We can expect that some tropical tax heaven country could do so.
Unless we will see state-issued stable coins being introduced.

What about goods shipped from China to other parts of the world?

This is a known fact, that during the collapse of the Soviet Union, there had been lost approximately 30-40 nuclear warheads in the size and shape of a suitcase. This is the official amount. Each warhead has its own "trace" - each reactor leaves unique characteristics of radioactive materials coming from it.

The question is - where are these actually being held? As a secret stash in some state? Forgotten in a bunker/ammo storage?

But to be honest the idea of fixed BTC size wallet would be something worthy of thinking about.

As well do not forget, that if you are somehow politically incorrect, often banks/payment providers may refuse to provide services to you. If you have in such case no access to hard cash (or cryptocurrency wallet), you simply cannot live a normal life, as you will not be able to pay even for own groceries.

Przy okazji warto zauważyć, że wydruk z drukarki laserowej jest trwalszy (nie blaknie) od wydruku z atramentu.

Niemniej jednak takiej pompki jak w wypadku LTC raczej nie ma co oczekiwać, wzrosty o 1000% to już chyba raczej jest pieśń przeszłości jak mówimy o BTC. Tutaj bardzo dużo zależy też od tego, jak mass media będą nakręcały sytuację.

Still, it would be much faster than international wire transfer from 1st to 3rd world country. And much cheaper after taking into consideration volatility of BTC!

The answer is simple - taxes and mafia.

The USA once banned alcohol. As a result, authorities lost part of their revenue, mafia became rich and powerful (ever heard about Las Vegas), and people had been drinking anyway - but without the supervision of the state and health standards, people had been dying because they bought poison instead of liquors (as eg. you cannot distinguish methanol from ethanol in taste or smell).

And remember to have everything recorded, because with all the higher levels of verification you will be asked for sources of funds/how did you get the crypto and where from. If you fail to do so, then your account could be even suspended, making such a challenge impossible to be finished!

War War III in a military way will not happen, as all the major countries which could try to start one between themselves (about the global domination) already have nuclear weapons. And since the Cold War, we see that the fear of MAD (Mutually Assured Destruction, inevitable wiping out population of involved countries, which will lead us to the new ice age because of the amount of radioactive dust in the atmosphere) is too strong for a real war to emerge unless we get 100% effective ways of making nuclear arsenals ineffective (like capacity of shooting down all the missiles). Best of what can be done are smaller, so-called proxy conflicts, where indirectly big players compete with each other using smaller countries/fractions in case of civil war to compete or fight each other.

And the Cold War ended because of the economy.

This is basically a crawling world war - a war where one country is winning, as companies from this country are major global players crushing their foreign competitors; establishing your currency as a dominant one and influencing culture in a way that people want to buy products developed or produced in your country. As well as imposing foreign tax tariffs weakening export from countries and economic sanctions are right now an equivalent of battles.

Authorities have a capacity of at least partially control and manage crypto by the law, which is already imposing on companies verification of the users (including checking your source of income in some cases) and managing anti money laundering. As well in some countries, you cannot buy legally some cryptos using fiat (unless it is otc cash transaction with individuals).
But in many cases approach "why to ban it if you can tax it" is starting to prevail.

This is because banks are obliged to check your transactions for "unusual/unreasonable" patterns. And they are legally allowed to freeze your account with all the funds on it, or as they had been doing in case of many crypto users and investors in past years - shut down your bank account or refuse to provide services to you.

It is pretty easy to seize fiat on your account. Or get a police/military raid your house looking for gold or banknotes. It had been happening for decades already.

With cryptocurrencies in quite many cases it is almost impossible to get your crypto seized. In the case of hardware wallets, you still have a chance to get access to its content if it is stolen. If you are smart enough, you can keep your cold wallets in plain sight and basically no one will notice it - even on family photos.

The only threat would be for you as an owner of a cryptocurrency to get tortured in order to give all the access to your wallet, including passwords etc.

Check payouts - if you lose a bet, you lose the whole amount, when you win, you never get it double. As well BO have already a very bad reputation as such, as in the past many of them had been manipulating rates or blocking a possibility of withdrawing profits.

In the past, with the gold standard, the ability of funding warfare was very limited, therefore the size of the forces (founded by state ruler) was limited.
This is why in feudalism monarchs had been summoning local feudal lords with their forces.

To be honest, this could happen even today - this time feudal lords could have been replaced with corporations - can you imagine a tank division funded by eg. McDonald's?

Też tak uważamy, ale ten człowiek z całą pewnością będzie starał się pompować swojego forka, co generalnie w ramach "satoshi vision" musi oznaczać w pewnym stopniu szkodzenie wizerunkowi BTC. Zaś takie zagrywki (+możliwa współpraca z wielorybem, który rzuciłby na rynek w jednej transakcji naprawdę dużą ilość BTC) nie są czymś, czego nie możnaby się spodziewać.

Not to forget, that if you buy real estate and it is going from a nice location to the bad neighbourhood (people, facilities, infrastructure) in 10 years (what is more than enough), then you may not find yourself very profitable (if at all). As well, if a financial crisis will take place, then you will have problems with not even selling the real estate, but even renting it.
Not to mention that in some cities in the world, in general, the price of real estate remains at a similar level or can go down.

Another thing is that investing in real estate requires knowledge or hiring some professional. With BTC even if you are not a professional, as a HODLer so far you were able to generate a good rate of profits, of course, if you did not buy at ATH just to sell it lower in panic.

Foil hat mode on

Co jeśli pompa ma służyć nabiciu kieszeni, przed jakimś niespodziewanym wydarzeniem, które ma wstrząsnąć kryptowalutami i dać możliwość zrobienia jeszcze większego przekrętu?
Jak krewni D.K. złożą oświadczenie, że wycofują pozew i w ich mniemaniu Craig potwierdził, że jest Satoshi, to przecież BSV poszybuje w kosmos. I jako taki może na przykład powiedzieć, żeby ludziska pozbyli się masowo BTC, bo obecnie Chiny tak na prawdę kontrolują BTC (co wyklucza się z wolnościowymi założeniami BTC), nie to co mining pool BSV.
Albo że jakkolwiek to brzmi, gdzieś w kodzie źródłowym BTC jest poważna luka, którą kazało mu np. CIA umieścić i nikt jej nie zauważył dotąd? Szczególnie, jeżeli się okaże, że autentycznie z tej listy, którą podał ma nad 1 portfelem kontrolę i przy tym pokazowo skorzysta chociaż raz z tego portfela? Przecież to potencjalnie mogłoby spowodować spadki BTC o kilkadziesiąt procent...

In many countries NGOs, charities or donating pieces of art is often a leglised form of money laundering.
