These are different agencies that barely talk to each other. The US government isn't as corrupt as most of you think. They are required to auction seized assets by law.
This is not about corruption. This is about a potentially huge game-changing financial technology arriving much faster than anyone is anticipating.
Do you honestly think they will just auction them like any old junk confiscated from criminals?
Until they feel like they understand Bitcoin properly (which could take a while) those coins will not go anywhere.
1. US agencies generally don't conspire with each other in grand plots. They might ask for help on a single given issue (one arrest), but they don't scheme to invent new rules. "Hey, Senator, this is so-and-so from the FBI. I have these coins here and we don't want to auction them. I want you to hold a hearing with Treasury, DHS and SS and, oh yeah, make sure the SS guy is against it to make it look good. And let's have some guy tie it to child porn for an hour just in case we need to kill it later." <- That didn't happen.
Yes. I am 100% certain that they will follow the law and auction them once the trial is over.
Until the trial is over and DPR is found guilty, these coins will not go anywhere. As soon as he is found guilty, they will be split up into lots and auctioned publicly. I can assure you that this will happen.
