According to the analysis of chain analyst @ai_9684xtpa, the US government marked an address that has just transferred about $2 billion worth of BTC to a new address. The address of about 29,800 bitcoins transferred this time is used to store some tokens seized by Silk Road in November 2020 (a total of 69,369 coins). The last operation was four months ago. This operation may be for selling, or it may just be a regular fund transfer, because there was also a wallet fund transfer operation on April 2. The specific situation depends on the follow-up.
