Fred Thiel, CEO of Marathon Digital Holdings (MARA), has declared Bitcoin a national security concern for the United States. Thiel emphasized the importance of the U.S. maintaining dominance not only in Bitcoin mining but also in holding Bitcoin assets within U.S. companies. He suggested that the price of Bitcoin will surge once U.S. banks are able to custody and collateralize it. In line with this strategy, Marathon Digital has significantly increased its Bitcoin holdings, now owning over 26,200 Bitcoins valued at $1.5 billion. Additionally, MicroStrategy plans to purchase $2 billion worth of Bitcoin soon.
