In March 2025, U.S. states like Kentucky, North Carolina, and Arizona advanced major Bitcoin and crypto bills to grow reserves and support mining.
March 2025 shows a strong push from U.S. states to adopt cryptocurrency as part of their financial systems. Lawmakers across the country are proposing and passing bills that support crypto mining, Bitcoin reserves, and digital asset investments. These moves highlight a growing view of crypto not just as a speculative tool, but as a strategic financial asset.
In Kentucky, major progress came on March 24 when the governor signed the “Blockchain Digital Asset Act” (HB701) into law. This law gives residents the right to hold their own Bitcoin and offers benefits to crypto mining companies. The Senate passed it with full support, 37-0. With access to energy from coal and hydropower, Kentucky is positioning itself as a major mining hub. In fact, it currently holds 11% of the total U.S. Bitcoin hashrate.
North Carolina is also taking bold steps. Lawmakers there introduced three bills to invest public money in digital assets. Bill H506 and S709 both allow up to 5% of state funds to go into digital assets, while H92 pushes that number up to 10% for strategic reserves. These proposals would allow the state to protect public funds from inflation and build long-term value through crypto investments. Lawmakers are working quickly, aiming to pass the bills in the coming weeks.
Arizona is following a similar path. Two bills—SB1373 and SB1025—were approved by the House Rules Committee. SB1373 allows the state treasurer to create a digital asset reserve using funds from seized criminal assets. The treasurer can invest up to 10% of the reserve and lend assets to earn more money, as long as the risks are controlled. SB1025 would let Arizona invest up to 10% of treasury and pension funds into Bitcoin. If the federal government builds a Bitcoin reserve fund, Arizona could store its holdings there for added safety.
Oklahoma is getting involved too. The state’s House recently passed HB1203, the Strategic Bitcoin Reserve Bill. This bill allows public funds from several state accounts to be invested in Bitcoin, stablecoins, and top-tier digital assets with a market cap over $500 billion.
Across the country, more than 20 states are now considering similar plans. According to Bitcoin Law, 23 of 50 U.S. states have introduced Bitcoin reserve bills. Matthew Sigel, Head of Digital Assets Research at VanEck, said these bills could bring up to $23 billion in Bitcoin purchases, or 247,000 BTC. This estimate doesn’t even include what might come from pension fund investments, which could increase if lawmakers go forward.
These state efforts are gaining momentum after the Trump administration showed strong support for Bitcoin. On March 7, the White House approved the creation of a Federal Strategic Bitcoin Reserve. This has opened the door for states to align their financial strategies with national crypto policy.
With this growing wave of state-level legislation, the U.S. is moving closer to integrating cryptocurrency into public finance. Whether it’s through mining, reserves, or direct investment, states are laying the foundation for a new kind of financial future—one where digital assets play a central role.
