抵押品和闪电贷款：加密货币借贷的关键要素

尽管加密贷款很普遍，但散户投资者通常需要抵押品才能获得贷款。唯一的例外是闪贷，它涉及在同一区块链交易中短期借款和返还资金，需要专业知识。然而，企业可以通过在 Goldfinch 等平台上提供链下资产作为抵押品来获得无需加密抵押品的加密贷款。大多数加密货币贷款都需要超额抵押，允许贷方使用超额抵押品作为担保来绕过信用检查。抵押不足的贷款存在，但风险和利率较高，需要谨慎行事。

Cryptocurrency Loans: Understanding the Role of Collateral and Flash Loans

加密货币贷款：了解抵押品和闪电贷款的作用

In the realm of decentralized finance (DeFi), crypto loans have emerged as a key mechanism for leveraging digital assets to access liquidity. However, unlike traditional banking, crypto loans typically require borrowers to provide collateral to mitigate potential losses for lenders. This requirement stems from the innate volatility and unpredictable nature of cryptocurrency markets.

在去中心化金融（DeFi）领域，加密货币贷款已成为利用数字资产获取流动性的关键机制。然而，与传统银行业务不同，加密货币贷款通常要求借款人提供抵押品，以减轻贷方的潜在损失。这一要求源于加密货币市场固有的波动性和不可预测性。

Why Collateral is Essential in Crypto Loans

为什么抵押品在加密货币贷款中至关重要

The requirement for collateral in crypto loans serves a fundamental purpose: it acts as a safeguard against potential defaults. In the event that a borrower fails to repay their loan, the lender can seize and liquidate the collateral to recoup their initial investment. This risk-mitigation strategy allows lenders to provide loans without the need for extensive credit checks or background investigations.

加密贷款中对抵押品的要求有一个基本目的：它可以作为防止潜在违约的保障措施。如果借款人未能偿还贷款，贷款人可以扣押并清算抵押品以收回初始投资。这种风险缓解策略允许贷款人提供贷款，而无需进行广泛的信用检查或背景调查。

Overcollateralization: A Prevalent Practice

超额抵押：一种普遍的做法

In the crypto lending landscape, overcollateralization has become a prevalent practice. This involves providing collateral that exceeds the value of the loan amount. Overcollateralization serves two key functions:

在加密货币借贷领域，超额抵押已成为一种普遍做法。这涉及提供超过贷款金额的抵押品。超额抵押有两个关键功能：

1. Increased Loan Accessibility: It enhances the accessibility of loans for borrowers who may have difficulty meeting stringent credit requirements.
2. Reduced Lender Risk: By providing additional collateral, borrowers reduce the risk profile for lenders, allowing them to offer more favorable loan terms and interest rates.

Understanding Loan-to-Value (LTV) Ratio

提高贷款可及性：它提高了可能难以满足严格信贷要求的借款人获得贷款的可及性。降低贷款人风险：通过提供额外的抵押品，借款人降低了贷款人的风险状况，使他们能够提供更优惠的贷款条件和利率。了解贷款价值 (LTV) 比率

The Loan-to-Value (LTV) ratio is a critical concept in crypto lending. It measures the ratio between the value of the loan and the value of the collateral. Maintaining a healthy LTV ratio is essential to avoid the risk of liquidation. If the LTV ratio exceeds a predetermined threshold, the lender may issue a margin call, requiring the borrower to repay the loan or provide additional collateral to prevent liquidation.

贷款价值（LTV）比率是加密贷款中的一个关键概念。它衡量贷款价值与抵押品价值之间的比率。保持健康的 LTV 比率对于避免清算风险至关重要。如果LTV比率超过预定阈值，贷款人可能会发出追加保证金通知，要求借款人偿还贷款或提供额外的抵押品以防止清算。

Flash Loans: An Exception to the Collateral Rule

闪电贷款：抵押品规则的例外

Amidst the prevalent requirement for collateral in crypto loans, flash loans stand as a unique exception. Flash loans are short-term, uncollateralized loans that enable borrowers to access liquidity without providing any collateral. However, flash loans come with stringent technical requirements and are primarily utilized by experienced DeFi users.

在加密货币贷款对抵押品的普遍要求中，闪电贷是一个独特的例外。闪电贷款是短期无抵押贷款，使借款人无需提供任何抵押品即可获得流动性。然而，闪电贷具有严格的技术要求，主要由经验丰富的 DeFi 用户使用。

Undercollateralized Loans: A Risky Alternative

抵押不足的贷款：一个有风险的选择

Undercollateralized loans, where the value of the collateral is less than the loan amount, are also available in the crypto lending market. However, these loans often carry higher interest rates and pose a greater risk for lenders. As such, undercollateralized loans are generally advised against unless borrowers have a sound understanding of the risks involved.

抵押品不足的贷款，即抵押品的价值低于贷款金额，也可以在加密货币借贷市场上获得。然而，这些贷款往往利率较高，给贷方带来更大的风险。因此，除非借款人充分了解所涉及的风险，否则通常不建议提供抵押不足的贷款。

The Risk of Unsecured Lending

无担保贷款的风险

The recent market turmoil in the cryptocurrency industry has highlighted the inherent risks associated with unsecured crypto lending. The collapse of major crypto companies, such as Celsius and BlockFi, was partly attributed to the excessive engagement in unsecured lending practices.

最近加密货币行业的市场动荡凸显了与无担保加密货币借贷相关的固有风险。 Celest 和 BlockFi 等主要加密货币公司的倒闭，部分原因在于过度参与无担保借贷行为。

Conclusion

结论

For retail crypto investors seeking to borrow digital assets, collateral remains an essential requirement in the vast majority of cases. Overcollateralization, flash loans, and undercollateralized loans offer varying levels of risk and accessibility, each with its own set of considerations. Understanding these concepts is crucial for making informed decisions when navigating the complex landscape of crypto lending.

对于寻求借用数字资产的散户加密货币投资者来说，在绝大多数情况下，抵押品仍然是一项基本要求。超额抵押、闪电贷款和抵押不足贷款提供不同程度的风险和可及性，每种贷款都有自己的一套考虑因素。了解这些概念对于在复杂的加密借贷领域做出明智的决策至关重要。
