Michael Saylor, executive chairman and founder of Strategy, has advocated for a maxi-sized Bitcoin reserve in the United States, arguing that it would ensure cyberspace dominance for the next century and strengthen America’s lending power.

Speaking at CPAC in Washington D.C., Saylor advised the U.S. government to purchase 20% of Bitcoin’s (BTC) supply for the much-anticipated national strategic reserve.

“There’s only room for one nation-state to buy 20% of the Bitcoin network,” Saylor said, adding that he “thinks it should be and will be the United States.” U.S. authorities would have to buy 3.9 million Bitcoin in addition to its current 207,000 BTC trove to realize Saylor’s vision. That endeavor would cost  $392 billion at today’s prices.

The U.S. Senate is considering a more conservative approach. Senator Cynthia Lummis of Wyoming has proposed that the U.S. accumulate 5% of Bitcoin’s supply, while President Donald Trump’s crypto team is currently assessing the feasibility of a BTC reserve.

At CPAC, Saylor reiterated that the U.S. must be the nation to capture 20% of the Bitcoin network:

“It’s a way for us to enrich ourselves and emerge as a creditor nation in a matter of a decade. It’s also a way for us to ensure we’re the economic leaders in cyberspace for the next 100 years.”

Saylor explained that U.S. adoption of BTC will drive a sovereign rush for the asset among both allies and rivals alike. Strategy is the world’s largest corporate BTC holder, boasting nearly $50 billion in Bitcoin. The company plans to raise another $2 billion to buy more BTC.
