Upexi's shares fell sharply after the company filed to raise up to $1 billion to expand its Solana treasury and support token-related initiatives. The company's Solana holdings, currently at 2.1 million SOL valued around $262 million, have lost over half their value since mid-September due to a broader market downturn. Despite a massive DDoS attack on Solana's network, the blockchain maintained stable operations, demonstrating increased resilience.
