Stablecoin issuer Tether has added 8,888.88 Bitcoin (BTC) to its reserve wallet just as Q3 2025 came to a close, according to on-chain data from Nansen and Arkham.
The transfer, flagged at 11:06 a.m. UTC Tuesday from a Bitfinex hot wallet, was worth roughly US$1 billion (AU$1.53 billion) at current prices. The receiving address, starting with “bc1qj,” has been linked to Tether’s prior quarterly transactions and now ranks among the world’s ten largest single BTC addresses.
The unusual figure mirrors a similar 8,888 BTC allocation at the end of Q1, consistent with Tether’s May 2023 policy of putting 15% of its net profits into Bitcoin each quarter.
