What is interest rate Vega risk?

Could you please elaborate on what interest rate Vega risk entails in the context of cryptocurrency and finance? In simple terms, how does it affect investors and market participants when dealing with interest rate-sensitive assets? Does Vega risk specifically pertain to the volatility of interest rates or is it broader in scope? Furthermore, how can investors mitigate this type of risk and what strategies should they consider to protect their portfolios? I'm particularly interested in understanding its implications in the cryptocurrency market and how it differs from traditional financial markets.
