Speculation: 1. Qian Zhimin's cryptocurrency is being sold, approximately 61,000 coins. The US government is forcibly liquidating it. 2. Chen Zhi's cryptocurrency is being sold, approximately 100,000 coins (not from the batch seized by the US). Chen Zhi has been back in China for a month and has reportedly purged himself. The Chinese government is forcibly liquidating it. 3. Maduro's cryptocurrency is being sold. Maduro has been detained for a month, the timing matches. The US military is selling it, fearing it might be transferred back to the US and controlled by the Ministry of Finance; this is less likely. In short, the counterparty doesn't treat Bitcoin as an asset at all; they're dumping it at the exchange's market price. Only law enforcement could do this. It's unlikely to be a European or American family fund or institution; they habitually use it as collateral to obtain funds, not liquidation. That's basically it. You've been given a chance to get on board; thank you to the counterparty.
