United States government takes BTC from Dark Web criminal. What's the catch?

In the past decades, United States have been a pioneer when it comes to new technology, well in fact, with everything new in modern world. At least, the relevant sources that we use to gather information are saying that.

However, when it comes to blockchain technology and Bitcoin, we are getting different impression, from U.S officials, media and with individuals who are shilling "their" point of view. It feels like, the greatest pioneer doesn't like cryptocurrency, because it is volatile, criminal friendly and insecure.

Keeping all of that in mind, take your time to read U.S. attorney's signed document that was made after Feds nailed drug lord and confiscated more than 500 BTC and as many as that BCH from his wallet.

After reading this document, few questions popped up:

1. Does this mean that by confiscating and storing taken crypto, U.S. officially acknowledges its value?
2. How come the size (in units) of confiscated BTC and BCH are so close, 500 each?
3. Is it possible that U.S. government never sold any crypto that they confiscated in the past?
4. Does Roger Ver has any role in this story?

Comment bellow so we can start making sense out of this.
