Investors Urged to Anchor Crypto Portfolios with Bitcoin, Ethereum Amid Volatility

Investors constructing a cryptocurrency portfolio should build on blue-chip assets Bitcoin (BTC) and Ether (ETH) to manage risk, a strategy guide published June 5, 2026 advised. Conservative allocations of 1% to 5% of total investable assets can offer exposure without derailing long-term plans, while aggressive investors may allocate up to 10% or more. Dollar-cost averaging into core assets is recommended over market timing. The guide suggests devoting 50% or more of a crypto portfolio to BTC and ETH, citing their market-cap dominance, institutional adoption, and resilience across market cycles. Altcoins in sectors like DeFi or Layer-1 chains can add growth potential but should not exceed 1%–5% of the crypto allocation per speculative asset, given that over half of all launched cryptocurrencies have become defunct. Self-custody wallets are advised for long-term holdings to avoid exchange risks. Periodic rebalancing—selling overperforming assets to lock in gains and re-weight to targets—is highlighted as a critical discipline to curb emotional trading amid double-digit daily swings common in digital assets.
