Zcash (ZEC), Starknet (STRK), and Ethena (ENA) have emerged as the worst performers in the crypto market, starting December with significant declines. Over the past 24 hours, all three tokens have fallen by double digits, continuing their downward trend from the previous week. Zcash's price has dropped below $400, with a 10% decline amid increased selling pressure, as Ethereum co-founder Vitalik Buterin warned against token voting, potentially impacting its privacy model. Starknet is down over 5%, facing a key support level at $0.10, while Ethena has experienced a 5% drop on Monday, following an 8% decline on Sunday. Technical indicators for all three tokens, including RSI and MACD, suggest strong bearish momentum.
