The cryptocurrency market is experiencing volatility as two prominent altcoins, Pyth Network (PYTH) and Optimism (OP), are set to undergo significant unlock events that could impact price dynamics. On May 19th, Pyth Network will release 2.13 billion coins, while on May 31st, Optimism will unlock 31.34 million coins, respectively. These unlocks could trigger supply shocks in the market. According to experts, these events have significantly impacted trading volumes and derivative positions. Open interest for PYTH has decreased by 50%, while short positions for OP are surging. Technically, PYTH struggles to hold the $0.12 support level, with a breakout above $0.215 being pivotal, while OP is at risk of breaking below $0.50 if it fails to maintain its current range. Overall, without notable volume and breakthroughs of key resistance levels, both altcoins face downward pressure.
