#CryptoSecurity101 crypto portfolio is a collection of digital assets held by an investor, typically including cryptocurrencies like Bitcoin, Ethereum, and altcoins. Diversification is key to managing risk, often spreading investments across sectors such as DeFi, NFTs, and Layer 1 or 2 projects. A well-balanced portfolio considers market cap, utility, and project fundamentals. Investors may also allocate portions to stablecoins for liquidity. Active portfolio management involves rebalancing based on market trends and risk tolerance.
