$BTC Crypto protocols Optimism (OP), Sui (SUI), ZetaChain (ZETA) and DYDX (DYDX) are set to unlock $330 million in scheduled events this week. These four cryptos unlock between 1% and 7% of their circulating supply. Traders should be cautious as token unlocks frequently generate negative sentiment among investors as they represent an increase in circulating supply, weighing down prices.
