Solana (SOL) enters May with $78 as a critical support level following a decline in April spot Solana ETF inflows, which fell to $39.93 million, marking the weakest month since the ETF's launch, according to SoSoValue data. A head and shoulders pattern suggests a potential drop to the $56 zone if the neckline is breached. However, the decreasing sell volume and historically positive performance in May provide a basis for a potential rebound.
