According to @1HowardWu, the current financial system relies on transaction privacy, suggesting that full public visibility on blockchains could deter mainstream use and trading activity (source: Twitter). This highlights the urgent need for privacy solutions like zero-knowledge proofs and privacy coins, as traders and investors may avoid public blockchains without enhanced privacy options. The adoption of privacy-focused protocols could significantly influence crypto liquidity, trading volumes, and institutional participation, making privacy a critical factor for sustainable market growth.
