disastrous effects on economy that I don't think anyone will ever attempt that), it can happen without the war with the US. And speaking of the war, I am more than sure it won't happen. The war needs resources, and the world is getting into the global economic crisis right now. Not to mention how the pandemic could play out with armies moving around. And some said it would go nuclear, but it's also not necessary. While they both possess the means, they also understand the outcome of using those means. So even in case of a war I don't think there's a big chance of nuclear missiles being used.

This doesn't make any sense. War between China and US and Bitcoin, how is this all even connected? It isn't.
First of all I don't see a reason for war between China and US and despite rather bad relations between these two countries, wars don't start so.easy and something like that would probably turn into world war.
Also, Bitcoin doesn't have any relevance in regulations between these two countries so I can't see the point.

I think you mean 51% attack here. And why would they do that though? Just because they are at war with US? doesn't makes any sense at all, what will they get on crippling the market in short amount of time? Do you think that by attacking bitcoin they will win the war? It's not bitcoin that they are at war with, it's US. So I doubt that they will do a 51% attack, they should save that money because it will cost them millions if they attempted such attack.

War doesn't have any connection with bitcoin. Both are different thing. But Chinese domaince 51% of mining pools, so they can drop bitcoin price but that wouldn't going to benefit for them, rather that would be harmful for their economy

Will you still think about that?
Ain't making a bunker the first thing you should be thinking about instead of having deep thoughts about crypto currencies?

Hacking bitcoin?
I doubt that.
When you are at war, you get a weapon. Not a keyboard.
Or is this a discussion about "keyboard warriors"?  ;D

Coming from a simple person's point of view, I don't think that can be possible. However, this can be interesting to think about and if one day China can do that then that can be the doom of Bitcoin. Anyway, I do not believe that there will be a real war between USA and China as both countries may find it a big losing battle to both sides doing it...eventually these two giants will settle their difference behind the lights of the cameras.

In my view nobody can hack the bitcoin blockchain since it's fairly distributed and nobody owns it so it's not possible for anyone to hack it. In case of such global war, btc can continue to exist.

The war between China and US are economical. As US tries to marginalize China, it is trying to create it's own economic bloc. China won't go with a full fledged war against US cause it knows it can't win over US military. And in case of US attacking China, China would want to prove it to be the right one, an attack on bitcoin would be against it's image correction strategy. And also if more than 50% of mining power is coming from pools from China, it doesn't mean Chinese government owns them all.

Yes, that is true. But if the war gives impact to everything we have, then that could have a connection with bitcoin. Imagine if that war destroys everything, including internet connection or communication in all countries, I am sure that will give impact too with bitcoin. Bitcoin or cryptocurrency will not work well because we cannot connect to the network or use bitcoin and the other coin.

I don't think that they will drop bitcoin price if that war happens, but that could be possible if they know where is the mining pools locate so they can destroy or eliminate the company. That is only a scenario which we don't know if that will happen or not, but we need to prepare for anything that might occur later.

Lol, To much netflix could create fantasy so better minimize watching that since in real life there's no one will notice on bitcoin since if you look on current situation even if there's no war still we can see it unnoticed by many chines and american, only the techie or people who always stay on internet notice this so it's impossible for your claims to happen since no one can hack the bitcoins itself. Maybe the war will make bitcoins price go cheaper but still no one can control this even if the war happens.

It will make sense if we only talk about the two countries dispute but adding bitcoin in between? Meh.
What these countries are conflicting about is all on their economy, USA as the world's largest economy by GDP is such a huge advantage of them and they would not let that be on China's hand. On the other side China is world's largest producer which is the best competitor in the world that's why Trump is creating trade barriers. Even though the USA is a wealthy country, I don't think they will be still an independent country in the future.

What good would it do if China hacks Bitcoin? Bitcoin doesn't belong to any country.

If you mean being able to hack Bitcoin by the use of 51% attacks, which is pretty much the only attack that they can execute, then you're wrong. In terms of the global transaction volume, Bitcoin isn't used by any government as a store of value. It would make sense if you could paralyse another country by restricting their financial flow but it can't be the case. The most that they can do is to stop the citizen from using Bitcoin which doesn't really affect people since most of the transactions are in fiat as of now.

Simple answer... no.  As we can see China will rather focus its monetary fund for warfare than spending billions of dollars hacking the Bitcoin Network.  It is illogical to hack Bitcoin in the middle of a war.   It will only hinder China's war campaign than help it with funds if that is what you are thinking of asking the question about the possibility of China to hack BTC.

First how will war happen ?we are in this crisis and you are talking about war ,this is not the right time to tackle such thing because even
china is helping US and other country to prevent this pandemic so please stop this kind first at least after this Virus .

How could China hacked bitcoin and what is the connection of war in hacking?if war is there China will stay focusing about how to beat
 US and not to Care about Bitcoin or whatever.


there is no topic about stopping bitcoin existence instead bitcoin being in control of one country,things that very impossible to happen
 because no one owns bitcoin ,it is decentralized and cannot be handled .

Firstly, I have no idea which Netflix movie or show you are referring to here. Secondly, the governments would probably try to gain control of BTC since it is basically money in a digital format and money wins wars.

Op does have a point here. Even if BTC is decentralized and doesn't belong to any specific country, it is still money which itself is the most important resource when waging wars.

The Chinese government could actually execute the 51% attack if they possess their own quantum computers secretly hidden away. The same could be mentioned about the USA. BTC could prove to be a valuable resource though the scenario that op described seems impossible.

Bitcoin is not fiat though. It isn't a currency that is endorsed by the government. If anything, fiat is the resource that would be used during war. You probably won't see governments paying contractors in Bitcoin during a war. The spending during a war would take hundreds of billions and I highly doubt Bitcoin in its entirety would be able to finance even a significant portion of it.

Attacking Bitcoin through 51% would be a waste of resources and even if they manage to attack Bitcoin, it would quickly become worthless and all their resources would've gone to waste.

IMO, there are two types of war the cold and the hot war and if we're referring to a hot war then Bitcoin has nothing to do with it since everyone will have a life full of fear like doomsday for anyone. Cold war can destroy a country in fact this covid19 can be considered as an attack of china to the US and other countries that causes severe damage to the economy.

The Cold war with regards to hacking Bitcoin and I think it has no great effect nor be beneficial to china for it is still less of the global population are using Bitcoin or cryptocurrency right now. Either hot or cold war that may happen between the US and China will still the people who will bear all the sufferings.

Even if there is no war Bitcoin cannot hack or crack bitcoin, it's already a thing to hack bitcoin, and there are countless offers of money to hack or crack bitcoin but until now no one did even in other altcoins there are also offer to hack it.

Why does the war need to start? in the two countries, we know that no one owns the bitcoin? do the US or China own bitcoin, either way, there are so many theories about this who really own the bitcoin or what country it is. Still, I think bitcoin cannot be hack by anyone I believed this is a piece of advanced technology we might need more years to hack it.

This is exactly the only logical thing that can happen and I think a lot of people fail to understand how the world works when they hope and dream of black swan events like WW3, or a complete collapse of global economy, or total fiat destruction -- all in the hopes that this means Bitcoin is left to tower over all other money, valued at $1 million or some other number.

Not saying million-dollar Bitcoin's not possible, but that it would never happen in any of those global destruction scenarios. Food and security would be worth any number of Bitcoin we'd have if shit went down like this.

Thank you for your answer. You seem to see the larger theater given the conditions I proposed.

People and their wild imagination.

Gone are those days when armies fight directly. Now days no e of these countries can afford a full scale war. They can only put economic restriction and encourage hacking each other's military and secret servers.

Bitcoin does not depend on outside world issues. If the chines by any means are able to control the Bitcoin network then the community will basically can destroy them by ignoring Bitcoin.

Just like what happened to Steem Network.

Well, the said 'war' between these giant countries has been known even before. They both have huge resources and intel, but we know US still ranks no. 1 in the economic label (if not shaken by the pandemic). So China, being a competitor, knows how to attack. And I think, China need not to 'hack' Bitcoin. Most of us are aware with the fact that China had the plans and independence to use blockchain, and create their own cryptocurrency. Though, there are users of Bitcoin and other cryptos in their country, still, they saw a great opportunity with these coins, and to be able to defeat US in terms of the economic ranking, well, they have their own method.

There's a high chance, considering they own a considerable stake of the bitcoin mining pools.

Even if you assume some of them are semi-independent, you can trust that the communist government under pressure will use its authoritarian powers to force their will as most authoritarians do but what will the benefit of it be? Who knows.

If your grandma had testicles would she be your granddad?

Does my question my question seem stupid?

Your question is not stupid but it is pretty much not worth answering.

BTC is worth 180,000,000  180 billion dollars.

China has a multi trillion dollar budget.

BTC is a small fly on the wall.  Okay  a small mouse on the floor.

Would you be looking to kill that mouse if a tiger was in your house.

FUCK no you would deal with the Tiger.   Killing off the mouse and giving it to the Tiger won't help you very much.

Also if China really went to War directly with the USA and the rest of the world just watched it happen  most of the world world would die. Nukes would get used since USA has 333,333,333 and China has 999,999,999   USA loses the war if it is with knives pistols rifles

So that leaves biological  weapons or chemical weapons or nukes  any of them just fuck up the whole world.

So don't worry bout it.

They cannot. This is unrelated to Bitcoin, as Bitcoin isn't "American". Even various countries banded together to attack Bitcoin, they would not succeed. Annoy yes, but not destroy Bitcoin. It was designed to resist such a thing since the beginning, when it was though all the govs and banks would go against it (they didn't).

Funny thing is, if China went to war against US, they wouldn't attack Bitcoin. They use it too you know? I don't see what makes you think Bitcoin is somehow American, when many American politicians and bankers and rich people hate it...

Attacking Bitcoin is costly, and the more you try, the more you spend. It would bankrupt your economy before you could achieve anything. So forget it.

I don't think anything will happen. I don't see any possibility of an end to the war yet. No country wants a war. War means two countries being destroyed. It doesn't want a country in the current situation. The whole world will go after the crisis.Not only China and the US will suffer here. Bitcoin holder in almost every country in the world. The whole world will face economic recession and risk.

Do they really want to have a war? I personally will never imagine about it. It may be the third world war in the world? It will cause many things to this stability. And I don't think it will happen this summer, moreover, right now, every counrty is doing a war with COVID-19. So, I am sure that they will not choose to have another war in the country.

However, If they really want to have a war with the US this summer and they will hack the BTC for cost, they should have done it from a year ago. Preparing costs for a war is not something easy and short. It should be done from a long time ago in order to get enough funds. And the fact is that Chinae doesn't do that. I am sure that The two countries have their money to start and finish the wars.

The next questio is about hacng Bitcoin? What BTC? What owns? Or from the mining? China, we know that most miners come from this county. And when they want to hack BTC, they will be able to because most of them are also smart enough to this kind of technology. However, I don't think that the other hackers and people worldwide will accept this because it doesn't only affect the US but also to all people in this world. I am sure China will ever do that.

hack bitcoin makes me fell like it is a company or central system when some one know all bitcoin keys and will use them to hack all the network.
if WAR III starts bitcoin will rise to 30000.
it is better to say China ban bitcoin not China hack bitcoin because no one can hack bitcoin.
China banned bitcoin in the past and they can ban bitcoin mining but they need more people to invest and make more income from taxeses

I don't understand what you really meant by 'hack bitcoin', but if war should happen I believe China will be in charge of Bitcoin, as they right now have the largest Bitcoin mining capacity up to 50% of the mining capacity with US a accounting for just 14%.
And I'm scared what the price would if any such situation. May be 3 times what it is today.

But if you truly mean 'hack bitcoin', I don't think it is possible as it cannot be hacked by anyone

What do you mean bitcoin hack? I don't understand why bitcoin hacking included the war of China and the US. I can't understand what you really want to say or to ask if you want good feedback and well answers on your threads, you should make it clear, you shouldnt create a one liner post because there would be many people who will misunderstood what you really want to say, just like this one, we dont know what you want to say because bitcoin hack was included to the war of two countries, which is really not related.

I think Bitcoin will be neutral, so it's impossible to get into a war between China and the United States. And what are the benefits from China
if hacking Bitcoin, unless an economic war makes more sense. Who managed to have a lot of Bitcoin can controlled the economy in my opinion,
because in the future it is likely that Bitcoin already functions as a global curreny. So many financial transactions will use Bitcoin.

Chinese miners, not the centralized authority control 50% of Bitcoin mining capacity. So technically "hacking Bitcoin" is impossible.

"miners" also don't control anywhere near 50% of the mining power.
there are mining pools that are aggregated hashing power of many individual miners that control 16-17% of the total hashrate at best.
there are individual miners (mining farms) that produce a much smaller percentage of that hashrate and connect to those pools.

not to mention that even if some entity owned 100% of the hashrate, the still can't "hack" bitcoin.

The Chinese government can't hack bitcoin to control its price because it is tough for someone to access its network due to the support of blockchain technology. But there is no perfect technology that has a high security, so there is a chance for bitcoin to be hacked in the future. And it is impossible for the US and China to have a conflict in the middle of the pandemic.

I am not really sure what a war between America and China has to do with Bitcoin but to answer your question no. Bitcoin is not owned by the United States. (Atleast I do not believe so) There are alot of people out there who believe the CIA created bitcoin. I personally do not believe that to be. IMO why would the CIA create something that is so hard to be tracked?

What exactly do you mean by hack bitcoin? Like steal all of the private keys to every wallet with a balance greater than 0? Or hack each addresses location? Bitcoin has yet to reach a Trillion dollar market cap. They would be lucky to get 1 Trillion USD worth of bitcoin if they were to steal EVERY wallet with a balance!

I believe it Bitcoin could be hacked it would have been done when BTC hit 20k. But I also figured people with wallets that mined blocks of 50 would have sold at 20k. I mean I would have... But I guess thats why I am broke today! :P

Countries can do whatever they want, but this would never happen since they don't have adequate control over it's infrastructure/printing.

Best case scenario they'd create an altcoin and manage that.

obviously all policies of course the state can to do with what can be done, because the state has the highest authority in taking action for the greater interests and for the interests in all priorities.

but all the policies that the country does are certainly very measurable and considered good and bad before taking action, because the impact that will occur could have caused something greater than what was done.
it is different if it is the individual who cannot do it by the government, maybe only the policy that needs to be regulated so that it does not have an impact on the country as well.

"A 51% attack is an attack on a blockchain by a group of miners who control more than 50% of the network's mining hash rate. Attackers with majority control of the network can interrupt the recording of new blocks by preventing other miners from completing blocks."

" The attackers would be able to prevent new transactions from gaining confirmations, allowing them to halt payments between some or all users. They would also be able to reverse transactions that were completed while they were in control of the network, meaning they could double-spend coins. "

- Source : https://www.investopedia.com/terms/1/51-attack.asp

A while ago it cost about $481,233 per hour to perform a PoW 51% attack.. How much bullets can be bought for that amount of money or even medical supplies or other weapons.  ;)

The reason why they would want to attempt it, would be to destroy people's confidence in Bitcoin and not to steal anything with a double spend. By just performing at 51% attack, people would lose confidence in the technology and the they would start dumping it on a large scale. The price of Bitcoin would take a massive blow and it will effectively impact the global economy. (Businesses built around the technology will go bankrupt and exchanges will lose liquidity and trading volumes will collapse etc.) 

Hack Bitcoins ?

 I do think you don't realize that Bitcoins is actually something that is most likely non hackable if I may say.
 The security of your Bitcoins depends on you ' some factors like:-

- Which wallet company you choose
- Does your mobile have third party non verified apps
Stuff like that greatly influences the security of your Bitcoins itself.

I do think we should realize that , no country can hack Bitcoins , due to Mining farms being located dominately in China , what they can do is , seize the Mining farms and then at the end of the day reduce the hash rate.

- Which would mean , in the future if a war breaks our and the hash rate declines the transaction might become a lot less safer .

*Therefore they won't be able to touch the existing Bitcoins but they can for sure make the future transactions less safe*

I am wondering the same thing. Well, maybe OP is thinking that powerful countries will get as much resources as they could so that they'll be on the lead if war begins. But actually, the question is not specific. It was a little bit absurd :D.

Anyway, let's put in this way. If powerful countries will engage into a cyber war I am still not sure who would win. We know that there are also many chinese geeks lurking, russians are good also but americans got Walter O'Brien (https://en.m.wikipedia.org/wiki/Walter_O%27Brien) tho lmao (alright, enough movie marathon).

I guess that is absurd, there is no reason for China to hack or attack on the bitcoin network, bitcoin doesn't belong to a country either America or others, a trade war between them doesn't seem to have anything to do with bitcoin, so let it separate and don't connect bitcoin from the war between the two countries

idk how would they hack bitcoin? its like asking to hack every computer in the world. its nearly impossible , they called it decentralize for a reason ^_^

That is not what the OP is telling, if you look at the bitcoin network majority of the hash rate comes from China and the government can take control over these mining farms and control the entire bitcoin network, what you do not understand is that bitcoin is decentralized in nature but majority of the hashing farms are centralized and if you control these major mining farms you can control the bitcoin network.

If you think of those possibilities, WW3 is less likely to happen as many sectors will become really affected and become useless. Money will probably become nonsense as this war can make most of the people die. All currency will become valueless once US and China started to bomb each other's territory. This will probably bring a long-term destruction to humanity and to all industry.


Just don't be too anxious about that because World leaders are not that dumb enough to not prioritize the safety of its people. Governments right now are worrying about their economy above else, they are worrying about inflation, cryptocurrency adoption, and this pandemic. US are struggling right now, while China is really not that affected in this pandemic and they have a stable economy compared to other countries.

A war to break out between United States of America and China is not impossible to happen. When this happens, it would cause a huge impact globally for sure. However, I agree with others with that being said, what is the connection of the war to Bitcoin. I want to commend you for having a constructive imagination but as far as we know, for years now, Bitcoin has gained popularity but not as huge to be used as a weapon for a war of economy.

I do not understand your question, what is the relationship between the war between China and the US with Bitcoin.
After all, nothing until now has been able to hack Bitcoin, therefore Bitcoin is trusted by many people. I am sure
there will be no war between China and the US, we all have the same enemy the corona virus. So now is not the right
time to go to war.

I agree that there is no chance of a war breaking out between these two countries. Also, massive effect internationally will be taking place by then and none of these countries could ever survive without huge damage and loss to their resources. I also agree with thoughts of others, what is the relation between the war and Bitcoin. If a war happens, I don't think that china would be focusing to other things beside war strategies.

Assuming war erupted and China manipulate mining farm to attack the network, what will happen next then?  Would it bring more fund to China's war campaign?  Does anyone realized that once the Bitcoin Network is hacked, trading activities will be halted?  Let's assume that China gain a control over the Bitcoin network and produce millions of BTC on the new chain, who will then buy them?  The effort of China to cease control of the Bitcoin network will only be in vain because, once the hack is known, all demands will eventually stop living China with worthless bags of "BTC".

A 51% attack can hack a single transaction but keeping the attack on and hacking one after another requires so much resources that even a country like China would have a problem.

Also they would need the hardware so to get it they would have to steal all private mines in china and make it work for them. Also they would be losing money because even if they got some coins out of it the price would crash by the time they'd be able to sell.

If China is going for war then they will first take over the mining farms situated in China and there are plenty of them who could very well do the 51% attack and then the most popular ASIC manufacturer is located there and with all these aiding them do you think mining hardware would be a big issue. We have developers monitoring everything and if there is a hostile takeover then we will have a fork and kill that chain.

At this point of time that we are still facing a crisis, it is impossible that a war would arise for we are already on a deadly scenario and conducting a war would just create a massive destruction and would not give any good. Also, people will surely not get to participate for their concerns are more on health related. Also, even if such thing would be possible to happen that a war may arise between China and United State, the war would be mainly because of different political stand and regarding other issues which will not concern Bitcoin so basically they would not give a care for the hacking of Bitcoins once a war arises between those two big countries.

The short response would be no because there is no valid and strong reason to do such and why would they even care about it if the reason of the tension between them are mainly to political issues and other concerns that are needed to be attend to.

US and China will hold and keep from their safe ground, it's not the best time to make this thing happen.

With the pandemic virus that still hurting countries economy,

even china have now the power for sure there's still many factors
that needs to consider before taking to this kind of situation.

For me china can't hack Bitcoin for sure bitcoin have highly secured system and war? I think war between China and Us are not gonna happen for now maybe someday but for sure bitcoin gonna guard their system so don't worry 😉

51% attack is theoretically possible, but why does China need it?

I think hacking bitcoin is impossible, if this is possible then the value of bitcoin would not be what it is today, if China were to go to war with those countries then the price of bitcoin would rise sharply because fiat would lose its value when war happened

Indeed. Bitcoin cannot be hacked by China or other countries because there is no third-party control over bitcoin due to it's decentralization that bitcoin's price is only being controlled by it's supply and demand. There are also no war that will happen between US and China because we are in the middle of crisis that a lot of bad things are happening in this world besides the pandemic of COVID-19.

If China has the resources to do so then they can hack Bitcoin if they like to but if are lacking some resources then they will face some
problems if they will try to hack Bitcoin.

China is the biggest country but with regards to technology, I am not so sure whether they are superior compare to United States. Anything can happen,
so I cannot give a concrete asnwer to this topic as of this moment but I am excited whether it will likely to happen or not.

With the pandemic that we have, I don't think these powerful countries are thinking of going into war. For what? They need to prioritize their people over ego of something. People are dying and suffering because of this pandemic, and they want to go to war? I don't think so. And China can't hack bitcoin as it is decentralized. Unless, they will hack a crypto exchange and get their bitcoins' holdings. But there's no need for that. It will just ruin their image to the world. They have their own wealth already.

I agree. The leaders of both countries will surely take good care of its citizens first before thinking about their egos regarding political issues that can be fixed through humble negotiation and there is no need for a war to arise for we are all still suffering into the effect of the Coronavirus pandemic most specially at the part of US who is still leading its way to the top of having the most number of cases in the span of months that the pandemic is on this year 2020. Such political issues and egos of both leaders from US and China must be set aside for a while and better focus on the welfare of its people rather than raising a war that can just cost lives and would be a nonsense fight because this pandemic is already causing death due to health related threat.

Also, I do not think hacking of Bitcoin will be involved on the tension between those two big countries for what are they are fighting is on a political matter and also health related due to issues that Pres. Trump is throwing against China regarding the reason of starting this pandemic for it is said that the virus originated in Wuhan, China which is the ground zero of the virus. With that, there is no concrete reason to involve Bitcoin then.

Bitcoins cannot be hacked, but they can attack 51%.
China has 81% of the pool of miners mining bitcoin, which also means there is a high chance that China will strike 51% if the miner's team up to carry out the attack. I think they won't do it, they will push the bitcoin price higher because they mine the most which also means they hold the most bitcoin.
