The "gold + bitcoin" dual reserve mechanism of $BTC is Tether's hedging combination against the risks of sovereign fiat currency, providing substantial financial returns. Ardoino recently disclosed that Tether currently holds over 100,000 bitcoins and over 50 tons of gold. In 2024 alone, Tether's net profit reached 13.7 billion USD, with investments in gold and bitcoin contributing approximately 5 billion USD in profit. Ardoino has stated that they hold gold not to challenge bitcoin, but to challenge the centralized fiat currency system.
