The ultimate question in the crypto world: How should we view the security of digital assets?

Suppose the mathematical foundation becomes abnormal—no matter how absurd—the possibility of hash collisions arises, and private keys are no longer secret. Only then will you realize that DeFi and cryptocurrencies are fundamentally built on mathematics and electricity. They are ingeniously designed and operate efficiently, but they also have physical vulnerabilities.

This extreme assumption actually reminds us of one thing: what is the ultimate logic of asset allocation?

The answer is simple—don't digitize all your wealth.

Land, gold, food, water. These are native assets of the physical world; they do not rely on any algorithms or networks. In comparison, digital assets are like a castle built in the cloud.

A more pragmatic approach is: use DeFi mechanisms to earn yields, regularly withdraw profits, and gradually convert them into risk-resistant physical assets. This is not to deny the crypto world but to acknowledge its true value—it is an efficient tool for wealth appreciation, not the ultimate destination of wealth.

In other words, DeFi is a means; life itself is the purpose. When all virtual systems go offline, only what is in your hands is real.
