#美联储回购协议计划 【How has the "long-term value preservation tool" in the Bitcoin ecosystem evolved?】

Bitcoin defines the value storage position of digital assets, but holders face a real problem: how to protect the core asset while also hedging against depreciation risk in the long term?

Some protocols are now attempting an idea - combining the anchoring mechanism of stablecoins with the interest-generating capability of DeFi to create a tool for Bitcoin holders that offers "automatic value preservation + slow appreciation."

How do these types of solutions typically operate?

🔸 **Principal Safety**: Ensuring redemption capability through excessive on-chain collateral (usually over 130%), somewhat similar to the reserve system of traditional banks, but completely transparent and verifiable.

🔸 **Price Stability**: Through an algorithmic mechanism precisely pegged to 1 USD, you can redeem at any time with confidence, ensuring your purchasing power is certain, without worrying about the noise of price fluctuations.

🔸 **Deep integration with Layer2**: As part of the Bitcoin second layer ecosystem, these stablecoins can benefit from the expansion of the entire ecosystem rather than existing in isolation.

🔸 **Automatic Earnings**: The built-in yield mechanism of the protocol allows your assets to gradually appreciate while held, without any active operation; time is the return.

**So what does this mean for investors?**

Rather than frequently trading to chase short-term fluctuations, it's better to allocate a portion of assets to these stable and income-generating products—participating in ecological governance while also sharing in the long-term expansion dividends of Bitcoin Layer2.

Just a simple question: If you allocate Bitcoin ecological assets for yourself five years from now, what proportion do you think should be placed in these kinds of value-preserving and income-generating tools?
