Oddly enough, in the case of other "Anonymity-Enhanced Cryptocurrencies" ("AECs"), the DoJ has taken the position that they'd rather not recirculate them. See <https://twitter.com/jerrybrito/status/1314254265251225600>, where it's reported:

> In most cases, the Department [of Justice] does not liquidate seized or forfeited AECs, as doing so allows them to re-enter the stream of commerce for potential future criminal use.

So note: if the DoJ auctions these off, it's "good for Bitcoin", as it provides further confirmation they consider them a normal form of property whose legal uses outweight any illegal uses.

On the other hand, if they refuse to auction them off, it's also "good for Bitcoin", as it permanently reduces the circulating supply, making all other units incrementally more dear.
