Zcash (ZEC) has shown a significant bullish signal, with the TD Sequential indicator on a 12-hour chart suggesting further gains. Crypto analyst Ali Martinez highlights the potential for ZEC to reach $642, provided it maintains support above $500. This comes after ZEC's impressive performance, surging nearly 1,000% over the past year and 50% in the last month, despite broader market challenges. The privacy-focused cryptocurrency has been a hot topic on social media, with Santiment noting its dominance and a peak social dominance score of 10.02 on May 20. A short squeeze on that date propelled ZEC from $568 to $686, triggering $28 million in liquidations and boosting its market cap above $11 billion. The rally was driven by aggressive trading, thin liquidity, and excitement over Grayscale's ETF filing. In addition to market movements, the Zcash Foundation released Zebra 4.5.0, urging node operators to upgrade due to security vulnerabilities. The update includes fixes for consensus issues and introduces mining support to shielded addresses, enhancing network security and reliability.
