No wonder the price collapsed again because of this negative sentiment that the US government will sell all the proceeds from confiscated bitcoins.

The news is that the US government still has around 209K bitcoins is that true? If so maybe the US government will sell on a scale.

You can see this transaction where the US Government sent the mentioned amount of bitcoin to Coinbase.
