❓ Altcoin Investment Strategy

How much should I allocate to altcoins?
Safe allocation: 60% Bitcoin & Ethereum + 40% altcoins. Of that 40%, split into: 20% top 5 (Solana, XRP, Polkadot) + 20% others. Altcoins = higher risk = smaller position.
Which altcoins have the highest upside potential?
Highest risk/reward: Arbitrum (L2 scale), Polkadot (interop), Chainlink (RWA). These have "10x potential" but also crash 50%. Only invest what you can lose.
Should I hold or trade altcoins?
Hold = 80% wins. Altcoin trading is harder than stocks (more volatility). Use DCA: buy $50 monthly regardless of price. Trading = emotional rollercoaster + taxes.
What about altcoin staking for passive income?
Best staking altcoins: Solana (7.7%), Polkadot (12-15%), Cardano (3-5%), Cosmos (18-20%). Staking + price appreciation = double win. But lock-up periods vary (14 days to 28 days).
