欢迎来到我们的每周期权 Alpha 系列!

比特币刚刚大幅下跌,跌幅达到 10% 。你的投资组合出现亏损,你可能会想:“接下来该怎么办?是恐慌、加仓,还是聪明地操作?”

期权策略可以帮助管理风险、利用可能的反弹或产生收入。以下是五种针对抛售后场景的有效策略,附带示例、盈亏分析和情境指导。

(本文撰写时, 2025 年 2 月 26 日,香港时间 13: 06 ,BTC 价格为 88, 584 美元。)

1. 如果你担心比特币在三月还会继续下跌…… 做法:购买保护性看跌期权(你的保险策略)

假设你持有的比特币价格为 89, 000 美元,但你因比特币可能在三月跌至 75, 000 美元而难以入睡。别坐等——为自己做个对冲!买入一个看跌期权来锁定一个底价。

示例:

● 比特币价格: 89, 000 美元

● 买入 85, 000 美元看跌期权(到期日: 3 月 28 日),期权费为 3, 000 美元。

为什么有效: 

如果比特币暴跌至 75, 000 美元:

● 你的看跌期权支付 10, 000 美元(85, 000 美元 - 75, 000 美元)。

● 扣除 3, 000 美元的期权费后,你净赚 7, 000 美元。这笔钱可以用来以极低的价格购买更多比特币,或者弥补你的投资组合亏损。

如果比特币上涨至 100, 000 美元:

● 你只损失 3, 000 美元的期权费,但你的现货持仓飙升。为了心理安慰,这个小价格是值得的。

最坏的情况是:如果比特币维持在 89, 000 美元左右或仅小幅上涨,那么看跌期权将失效,损失 3, 000 美元的期权费,但你的比特币持仓可能已增值。为了保护和安心,这笔费用是值得支付的。

总结: 这是为那些偏向多头但又担心市场进一步下跌的投资者设计的。你不想卖掉比特币,但你需要下行保护。把它当作支付保险费,确保能安稳入睡。

2. 如果你认为比特币会在接下来几周维持平稳…… 做法:卖出覆盖性看涨期权(将无聊变现)

假设你被困在 89, 000 美元的比特币上,但不指望短期内出现大行情。那不如在等待的同时让市场支付你!卖出看涨期权来赚取期权费。

示例:

● 比特币价格: 89, 000 美元

● 卖出 95, 000 美元的看涨期权(到期日: 3 月 28 日),期权费为 2, 600 美元。

为什么有效: 

如果比特币维持在 89, 000 美元:

● 你赚取 2, 600 美元。这是 30 天内无所事事就获得的 3% 的收益。

如果比特币上涨至 100, 000 美元:

● 你仍然盈利:

○ 在 95, 000 美元卖出(获利 6, 000 美元)

○ 保留 2, 600 美元期权费

○ 总利润为+ 8, 600 美元。

最坏的情况是:错过 95, 000 美元以上的涨幅。但是说实话,经历过一次抛售后,你真的指望在 30 天内有 20% 的涨幅吗?

总结: 这是“我愿意收点免费的钱”策略。如果你对比特币略微看涨,或只是想在持仓时减少成本,这是一个完美的选择。

3. 如果你认为比特币会有反弹(但不会太疯狂)…… 做法:牛市看涨价差(廉价参与反弹)

你认为比特币已经被过度抛售,预计会反弹 10-20% ,但又不想冒太大的风险去买看涨期权。那么,牛市看涨价差就是一个预算友好的选择。

示例:

● 买入 85, 000 美元的看涨期权,价格为 7, 200 美元(到期日: 3 月 28 日)。

● 卖出 90, 000 美元的看涨期权,价格为 4, 000 美元(到期日: 3 月 28 日)。

● 净成本: 3, 200 美元。

为什么有效: 

如果比特币涨到 90, 000 美元:

● 最大利润为 1, 800 美元(5, 000 美元价差 - 3, 200 美元成本)。这相当于 50% 以上的回报!

如果比特币保持在 85, 000 美元以下:

● 你损失 3, 200 美元。但这比单独买入 7, 200 美元的裸期权要小得多。

盈亏平衡点为 88, 200 美元——上涨 4.8% 。

总结: 这是为谨慎的乐观者设计的策略。你不指望比特币大幅上涨,只是预期会有小幅反弹。风险较小,睡得更好。

4. 如果你对比特币的走势完全不确定(但预期会有大波动)…… 做法:长时间跨式期权(从混乱中获利)

在经历了一次抛售后,比特币可能会剧烈反弹或继续下跌。如果你准备好赌一把波动性,那么购买同时的看涨和看跌期权就是一个选择。

示例:

● 比特币价格: 89, 000 美元

● 买入 88, 000 美元看涨期权和 88, 000 美元看跌期权(到期日: 3 月 28 日),总费用为 9, 000 美元。

为什么有效: 

如果比特币爆涨至 100, 000 美元:

● 看涨期权盈利 11, 000 美元,扣除 9, 000 美元期权费后净赚 2, 000 美元。

如果比特币跌至 70, 000 美元:

● 看跌期权盈利 19, 000 美元,扣除 9, 000 美元期权费后净赚 10, 000 美元。

盈亏平衡点:比特币需要波动 10% 以上。这在抛售后是非常可能的。

总结: 这是“我不关心方向,只关心波动”的策略。风险大吗?是的。回报大吗?绝对大——如果你猜对了。

5. 如果你认为此次抛售被过度反应…… 做法:卖出看跌价差(押注稳定性)

你认为恐慌导致了此次抛售,而比特币将稳定下来或反弹。卖出看跌价差,赚取期权费,并明确风险。

示例:

● 卖出 85, 000 美元看跌期权,期权费为 2, 500 美元(到期日: 3 月 28 日)。

● 买入 80, 000 美元看跌期权,期权费为 1, 500 美元(到期日: 3 月 28 日)。

● 净收入: 1, 000 美元。

为什么有效: 

如果比特币维持在 85, 000 美元以上:

● 你保留 1, 000 美元的期权费。这是 100% 的收益。

如果比特币跌至 80, 000 美元:

● 你损失 5, 000 美元(85, 000 美元 - 80, 000 美元),但你保留了 1, 000 美元的期权费,因此最大损失为 4, 000 美元。

总结: 

这是“聪明的逆向投资者”策略。你通过押注恐慌只是暂时的来获得期权费。只要准备好现金,以防被迫以 85, 000 美元的价格买入比特币。

最终总结:

经历抛售后,情绪高涨,但聪明的交易者能够将不确定性转化为机会。关键是评估你的风险承受能力、市场展望和时间框架,然后选择合适的期权策略。以下是思考的方式:

● 如果你担心再次下跌,买入保护性看跌期权。

● 如果你认为比特币将横盘整理,卖出覆盖性看涨期权。

● 如果你预期反弹,选择牛市看涨价差。

● 如果你预期大波动,选择长时间跨式期权。

● 如果你认为市场反应过度,选择卖出看跌价差。

没有任何策略是万无一失的,所以始终管理好风险和仓位。若不确定,从小额开始,做好对冲,并让市场来验证你的判断。

Reviewing 8 'Cash Cow' Projects in the Bear Market: The Leader Repurchased $283 Million Worth This Year

This article highlights eight cryptocurrency projects that have demonstrated strong cash-generating capabilities and implemented significant token buyback programs during the bear market of 2026. These projects, dubbed "cash cows," are repurchasing their own tokens, often reducing supply. According to data from Tokenomist, the projects with notable buyback activity from January 1st to June 30th are: Meteora (MET), Pump.fun (PUMP), GMX, Rollbit (RLB), Metaplex (MPLX), Hyperliquid (HYPE), Lighter (LIT), and Aave. Notably, MET's buybacks equaled 71% of its January token supply, while HYPE executed the largest buyback by value at $283 million. Key project summaries include: - **Hyperliquid (HYPE):** The leader by dollar value, its perpetual DEX protocol has repurchased and burned 44 million HYPE tokens (approx. 4.4% of supply) using a significant portion of trading fees, with total buybacks exceeding $1.1 billion since March 2025. - **Meteora (MET):** Its buyback of 336.2 million MET tokens had the greatest proportional impact on its circulating supply, equivalent to 71% of its supply at the start of the year. - **Pump.fun (PUMP):** The popular memecoin launchpad has cumulatively bought back over $400 million worth of PUMP since July 2025, using 50% of net revenue for buybacks and burns since April. - **Aave (AAVE):** Despite facing a major security incident earlier in the year, the lending protocol has continued its buyback program, repurchasing over 200,000 AAVE tokens. Its team is designing a new automated buyback mechanism. - **GMX, Lighter (LIT), Rollbit (RLB), and Metaplex (MPLX)** also have active buyback mechanisms funded by protocol fees or revenues. The article concludes that while token buybacks and burns do not guarantee price appreciation—as market conditions, news, and other factors play a role—these projects stand out for their ability to generate consistent cash flow in a challenging market environment.

What is $BITCOIN

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.
