Previously, BlockBeats reported the "BTC OG Insider Whale" acts on behalf of a dormant Bitcoin OG address holding over 50,000 BTC. Its operations have closely aligned with former President Trump’s remarks and U.S. policy trends. Shortly before the October 11 market crash, the address established a $500 million BTC short position, netting nearly $100 million in profit and drawing widespread market attention. BitForex CEO Garrett Jin noted the address is linked to some of the exchange’s clients.

On December 19th, Michael Saylor noted in an interview that while Bitcoin’s price has underperformed (dropping from $100,000 to $87,000), the past year has seen unprecedented progress in regulation, institutional adoption, derivatives markets, bank credit, and fair value accounting—laying the groundwork for global adoption. Bitcoin, he added, represents an economic energy breakthrough that can boost human economic longevity. Additionally, Saylor is bullish on quantum computing, arguing it will trigger a network upgrade and deflationary event. He takes a conservative stance on changes to Bitcoin’s protocol, advocating against unnecessary feature expansion to preserve its core role as a digital asset.
