I believe that in bad times, which will inevitably come in the form of a crisis, it is bad to hold assets in bitcoin. And the crisis will come because there is a conflict in the world and supply chains are collapsing, as well as economic ties that have been worked out for years. Many industries receive less raw materials and technologies due to the expansion of exports and imports from abroad. The fact is that it so happened that in bad times people bought gold or goods like equipment, but not cryptocurrencies. Bitcoins are bought only when everything in the world is good.
No one knows the ideal safe-haven asset for future crises. People here believe that Bitcoin has become a safer asset than anything else and has the potential for significant price increases. It's possible that people out there are more inclined to secure their assets in other forms.
However, on the other hand, I think that when a crisis occurs, there will be significant inflation, and as long as those who understand how to store Bitcoin remain scarce, the best refuge for financial security will be gold. FIAT currency will undoubtedly be abandoned, and I believe that the price of gold, due to its worldwide demand, will exceed that of Bitcoin. Correct me if I'm wrong.
I agree with the second paragraph of your post. This behavior of people has already been observed more than once. Perhaps this is due to the fact that gold is material, it can be touched, stored in a safe, and no one on the Internet is able to take it away from you. Or take it away the way banks take away people's money stored in their accounts. Probably such thinking originates from ancient times. I'm not saying that you need to transfer all assets only to gold.
No one has canceled risk diversification. Therefore, it is only necessary to redistribute the shares in the portfolio towards gold, and reducing the share of cryptocurrencies. And then, when the crisis weakens, determine the advantageous moment of entering the market and exchange your fiat and stablecoins for cryptocurrencies.
