If the United States really does announce a Bitcoin reserve, wouldn't it be more logical and easier for the country to just transfer the confiscated Bitcoins to its reserve?
Why sell and then buy again?
Because it would be ruled a conflict of interest in which the state has three parts in the same lawsuit.
Ross has agreed to forfeit these coins to the USMC, he needs to have the coins sold to take care of part of his deal, if the US Treasury, which by the way isn't allowed to buy anything from the markets would buy something the DoJ agreed from the USMC in the name of a convict Ross can start a lawsuit against them, it's a breach of that deal for the same party, in this case, the US state of being both the prosecutor, the victim, the collector, and the buyer.
Any lawyer would have the day of his life landing this case.
