When the economy is doing well, people pursue antiques, artworks, and various luxury goods; once economic downward pressure appears, these items immediately become "luxuries." Products that deviate from basic needs, such as Porsche, private coaching courses, and high-end beauty treatments, are the first to be cut. People will reevaluate every expense—rent, food, medical care—these essentials related to survival become the priority. The switching of economic cycles is like a mirror, reflecting what are truly necessities. This rule applies to any asset class and may be worth considering for those holding crypto assets.
