Investment Strategies

Portfolio Allocation

Effective altcoin portfolio construction requires strategic allocation:

Conservative Approach (70% BTC/ETH, 30% Altcoins):

• Focus on established altcoins (top 20)
• Emphasise utility tokens with clear use cases
• Limit exposure to speculative projects

Balanced Approach (50% BTC/ETH, 50% Altcoins):

• Mix of large, mid, and small-cap altcoins
• Sector diversification across DeFi, Layer 1s, etc.
• Some allocation to emerging trends

Aggressive Approach (30% BTC/ETH, 70% Altcoins):

• Heavy focus on small and micro-cap projects
• Early-stage investments and new launches
• Higher risk tolerance for potential high returns

Timing Strategies

Dollar-Cost Averaging (DCA):

• Regular purchases regardless of price
• Reduces timing risk and emotional decisions
• Works well for long-term accumulation

Alt Season Rotation:

• Rotate from Bitcoin to altcoins during alt seasons
• Monitor Bitcoin dominance as indicator
• Take profits during peak altcoin euphoria

Sector Rotation:

• Move between hot sectors (DeFi, NFTs, Gaming)
• Follow narrative and market attention
• Requires active monitoring and quick decisions

Risk Management

Altcoin-Specific Risks

Altcoins carry additional risks beyond general crypto volatility:

• Technology Risk: Bugs, exploits, failed upgrades
• Regulatory Risk: Potential classification as securities
• Liquidity Risk: Difficulty selling during market stress
• Team Risk: Founder departure or misconduct
• Competition Risk: Better alternatives emerging
• Narrative Risk: Falling out of favor with investors

Risk Mitigation Strategies

Diversification:

• Spread investments across multiple altcoins
• Diversify across different sectors and use cases
• Avoid over-concentration in single projects
• Include both established and emerging altcoins

Position Sizing:

• Limit individual altcoin positions to 5-10% of portfolio
• Use smaller positions for higher-risk projects
• Scale position size based on conviction level
• Consider market cap when determining allocation
