Better to use

with
• as separate items; they are not paragraphs but list items, but still each
• is a line. The rule says “段落 2–4 句，单段不超 6 句”. That might be interpreted as each paragraph must have 2-4 sentences. A list item might be considered a paragraph. But it’s okay if each list item has 2-4 sentences. We could have bullet points with sentences.

  Alternatively, we can embed a short paragraph listing the key takeaways as a list.

  We can also have each bullet as a short phrase, but the rule says each bullet should be a sentence? It’s ambiguous. We can do:

  Key Takeaways:
  – Use perpetual swaps to offset AI token price moves.
  – Monitor funding rates to avoid hidden costs.
  – Combine with spot holdings for balanced exposure.
  – Regularly rebalance hedge positions as market evolves.

  These are short statements, not sentences? They could be considered fragments. But maybe they satisfy.

  But the requirement is each paragraph 2-4 sentences. So we can make a paragraph with bullet points separated by
  or separate

  . But we must keep the bullet style.

  Better: use

  tags for each key takeaway, each containing a single sentence. That would be a paragraph with one sentence, which violates the 2-4 sentence rule. So we need at least 2 sentences per paragraph. So we can combine each bullet as two sentences? That would be too long.

  Maybe better to have a paragraph with multiple sentences summarizing key points, rather than bullet list. For example:

  Key Takeaways: Hedging AI token exposure with perpetuals reduces directional risk while keeping market exposure. Funding rates must be monitored to ensure hedge costs stay low. Combining perpetual positions with spot holdings creates a balanced portfolio. Rebalancing the hedge regularly adapts to market volatility.

  That’s four sentences in a paragraph, satisfying 2-4. That’s fine.

  – What is X: define hedging AI token portfolio with perpetuals. Provide explanation.

  – Why X matters: importance for portfolio management, risk reduction.

  – How X works: mechanisms, formula for hedge ratio, perpetual swap mechanics, funding rate, mark price, etc. Provide a structured breakdown: maybe a formula H = (V_target / V_current) * (1 / (1 + delta_F)). Or more precisely, the hedge ratio = (exposure to AI tokens) * (price correlation) / (contract size). Actually we can propose a simple hedge ratio formula: Hedge Ratio = (Value of AI Token Position * Beta) / (Perpetual Contract Notional). Or we can use “delta hedging”. The article can show that the target is to offset the delta of the AI token position using perpetual swaps. Provide formula: Number of Contracts = (Portfolio Delta) / (Contract Delta). Where Portfolio Delta = position size * delta of token, Contract Delta = notional per contract * price.

  But the user wants a structured mechanism or formula (模型/公式/流程图式拆解). We’ll provide a formula with explanation.

  – Used in practice: practical steps: opening a perpetual short position, determining size, monitoring funding, rebalancing.

  – Risks / Limitations: funding rate risk, counterparty risk, liquidity, model risk, slippage, correlation breakdown.

  – X vs Y: compare perpetual swaps vs futures, perpetual swaps vs options.

  – What to watch: funding rate trends, AI token regulatory news, market volatility, liquidity changes, funding of AI projects.

  – FAQ: 5-8 questions with

  headings, each answer paragraphs with 2-4 sentences.

  We must keep the entire article around 800 words. Let’s count approximate words. We’ll aim for roughly 13-14 paragraphs, each about 3 sentences, each about 15-20 words (so 45-60 words per paragraph). 14 paragraphs * 50 words = 700 words. Add some extra for headings and list items? That could be about 800. Let’s calculate.

  We’ll produce roughly:

  Intro (1 paragraph ~4 sentences) ~ 70 words.
  Key Takeaways (1 paragraph ~4 sentences) ~ 70 words.
  What is X (2 paragraphs ~3 sentences each) ~ 120 words.
  Why X matters (1 paragraph ~4 sentences) ~ 80 words.
  How X works (2 paragraphs: one with formula ~4 sentences, one describing steps ~4 sentences) ~ 140 words.
  Used in practice (1 paragraph ~4 sentences) ~ 80 words.
  Risks / Limitations (1 paragraph ~4 sentences) ~ 80 words.
  X vs Y (maybe 2 paragraphs each ~3-4 sentences) ~ 140 words.
  What to watch (1 paragraph ~4 sentences) ~ 80 words.
  FAQ (5 questions, each with 2-3 sentences) ~ 5*30 = 150 words.

  Total ~ 1010 words. That is a bit too many. We need to trim.

  We need about 800 words. Let’s aim for fewer paragraphs, shorter sentences. Perhaps combine some sections.

  Let’s restructure:

  – Title H1
  – Intro (1 paragraph)
  – Key Takeaways (1 paragraph)
  – What is X (1 paragraph)
  – Why X matters (1 paragraph)
  – How X works (maybe 2 paragraphs: one formula, one process)
  – Used in practice (1 paragraph)
  – Risks / Limitations (1 paragraph)
  – X vs Y (maybe 1 paragraph, but can be 2 if needed)
  – What to watch (1 paragraph)
  – FAQ (maybe 6 questions each 2 sentences => 12 sentences)

  Counting paragraphs: Title (1), Intro (1), Key Takeaways (1), What is X (1), Why X matters (1), How X works (2), Used in practice (1), Risks (1), X vs Y (1), What to watch (1), FAQ (maybe 6 paragraphs). That’s 14 paragraphs (excluding title). Each paragraph 3-4 sentences average 4 sentences. 14*4=56 sentences. Average 15 words per sentence => 840 words. That’s close to 800.

  Let’s target each paragraph around 3 sentences on average. 14*3=42 sentences * 15 = 630 words. That’s too low. Let’s aim for 4 sentences each (makes 56 sentences). 56 sentences * average 15 words = 840 words. We can trim a bit.

  Better to aim for 13 paragraphs * 4 sentences = 52 sentences. 52*15 = 780 words. That’s close.

  We’ll produce 13 sections (including title) but with headings for each section. Title H1 counts as heading but not paragraph.

  Now we need to embed citations. Use at least 3 citations.

  We need to follow the constraints:

  – No mini-outline.
  – No “In summary/To sum up”.
  – Avoid filler words like “Furthermore”.
  – Use active voice, present tense.
  – Provide utility: “Readers should…”

  – Use

  ,

  ,

  tags.

  – Provide at least 5 FAQ, up to 8.

  – Ensure each paragraph 2-4 sentences, max 6.

  Now I will draft.

  Title:

  How to Hedge an AI Token Portfolio With Perpetuals

  Intro:

  Introduction

  …

  Make sure first sentence is under 25 words, answer: “Hedge an AI token portfolio by using perpetual swaps to offset price risk and maintain market exposure.” That’s about 15 words.

  Now “Key Takeaways”. Provide bullet-like sentences, but ensure paragraph.

  We’ll write:

  Key Takeaways

  Perpetual swaps let you short AI tokens without selling the underlying assets. Funding rates determine the cost of holding a perpetual position. A calculated hedge ratio aligns the size of the perpetual contract with the token exposure. Rebalancing the hedge adapts to changing correlation and volatility.

  That’s 4 sentences.

  Now “What is X”. We need to define hedging AI token portfolio with perpetuals. Use citation maybe from Wikipedia about perpetual swap.

  We need to embed a link: Wikipedia.

  So:

  What Is Hedging an AI Token Portfolio With Perpetuals?

  Hedging an AI token portfolio with perpetuals involves opening a derivative position that moves opposite to the token’s price. A perpetual swap is a contract with no expiration date that tracks the underlying asset’s spot price through funding payments, according to Wikipedia. The goal is to neutralize downside risk while keeping the original token holdings for potential upside.

  That’s 3 sentences.

  Now “Why X matters”. Use citation from BIS maybe about crypto derivatives risk management.

  Why Hedging With Perpetuals Matters

  AI tokens exhibit high volatility, making sudden drawdowns common. Derivatives such as perpetuals provide a liquid, on‑chain method to offset those swings, as noted by the Bank for International Settlements. A proper hedge preserves portfolio value and reduces the need to liquidate assets during market spikes. This approach also allows traders to capture alpha while limiting exposure.

  4 sentences.

  Now “How X works”. Provide formula and process.

  We need a structured mechanism. Provide formula for hedge ratio: Number of Contracts = (Portfolio Delta) / (Contract Delta). Where Portfolio Delta = (Token Amount * Price) * Beta. Contract Delta for perpetual = Contract Notional / Mark Price. Or use delta of 1 because perpetual is linear. But we can present simplified approach.

  We also need to describe funding rate mechanism.

  Let’s produce two paragraphs under

  How It Works

  .

  Paragraph 1: The mechanics of perpetual swaps.

  Paragraph 2: The hedge ratio calculation.

  We must ensure each paragraph has 3-4 sentences.

  How It Works

  Perpetual swaps settle funding payments every eight hours, aligning the contract price with the spot market. If the contract trades above spot, longs pay shorts; if below, shorts pay longs, creating a built‑in price convergence mechanism, as explained by Investopedia. Traders can enter a short perpetual on a crypto exchange to profit when AI token prices fall.

  The hedge ratio determines how many perpetual contracts offset the token exposure. Use the formula: Contracts = (Token Value × β) / (Contract Notional), where β measures the token’s beta to the broader market and the contract notional equals the perpetual’s price times the contract size. Adjust the position when β changes or when funding costs shift.

  That’s 4 sentences in first paragraph, 3 in second.

  Now “Used in practice”. Provide steps.

  Used in Practice

  Start by quantifying the total dollar value of AI tokens in the portfolio. Calculate β using historical price data, then apply the hedge ratio to determine the required short perpetual size. Open the short perpetual on a platform that offers deep liquidity for the chosen AI token pair, such as Binance or Bybit. Monitor the funding rate daily; if it turns persistently negative, consider reducing the hedge to avoid accruing costs.

  That’s 4 sentences.

  Now “Risks / Limitations”. Must include limitations: funding rate risk, liquidity risk, counterparty risk, model risk, correlation breakdown.

  Risks and Limitations

  Funding rates can erode profits if the premium between perpetual and spot remains high for extended periods. Slippage on large orders may cause the hedge to be less precise, especially in low‑liquidity markets. Counterparty risk exists on centralized exchanges; on‑chain perpetuals mitigate this but introduce smart‑contract risk. Finally, β estimates rely on past data; sudden market regime changes can render the hedge ineffective.

  That’s 4 sentences.

  Now “X vs Y”. Compare perpetuals vs futures and perpetuals vs options.

  We need at least two concepts. We’ll have a single paragraph but include both comparisons.

  Perpetual Swaps vs. Futures and Options

  Unlike futures, perpetuals have no expiration date, removing the need to roll positions and incur roll‑over costs. Options provide a known maximum loss but demand upfront premium payments, whereas perpetuals
