什麼是山寨幣？
重點洞察 Bitcoin 佔加密貨幣總市值的比例稱為 Bitcoin 主導率（Bitcoin Dominance），通常介於 40-65% 之間。當主導率下降時，資金正流入山寨幣；當主導率上升時，投資者正撤退至 Bitcoin 相對安全的懷抱。
Altcoin 是「替代幣」的縮寫——泛指所有非 Bitcoin 的加密貨幣。這個詞起源於 Bitcoin 早期，當時首批替代品（Litecoin、Namecoin）以修改後的 Bitcoin 程式碼推出。
如今，altcoins 已超過 20,000 種，涵蓋從 Ethereum 等主要平台到作為玩笑創建的 meme 代幣。絕大多數將以失敗告終，但最成功的 altcoins 已開創出全新的數位金融類別。
Bitcoin 占加密貨幣市場總市值的比例稱為 Bitcoin 主導地位，通常介於 40-65% 之間。當主導地位下降，代表資金正流入 altcoins；當其上升，則代表投資者正退守至 Bitcoin 的相對安全性。

山寨幣季節
Phase 1 — Bitcoin Leads
Bitcoin breaks out first as macro liquidity improves or a catalyst (e.g. the spot ETF approvals in January 2024) draws institutional flows. BTC dominance — Bitcoin's share of total crypto market cap, viewable on CoinGecko or TradingView — typically rises into the 55–65% range. Altcoins drift sideways or bleed against BTC even when their USD prices look flat.
Phase 2 — Large-Cap Rotation
Once BTC consolidates after a strong move, profits rotate into Ethereum and other top-10 assets. The ETH/BTC ratio turns up from its lows (it bottomed near 0.045 in mid-2024 after Dencun, versus the 0.08 level seen in late 2021), and BTC dominance starts to fall. Layer-1 majors like SOL, AVAX, and BNB usually move next.
Phase 3 — Alt Season
Capital flows down the risk curve into mid and small caps, meme coins, and narrative plays. The Blockchain Center 'Altcoin Season Index' crosses 75. Historically these phases have been short — the late-2017 and early-2021 alt seasons each ran roughly 8–12 weeks before peaking. Many tokens post 5–10x moves; many retrace 80%+ within months.
Phase 4 — Reversal
Risk appetite drops, BTC dominance surges, and altcoins fall harder than Bitcoin. In the 2022 bear market, BTC fell ~75% from its November 2021 high while many large-cap alts fell 85–95% and most small caps went to zero or near-zero. Liquidity evaporates first in the smallest tokens, making exits costly even before prices fully reset.
山寨幣風險
✓ Liquidity Risk
Outside the top ~30 tokens, order books on major exchanges are thin. A market sell of $1–5M can move a mid-cap 5–15% in a single trade, and during stress events (e.g. the FTX collapse in November 2022) spreads on smaller alts widened to 10%+ as market makers pulled quotes.
✓ Token Unlock / Dilution Risk
Most VC-backed altcoins launch with 10–20% of supply circulating and the rest vesting over 3–4 years. Cliff unlocks have repeatedly preceded sharp drawdowns: ARB's first team/investor unlock in March 2024 added ~1.1B tokens (~76% of then-circulating supply) and ARB fell over 50% in the following months; APT and SUI have shown similar patterns around monthly unlocks. Track schedules on TokenUnlocks, CryptoRank, or each project's docs before sizing a position.
✓ Regulatory Risk
The SEC named 60+ tokens as 'securities' in its 2023 cases against Binance and Coinbase, and exchanges have delisted assets in response (Bittrex US delisted ALGO, OMG, MATIC, and DASH in 2023). EU MiCA rules took full effect for crypto-asset service providers in December 2024 and impose stablecoin and disclosure requirements that smaller projects often fail to meet.
✓ Project / Rug Pull Risk
Anonymous teams, unaudited contracts, and concentrated token ownership are common in small caps. Chainalysis attributed roughly $4.6B of 2024 crypto crime proceeds to scams and rug pulls, with most exit scams happening on tokens under $50M market cap. Even audits aren't guarantees — Euler Finance was audited multiple times before its $197M exploit in March 2023.
✓ Technology / Competition Risk
Layer-1s that lead one cycle often lag the next. EOS peaked near $22 in 2018 and trades below $1 today; previous 'ETH killers' like Tezos and Cardano have lost significant developer mindshare to Solana and L2s like Base and Arbitrum since 2023. The Ethereum Pectra upgrade (2025) and ongoing L2 fragmentation continue to reshape which tokens capture activity.
✓ Correlation Risk
Altcoin/BTC 90-day correlations typically sit above 0.7 and rise toward 0.9 during sell-offs, so holding many alts is not effective diversification. In bear phases altcoins also exhibit a higher beta to BTC — historically 1.3–2x for large caps and 2–4x for small caps — meaning a 20% BTC drawdown often translates to 40–60%+ losses in the rest of the portfolio.
如何評估山寨幣
團隊：創辦人是否公開亮相且具有豐富經驗？請查閱 LinkedIn、過往項目及交付紀錄。
Tokenomics：總供應量是多少？流通量有多少？請確認 MC/FDV 比率高於 0.3（稀釋風險低）。團隊／VC 代幣何時解鎖？
代幣在生態系統中具有明確的用途——避免持有沒有清晰持有理由的代幣。
技術：代碼是否開源且經過審計？是否有已知漏洞或駭客攻擊事件？路線圖是否切實可行？
市場指標：查閱 CoinGecko/CoinMarketCap 上的市值排名，評估主要交易所的交易量與流動性。
團隊與支持者：知名 VC 的背書（a16z、Paradigm、Multicoin）是正面信號——但並不保證成功。
社群與採用：查看真實用戶活動（活躍錢包、交易量、DeFi TVL）。避免只有炒作而無實際使用的項目。
投資組合配置
✓ Conservative
80–100% Bitcoin, 0–20% large-cap altcoins (typically ETH and SOL), 0% small-cap. Prioritises capital preservation and minimises exposure to project-specific failure. Closest in risk profile to holding only spot-ETF eligible assets.
✓ Balanced
50–70% Bitcoin, 15–30% large-cap altcoins (top 10 by market cap), 0–15% mid and small-cap altcoins. Seeks growth from rotation effects while keeping the majority in the most liquid asset. A common framework for investors with a 3–5 year horizon.
✓ Aggressive
30–50% Bitcoin, 25–40% large-cap altcoins, 15–30% mid and small-cap altcoins. Maximises exposure to alt-season upside but historically experiences 80–90% drawdowns in bear markets. Suited only to investors who can hold through multi-year cycles and accept total loss on the small-cap sleeve.
黃金法則：只投入您可以承受全部損失的資金。任何單一小市值山寨幣的配置不得超過 5%。對波動性大的山寨幣採用 DCA 方式入場，而非一次性投入全部資金。在上漲途中逐步獲利了結——不要等待所謂的「完美頂部」。

衍生品及槓桿產品——重要風險警告
衍生品是複雜的金融工具，具有資金迅速損失的高風險。槓桿交易（futures、perpetual 合約、保證金交易、options）可能導致超出初始投資的虧損。大多數散戶投資者帳戶在交易衍生品時都會虧損。
你應仔細考量自己是否了解衍生品的運作方式，以及是否能夠承擔損失資金的高風險。本內容僅供教育目的，不構成財務建議、投資建議，或交易衍生品的推薦。
在歐盟，加密貨幣衍生品依 MiFID II 被歸類為金融工具。只有獲得適當 MiFID II 授權的平台，才能向歐盟居民提供這類產品。各司法管轄區的監管處理方式有所不同——在參與交易前，請先確認衍生品交易在你所在國家的法律地位。
