160k btc is worth $64M at $400/coin. It's a drop in the bucket. The Fed prints 40X that amount in USD on a daily basis.
Which raises the interesting question: if they win their case against Ulbrecht, and the right to keep the coins, what will be signalled by the moment and method thay choose to liquidate?
Should whatever exchange they use be happy — chosen by the FBI! — or fear it's a trap?
Might the Feds be signalling, based on inside info of upcoming enforcement, that the BTC/USD rate is at a local maximum?
