I don't think so, most of the countries are keeping or buying more gold. Only a few sells
Nice seeing another unbiased person who says it as it is, unlike people with Trump's character who would blatantly lie about the obvious. They should prove how this is real/impactful when Gold is still retaining almost all the trillions of dollars it has gained in the past 1 year. Talk is cheap, however, they should know that Gold is a national treasure that most countries, if not all, have tested for centuries and trusted. So they will now sell it to buy Bitcoin when no country has even actualised their talked-about strategic Bitcoin reserve? That's laughable!
No one is saying that any government should sell part of their gold to buy bitcoin because if that government is serious and understands that exponential growth in bitcoin value, they will gladly set up a bitcoin strategy reserve and buy with as little as 5% of the country's funds to save gaurd the value of their wealth in bitcoin that's a fast growing asset in value.
Even though you are correct that governments (and/or central banks) need not allocate a lot to bitcoin in order to potentially profit stupendously, there are folks asserting that governments and central banks should sell their gold to buy bitcoin. If we already know that gold is losing value relative to bitcoin, then there can be all kinds of ways to consider reallocation to bitcoin and largely divesting from gold, and we would not even need to agree upon those various ways since even governments/institutions who choose such path of reallocating to bitcoin and divesting from gold are not going to come to similar conclusions regarding how to do it, and some will profit more from their potentially being more aggressive in their reallocation from gold into bitcoin, no matter how they choose to do it. On a practical level, it hardly makes sense to proclaim that governments should hang onto their gold and just buy additional bitcoin with any new revenue.. that seems overly whimpy to me, even though for sure there are going to be plenty of governments/central banks that choose either overlywhimpy approaches or even choose to stay no coiners and/or low coiners, just like individuals are also making those kinds of choices to hang onto relic ideas and/or fail/refuse to recognize the value and/or power of bitcoin as a place to put time, energy and value.
Gold has been in existence before the birth of Jesus Christ so why wouldn't it gain fame and possess the kind of value it has now and gain more confidence of the people because it has proven to be an edge to inflation. However, bitcoin is just 16 years old but look at how massive it has grown in value due to the potential it has, to the point that it has been tested as a store of value over time.
You seem to be contradicting yourself with a desire to stick with a "why not both" proclamation, and sure gold is not going to die right away, but it does not mean that it is a good place to stay invested, perhaps beyond 10% of an investment portfolio (at most), whether we are talking about governments/central banks, institutions and/or individuals.
Do you know that currently the price of 1kg of gold = 1btc at when bitcoin price was $102k+. Bitcoin will create a new ATH in this circle and the price of 1btc >1kg of gold. Let's check this out, it means that in 10years time 1btc will be 5kg of gold. Have you seen the reality that in future which nobody knows when but due to the rate of adoption of bitcoin, bitcoin and gold will be of the same market cap. You need to see the vision just like the early investors in bitcoin saw the vision of how bitcoin price will be in six digits now.

Perhaps a better presentation is to show that bitcoin continues to catch up to gold's market cap.
https://tradingdifferent.com/dashboard/bitcoin-vs-goldBetween 2017 and 2020, bitcoin was largely bouncing around 0.5% to 2.5% of gold's market cap, yet from 2021 to now, bitcoin has been largely bouncing between 3% and 10% of gold's market cap, and there is no reason to conclude that the upward trend of bitcoin gaining more and more of gold's market cap is not going to continue... which surely we could have equal market caps and even bitcoin becoming 10x or more of gold's market cap within the next 6 months to even draging out to 10 to 15 years.
Surely it can be hard to know going forward how the change will continue to occur, including if it could take 50-200 years for bitcoin to reach 1,000x gold's market cap... yet we should still be able to recognize and appreciate the direction of the trend.
Retail buying gold and banks selling them to buy crypto.
Gold is useless for banks in the new financial system gold is not corruption free like btc or crypto there is no actual track of gold how much gold is minted and controlled so bankers don't need gold they need btc and crypto.
Retail buying gold so bankers selling gold and buying crypto.
The biggest secret is that banks buying crypto a lot not gold the gold is for retail buyers.
Even If gold have utility and use case then corporations want to buy gold for cheap off course they do that when gold crashing while btc and crypto will go up.
All this gold shilling what's going on is just for bankers to get rid of their gold and buy btc you see brics nations buying up gold so that gomex of western countries can use gold futures to manipulate gold price up without even buying gold with eur usd or gbp currency.
Gold now is biggest dump project on the silly retail traders with the help of india and china together with wall street and western bankers.
(G)OLD for me is in the old order of investment, for this current generation and in the of reality of today gold doesn't cut the short that much, the value to which cryptocurrency is growing across the world, the pace cannot be compared to gold, as cryptocurrency is on a higher frequency and adaptability amongst the young generation across the length and breadth of the Earth. People are used to gold and they've seen how far it has gone, people want something new and flexible and cryptocurrency has all the features investors are looking for. how acceptable is gold to the younger generation compared to cryptocurrency. So the banks know what they are doing and are investing wisely.
You are quite distracted if you believe that crypto currencies are offering anything of meaning as a competitor to gold. Perhaps if you replace your use of the term "cryptocurrencies" with "bitcoin", then you might be able to get yourself on a better track, to the extent that you understand the difference between bitcoin and crypto. Your choice to use the term crypto tends to show that you may well not really understand what bitcoin is.
