Are we excited yet?

Actual gold will go up. Magical "digital gold" won't. However what often happens is that it spikes as people pour in, and then hits a slump later on before they get out.

There would likely just be a rush to safe-havens.

Actually the link could not be deleted. The link is in the blockchain - no? Immutable yadda yadda yadda. Where it points to could be gone though. Regardless, if that happens, then what you are left with just a cryptographic hash in a digital ledger. Which is what you have with a cryptocurrency

People can do what they want. It is their money. Money always flows to safe havens in times of crisis. That's just an empirical fact. Cryptocurrency is a 100% speculative asset. If you want to have your money in an 100% speculative asset at a time of crisis, that is your choice. If you want to take money out of other assets and put it into that speculative and volatile asset at that time, again that is your choice.

Your bitcoin may go up, or it may go down. I would have zero confidence in a prediction that a war would drive up its price. I would have a lot of confidence in a prediction that a war would have money flowing into gold (there would probably be a slump afterwards, but that is not what is being talked about here)

What is your argument against it being called a speculative asset? Because that is what it is. The fact that it tends to increase in price over time is not a refutation of it being a speculative asset. People can invest in speculative assets if they want, and can do very well out of it. Or they can lose their shirts on them. There is nothing wrong, per se, with having a punt on them if you want.

Wrong.

Sovereign bonds. You might have heard about a thing called negative interest rates? The short end of the yield curve has been negative for years for many currencies. You can also buy them on the secondary market as well as buying them at issuance. And, in certain circumstances, you will pay more for them than what they will redeem at (even for ZCs). They aren't hoping they lose money - they know they will lose money (Unless of course they sell them on on the secondary market .... but eventually money is lost)!

Every day is a school day.

For the second part you said:

Again, not always true. For example, you might buy an asset for your business which you know will depreciate but you can hope that it will help you to make money in other ways. Like a van.

Or you might buy an asset to use it - e.g. to live in a house - rather than for speculative purposes

That's fine. Should a war break out you are free to liquidate everything and throw it into crypto assets should you so wish.

What are you using it for yourself btw? Given it's strengthening position in that regard.

Just a heads up for you. The Fed is likely to raise rates over there very soon. It may even though so on an emergency basis before its next scheduled meeting. That may or may not be already factored into the current level of your bitcoin.

"The Fed is likely to raise raise rates over there"

"there" being where the Fed is - given you appear confused.
