like any other asset that has a value and is seized by the law enforcement, bitcoin will also be auctioned and in that auction people can buy it at the rate that they offer and receive it in their addresses. this is not the first time and won't be the last.
Both BCH and BSV have their first transaction on that same day to another address, this is another indication that the address might be a target of hackers or its security details has been sold in the darkweb.
the government can also claim these shitcoins since they have a value and auction those too all in one bundle.
