This is the opposite of good to me. The United States gov is interested in value, period. Notice they arent keeping the bitcoin as a speculative hold, they are liquidating it. Just like they would any other seized asset.
I have huge issues with the way that the US takes property from suspected criminals, so I can see the potential for abuse here (lets go after someone we normally would not prosecute, because they are bitcoin rich). This also should correlate with increased scrutiny from the IRS (as apparently they are paying attention).
Not mad at this, but have seen the dangers of taking a bitcoin salary in a serious downturn. You need to be able to trade in order to do this, so the average Joe will lose value, and we all have bills to pay.
