Under the 2012 STOCK Act, members of Congress and other government employees must disclose stock, bond, and cryptocurrency trades above $1,000 within 45 days of execution. Those filings are meant to curb insider trading and market manipulation, and they also offer a public view into which digital assets appear most often in lawmakers’ portfolios.
Bitcoin remains the most common crypto holding
Bitcoin is the most widely reported crypto asset among US lawmakers. Senator Cynthia Lummis of Wyoming, one of the best-known voices on crypto policy in Congress, disclosed her first Bitcoin purchase in 2013. Other lawmakers who have reported BTC purchases include Senator Ted Cruz and Representatives Byron Donalds and Guy Reschenthaler, with some individual holdings disclosed at up to $250,000.
Some lawmakers also gained Bitcoin exposure through ETFs rather than direct purchases. Representative Sheri Biggs and Senator Dave McCormick were listed with exposure through products from Valkyrie, VanEck, and Ether. Others reported investments tied to Bitcoin-related companies instead of holding the asset itself. Senator Sheldon Whitehouse, for example, disclosed positions in PayPal, BlackRock, and The Block, formerly known as Square.
Ethereum ranks second, followed by Solana, XRP, and Cardano
Ethereum came in second based on the disclosures cited in the report. Representatives Mike Collins and Barry Moore both reported ETH holdings, with Collins disclosing up to $60,000. Representative Marjorie Taylor Greene and Senator Dave McCormick were also listed as investors in Ethereum ETFs.
Solana ranked third and XRP fourth, both reported by Representative Guy Reschenthaler, with each position valued at up to $15,000. Cardano was listed fifth. Representatives Barry Moore and Mike Collins disclosed ADA holdings, and Moore’s reported position reached as much as $45,000.
Smaller tokens also appeared in disclosures
Beyond large-cap assets, a few lesser-known coins showed up in congressional activity. Representative Mike Collins purchased Ski Mask Dog (SKI), while Representative Madison Cawthorn held and promoted LGB Coin. Other names mentioned in the same group were The Graph (GRT), Velodrome (VELO), and Aerodrome Finance (AERO).
According to the CoinMarketCap data cited in the source, most of these cryptocurrencies rose over the past 24 hours, posting gains between 1.8% and 4%. SKI was the outlier, falling 2.86% during the same period.
