So according to document[1], the "accounts" they want to seize are cryptocurrency addresses? How is that supposed to work? Are they expecting the cryptocurrency developers to hard fork the network so ownership can be transferred to the DOJ? Are they expecting exchanges to blacklist those addresses? What's preventing the original owners from laundering them again to get past that?
The entire design of bitcoin seems designed to thwart this. Maybe the goal is make this wallet address poisoned so that no one will be willing to move the bitcoin anywhere. Then you can't exchange it or shuffle it, because everyone will be afraid the us govt will come after them. The money is marooned.
