Well, gold has never been speculative, it has been deliberately made such an asset for several decades in a row by speculators in London. They told everyone that it was the same product as, for example, coal, even worse! Because it has no uses other than jewelry... But gold has never been a commodity. Gold is money in its perfect form. Now everything is back to normal.
But with bitcoin, not everything is as good as with gold. Because Bitcoin is subject to control. First of all, the price of bitcoin can be controlled by large holders. The network itself is completely controlled by the miners. That is, it is enough to control the miners to control the network. Most of the mining facilities are located in the United States, where the government will have no difficulty controlling anything, including the miners too.
Therefore, the largest countries consider bitcoin only as a situational tool that is convenient for calculations at the moment, but not as a currency of the future or an investment. However, I think that bitcoin, nevertheless, will be widely used by individuals when capital is fleeing from treasuries and other assets, because there are very few alternatives.
By declaring a trade war against China, the American government has completely changed all the rules of the game in the geopolitical space.
As a result, the world will most likely never be the same again. China has a lot of American treasury bonds. At the same time, they cannot sell them at once (since it is simply impossible to find buyers for such a volume of bonds). At the same time, the Communist Party of China no longer considers American treasury bonds as a reliable asset. They would be happy to get rid of this asset completely (but they cannot).
In these conditions, Bitcoin seems to be a very good alternative to American stocks and American treasury bonds. I do not quite agree with the thesis that Bitcoin is controlled by Americans (Bitcoin is a fairly decentralized asset, its miners and owners are located in different parts of the globe).
At the same time, Bitcoin has a significant advantage over gold - gold is very difficult to transport across borders, gold is not well suited for cross-border transactions, gold is easier to counterfeit than Bitcoin.
