Tether CEO Paolo Ardoino has revealed how the company expanded its Bitcoin treasury by over 8,888 tokens during the last quarter of 2025.
Tether Has Purchased Another 8,888 Bitcoin
In a new post on X, Tether CEO Paolo Ardoino has shared the blockchain details of a Bitcoin transaction that the company made during the past day. With this transfer, the firm moved exactly 8,888.8888888 BTC from the cryptocurrency exchange Bitfinex to its BTC reserve.
Tether is a digital asset company best known for being the issuer of the stablecoin USDT. Stablecoins are cryptocurrencies that have their price pegged to a fiat currency and USDT, tied to the US Dollar, is currently the largest asset of this type in the world in terms of market cap.
Tether has been maintaining a Bitcoin reserve since 2023, when it announced that it will regularly be allocating 15% of its net realized operating profits to the number one cryptocurrency as part of a new investment strategy.
The company has since gradually been adding to the reserve, with the latest expansion announced by Ardoino corresponding to accumulation that occurred in the fourth quarter of 2025.
At the time that the transaction shared by the Tether CEO occurred, the new coins were worth $778.7 million. This latest purchase has taken the company’s total holdings to 96,370 BTC, equivalent to more than $8.46 billion.
For comparison, the second largest public Bitcoin treasury company, MARA Holdings, owns just 53,250 BTC ($4.68 billion). Thus, the firm’s BTC reserve is one of the largest in the world.
Though, while Tether’s holdings are very significant, they still pale in comparison to Strategy, the largest corporate holder of the asset. Led by co-founder and chairman Michael Saylor, the company has been accumulating the coin for years now, with the latest purchase coming just this Monday.
This buy, involving 1,229 BTC, took the treasury firm’s total holdings to 672,497 BTC to cap off 2025. At the current exchange rate, this massive reserve is worth more than $59.1 billion.
Bitcoin and the rest of the cryptocurrency sector have been experiencing a bearish phase since the top in October, but it would appear that this market shift hasn’t discouraged the likes of Tether and Strategy from accumulating more of the asset.
The bearish momentum in the sector has also affected the stablecoins. As data from DefiLlama shows, the market cap of these assets was following an uptrend between 2024 and the last quarter of 2025. Since October, though, growth has flatlined.

As mentioned before, Tether’s USDT is the most dominant stablecoin. It makes up for $187 billion of the $308 billion market cap attached to the sector.
