Tether CEO Paolo Ardoino revealed during his Plan ₿ Forum keynote in Lugano that the company holds about 150,000 BTC (~$11.5 billion) — roughly 50,000 more than its latest Q3 reserve report implies — confirming the additional coins are held outside $USDT backing as proprietary investments. Ardoino did not say where the extra coins sit or when they were acquired, noting that holdings outside USDT reserves, such as Tether Investments' positions funded from excess capital and profits, wouldn't appear in the BDO-attested reserve report.
