Bitcoin’s Strongest Ally in the US Senate Is Leaving Office

The 71-year-old said she doesn’t have six more years in her.

Cynthia Lummis, an American attorney and politician serving as the junior United States senator from Wyoming since 2021, said she will not seek reelection.

She is known as a long-term supporter of bitcoin and other cryptocurrencies who spearheaded several attempts to introduce pro-digital-asset legislation.

After thanking her home state for the “incredible honor” to represent it in the US Senate, she admitted that she doesn’t have six more years in her to operate on this high level. She said she feels like a “sprinter in a marathon” and added that “the energy required doesn’t match up.”

Lummis was among the first and most vocal politicians to openly support bitcoin when most of the US administration was against the asset class. Some previous reports indicated that she first bought bitcoin back in 2013.

She continued accumulating throughout the years, with filings from 2021 showing that he bought somewhere between $50,000 and $100,000 worth of the cryptocurrency. The senator has made multiple pro-BTC comments over the years, including predicting that it will become an important player for a long time to come.

More recently, she championed the idea of a US strategic Bitcoin reserve. She has introduced numerous pro-crypto bills in the US, but her push for a strategic Bitcoin reserve has perhaps become the most widely praised and discussed.
