OST Investor Losses Mount Amid Shift from Optimism to Devastation

Ostin Technology Group (OST) collapsed on June 26, 2025, wiping out over $950 million in market capitalization. A class-action lawsuit alleges a coordinated promotional campaign used fabricated investment advisor identities, AI-generated deepfake videos, and WhatsApp groups to create an illusion of institutional endorsement. Individual losses ranged from $7,000 to over $1 million. Victims reportedly received promises of 80% to 300% returns despite OST's negative profit margin and lack of earnings surprises.
