Binance's $1 billion Bitcoin fund address has not made any purchases yet

Binance announced on January 30 that it will gradually convert its original $1 billion stablecoin reserve into Bitcoin, with funds sourced from the SAFU fund, and plans to complete this within 30 days. However, on-chain information shows that three days after the announcement, there has been no buying activity from the SAFU fund address. This situation may be related to the weekend timing.
