Recently, the market has been quite volatile. Bitcoin repeatedly tests the $80,000 level, with the Bank of Japan raising interest rates and US CPI data bombarding the headlines one after another. The derivatives market is daily playing out a battle between bulls and bears. But interestingly, the more such market conditions occur, the more people start to seriously consider a question: how to keep principal alive until the next bull run?

The answer is emerging from a type of asset—decentralized USD (USDD). Its appeal doesn't lie in how many times it can increase, but rather in the fact that it "does not fall."

The mechanism is quite straightforward. Through an on-chain verifiable over-collateralization model, decentralized USD aims to anchor the dollar's value on the blockchain. In other words, when your Bitcoin holdings are flying high with news headlines, allocating a portion to decentralized stablecoins serves as a "ballast" for your portfolio. When SOL crashes 30%, you won't panic; when the market fear index hits bottom, you still hold a relatively stable asset.

More importantly, this isn't just about holding assets passively and waiting for depreciation. In DeFi ecosystems built on efficient public chains like Tron, decentralized stablecoins can generate yields through staking, liquidity mining, and other methods. This way, you protect your principal while also allowing your funds to continue earning in a risk-averse state. For crypto investors, this solves a longstanding problem: how to preserve capital in a bear market without letting your money sit idle.

In fact, this reflects a more mature investment mindset. Forget about stories of overnight riches; true winners focus on asset allocation and risk management to navigate market uncertainties. Giving up the obsession with extreme returns in exchange for protection against extreme risks—before the next black swan event occurs, such on-chain treasuries are the lifelines that can save your skin.
