According to Vitalik Buterin on Twitter, privacy in blockchain ecosystems is not about hiding everything, but about having control over what and how you share information (Source: @VitalikButerin, June 4, 2025). For traders, this emphasis on user-controlled transparency is crucial, as it aligns with evolving regulatory demands and can influence investor sentiment towards projects prioritizing privacy and compliance. This policy direction may impact the valuation of privacy-focused cryptocurrencies, such as Monero and Zcash, as well as Ethereum-based privacy tools, potentially leading to increased volatility and trading opportunities in the privacy coin sector.
