This is true for highly liquid assets with huge capitalization such as oil, real estate, stocks, etc. It seems to me that niche/low-cap/unique markets react differently. Goods from these markets were initially bought for a long time, and most of the investors in these goods initially assume that the period before its sale may be 1-2 (or more) economic cycles. I have not heard that someone "urgently" sold a unique painting just to get into the cache (this happens in bankruptcies, but this is a different case).
Bankruptcies happen for the exact same reason. It's only a matter when the assets are liquidated.
In broad strokes, these assets act exactly the same. This boils down to economic rationality. It doesn't matter if you invested in fine art or real estate. When the economy crashes and your business fails or you lose your job, you may need to liquidate assets to pay your mortgage or rent, bills, etc. This is the part of the underlying drive towards cash during liquidity crises.
This idea that people who invest in stocks or real estate need cash, but people who invest in low-cap or niche markets don'tdoesn't really pan out for me.
In a sense, you are right, but still, I believe that the bitcoin market is very far from a rational market due to low capitalization, the presence of large players (whales), etc. Obviously, this is far from a "theoretical" rational market where we must always see the effective / fair price of an asset.
So...
And yet Bitcoin crashed much harder than stocks or real estate this past March. Makes you wonder......
yee, that time everything went like this (by the way, the market recovered faster than the stock market), but maybe next time everything will turn out differently.
