Abstract

同时捕捉BTC表现的提升和ETH的大幅波动。

原文作者:BitMEX

gm,欢迎回到我们的每周期权 alpha 系列。上周,我们讨论了与 2020-2021 年牛市相比,比特币期权可能被低估的情况。我们提到交易者可以通过设置跨式策略来捕捉潜在的波动率上升。

在本文中,我们将向您介绍一种巧妙的方法,可以在不使用期权的情况下利用 ETH 价格的大幅波动 —— 这种方法允许交易者同时捕捉 BTC 表现的提升和 ETH 的大幅波动。这个策略在某些方面比设置跨式策略更有效!

让我们深入了解一下。

BitMEX 的 Quanto 永续合约:独特的衍生品

Quanto 永续合约,如 BitMEX 上的 ETHUSD quanto 永续合约,为加密市场的交易者提供了一个独特的机会。这些合约以 BTC 结算,这意味着盈亏是以比特币而不是 USDT 或 ETH 支付的。

它如何与期权相似?

Quanto 的独特结算机制,结合 BTC 和 ETH 之间的强相关性历史,为交易引入了“convexity 凸性元素”。与期权类似,这种 convexity 允许交易者可能从任何方向的显著价格变动中获利。通过战略性地结合两个永续合约头寸,交易者可以获得凸性敞口,潜在地从大幅上涨或下跌中受益。这一特征使 quanto 永续合约区别于传统的 delta-1 永续合约,后者通常提供线性回报。使用 quanto 永续合约,交易者可以创建在波动市场中可能盈利的投资组合,不论价格变动的方向如何,只要变动足够大以克服成本。

为了说明这种交易的独特收益结构,让我们来看一个模拟:

  • 开立 1 ETH 的 quanto 合约头寸,并结合 1 ETH 的 USDT 结算 ETH 永续合约空头:

  • 如果 ETH 价格保持相对稳定,整体盈亏趋于低位

  • 但如果 ETH 在任何方向经历显著的价格变动,获得可观利润的潜力就会大大增加

请注意,模拟是在 ETH 交易价格约为 2500 美元时创建的,ETH/BTC 相关性为 0.6 

这个交易策略给交易者带来了一个不错的机会:

  • 可以同时捕捉市场上涨和下跌的行情,不管价格往哪个方向大幅波动都有可能赚钱

  • 特别适合在市场不确定性高或预期波动加剧的时候使用

不过,这个策略也有个主要的风险要注意:

交易风险

  • 最大的挑战来自资金费率

  • 通常情况下,ETHUSDT 空头每个周期能拿到大约 0.01% 的资金费

  • 但是 ETHUSD quanto 这边要付出的资金费往往超过 0.01% (写这篇文章时是 0.05% )

  • 这两个费率之间的差额就是持仓的"成本"

考虑到这个成本结构,入场时机就变得特别关键了:

  • 最理想的入场时机是在你预计市场即将出现大动作之前

  • 记住,只要行情大幅波动,不管是涨是跌都有机会赚钱

如果能掌握好这些要点,交易者就可以充分利用 quanto 合约的特性,在控制风险的同时从市场波动中获利。

如何操作

具体交易步骤:

  • 在 BitMEX 平台上做多 1 个 ETH 的 ETHUSD quanto 永续合约

  • 同时在 BitMEX 上做空 1 个 ETH 的 ETHUSDT 永续合约

不同情况下的表现:

1. 如果 ETH/USD 上涨 10% : 

  • Quanto 多头:以比特币计价赚 10% 

  • USDT 永续空头:以 USDT 计价亏 10% 

  • 最终结果:如果 BTC/USDT 也上涨的话就能赚钱,因为比特币计价的收益会超过 USDT 的亏损

2. 如果 ETH/USD 下跌 10% : 

  • Quanto 多头:以比特币计价亏 10% 

  • USDT 永续空头:以 USDT 计价赚 10% 

  • 最终结果:如果 BTC/USDT 也下跌的话就能赚钱,因为 USDT 的收益会超过比特币计价的亏损

主要风险:

1. 资金费率开支: ETHUSD quanto 的资金费率通常比 ETHUSDT 高。长期持仓的话,一年的成本可能超过 20% 。

2. ETH/BTC 相关性: ETH 对 BTC 的比值变化会大大影响盈利情况。BTC 价格走强对这个策略有利,反之亦然。

总结

用 BitMEX 的 quanto 和 USDT 永续合约来操作,比直接玩期权更省钱。如果你觉得短期内 ETH 可能会剧烈波动,但又不确定会涨还是会跌,这个策略就特别合适。

Zuckerberg Begins Betting on Prediction Markets, While Asian Countries Still View Them as Gambling

Mark Zuckerberg is backing prediction markets, with Meta developing its own app "Arena," signaling major tech validation. This industry now sees over $14 billion in monthly volume. These markets function as binary contracts (payout $1 if an event occurs, $0 if not), with trading prices reflecting real-time event probabilities. Results are settled by oracles. Prediction markets originated from informal political betting and academic experiments like the Iowa Electronic Markets. Their core mechanism relies on "skin in the game"—participants risk their own money, making aggregated information more reliable than polls or expert opinions. They have proven accurate in forecasting areas like monetary policy, elections, and market events. While Western markets are integrating them into regulated financial systems, many Asian jurisdictions still classify them as gambling, leading to regulatory divergence. This stance creates three major issues for Asia: regulatory arbitrage and capital outflow, loss of informational sovereignty as valuable social data accumulates offshore, and a lack of user protection within a formal framework. The article argues that Asia's focus should shift from blocking these markets to responsibly harnessing the data they generate within a regulated system. The current avoidance of discussion cedes leadership and advantages to foreign entities.

DIGITAL GOLD ($BITCOIN): A Comprehensive Analysis Introduction to DIGITAL GOLD ($BITCOIN) DIGITAL GOLD ($BITCOIN) is a blockchain-based project operating on the Solana network, which aims to combine the characteristics of traditional precious metals with the innovation of decentralized technologies. While it shares a name with Bitcoin, often referred to as “digital gold” due to its perception as a store of value, DIGITAL GOLD is a separate token designed to create a unique ecosystem within the Web3 landscape. Its goal is to position itself as a viable alternative digital asset, although specifics regarding its applications and functionalities are still developing. What is DIGITAL GOLD ($BITCOIN)? DIGITAL GOLD ($BITCOIN) is a cryptocurrency token explicitly designed for use on the Solana blockchain. In contrast to Bitcoin, which provides a widely recognized value storage role, this token appears to focus on broader applications and characteristics. Notable aspects include: Blockchain Infrastructure: The token is built on the Solana blockchain, known for its capacity to handle high-speed and low-cost transactions. Supply Dynamics: DIGITAL GOLD has a maximum supply capped at 100 quadrillion tokens (100P $BITCOIN), although details regarding its circulating supply are currently undisclosed. Utility: While precise functionalities are not explicitly outlined, there are indications that the token could be utilized for various applications, potentially involving decentralized applications (dApps) or asset tokenization strategies. Who is the Creator of DIGITAL GOLD ($BITCOIN)? At present, the identity of the creators and development team behind DIGITAL GOLD ($BITCOIN) remains unknown. This situation is typical among many innovative projects within the blockchain space, particularly those aligning with decentralized finance and meme coin phenomena. While such anonymity may foster a community-driven culture, it intensifies concerns about governance and accountability. Who are the Investors of DIGITAL GOLD ($BITCOIN)? The available information indicates that DIGITAL GOLD ($BITCOIN) does not have any known institutional backers or prominent venture capital investments. The project seems to operate on a peer-to-peer model focused on community support and adoption rather than traditional funding routes. Its activity and liquidity are primarily situated on decentralized exchanges (DEXs), such as PumpSwap, rather than established centralized trading platforms, further highlighting its grassroots approach. How DIGITAL GOLD ($BITCOIN) Works The operational mechanics of DIGITAL GOLD ($BITCOIN) can be elaborated on based on its blockchain design and network attributes: Consensus Mechanism: By leveraging Solana’s unique proof-of-history (PoH) combined with a proof-of-stake (PoS) model, the project ensures efficient transaction validation contributing to the network's high performance. Tokenomics: While specific deflationary mechanisms have not been extensively detailed, the vast maximum token supply implies that it may cater to microtransactions or niche use cases that are still to be defined. Interoperability: There exists the potential for integration with Solana’s broader ecosystem, including various decentralized finance (DeFi) platforms. However, the details regarding specific integrations remain unspecified. Timeline of Key Events Here is a timeline that highlights significant milestones concerning DIGITAL GOLD ($BITCOIN): 2023: The initial deployment of the token occurs on the Solana blockchain, marked by its contract address. 2024: DIGITAL GOLD gains visibility as it becomes available for trading on decentralized exchanges like PumpSwap, allowing users to trade it against SOL. 2025: The project witnesses sporadic trading activity and potential interest in community-led engagements, although no noteworthy partnerships or technical advancements have been documented as of yet. Critical Analysis Strengths Scalability: The underlying Solana infrastructure supports high transaction volumes, which could enhance the utility of $BITCOIN in various transaction scenarios. Accessibility: The potential low trading price per token could attract retail investors, facilitating wider participation due to fractional ownership opportunities. Risks Lack of Transparency: The absence of publicly known backers, developers, or an audit process may yield skepticism regarding the project's sustainability and trustworthiness. Market Volatility: The trading activity is heavily reliant on speculative behavior, which can result in significant price volatility and uncertainty for investors. Conclusion DIGITAL GOLD ($BITCOIN) emerges as an intriguing yet ambiguous project within the rapidly evolving Solana ecosystem. While it attempts to leverage the “digital gold” narrative, its departure from Bitcoin's established role as a store of value underscores the need for a clearer differentiation of its intended utility and governance structure. Future acceptance and adoption will likely depend on addressing the current opacity and defining its operational and economic strategies more explicitly. Note: This report encompasses synthesised information available as of October 2023, and developments may have transpired beyond the research period.
