What is the adverse effect of Vega?

Could you elaborate on the potential negative impacts of Vega in the cryptocurrency and finance realm? As a seasoned practitioner, I'm curious to understand how Vega, as a measure of risk sensitivity to changes in volatility, could adversely affect traders and investors. Does it lead to increased risk exposure? Does it hinder effective portfolio management? Or perhaps, does it pose challenges in hedging strategies? I'm interested in gaining a deeper understanding of the downsides associated with Vega in order to make more informed decisions in my practice.
