Before interstellar migration truly becomes a reality, traditional forces' asset control measures will pose many challenges to digital assets. Although Bitcoin is touted as unfreezeable, it faces a more covert risk—being labeled. Once certain Bitcoins are tagged, they could be locked when converted into stablecoins. In comparison, physical gold has obvious advantages. It can preserve and increase value, and also meet people's privacy needs—holding it discreetly if you don't want to show off, or wearing it as jewelry if you want to display—balancing privacy and vanity. The competition between digital assets and traditional assets is far more complex than it appears on the surface. Technical features are just one aspect; regulatory frameworks and asset attributes are the decisive factors.
