What is Portfolio Risk and Where Does It Come From
Portfolio risk is the probability and magnitude of losses in your holdings. Main risk types: Market risk (systematic risk): broad market declines affect nearly all assets simultaneously (e.g., 2022 crypto bear market: BTC -65%, ETH -70%). Asset-specific risk (unsystematic risk): a single asset implodes due to a smart contract exploit or corporate fraud — can be reduced through diversification. Liquidity risk: unable to sell, or only at severely unfavorable prices (common with low-market-cap tokens). Concentration risk: putting 90% of assets in one position or one directional bet — any single-point failure causes catastrophic loss. The first step in understanding risk is not predicting the future, but stress-testing the worst case: if this investment goes to zero, can my account survive?
