An investor with a cryptocurrency portfolio who does not execute trades in a week faces several risks. Market volatility: The prices of cryptoassets like Bitcoin or Ethereum can fluctuate significantly in a few days due to news, regulations, or macroeconomic events, impacting the value of the portfolio. Regulatory risk: Changes in laws or government policies, such as restrictions on exchanges or taxes, can affect the liquidity or legality of holdings. Security risk: If cryptocurrencies are on an exchange or in an insecure wallet, there is a danger of hacks or technical failures. Opportunity risk: Not trading can mean missing out on buying or selling opportunities in a dynamic market. Macroeconomic risk: Factors such as inflation, interest rates (like FOMC decisions), or trade policies (Trump tariffs) can negatively influence. To mitigate them, diversification, secure storage (cold wallets), and passive market monitoring are recommended. (165 words)
