For the second time, Alabama Senator Tommy Tuberville is set to reintroduce a bill aimed at allowing Americans to add cryptocurrency to their retirement savings plans.In a March 31 Fox News interview, Sen. Tuberville said he planned to reintroduce his “Financial Freedoms Act” legislation after two failed attempts to get the legislation through Congress in 2022 and 2023. In announcing the bill, the Alabama senator said he wanted to help US President Donald Trump’s perceived role as a “crypto president.” “Give people a chance to breathe for once […] let them do what they do best [which] is invest their money,” said the senator. The Financial Freedom Act, which Tuberville first introduced in the US Senate in May 2022, proposed scaling back regulations with the Department of Labor over the types of investments used in 401(k) retirement plan fiduciaries. The senator said he would reintroduce the bill on April 1, but congressional records showed no movement at the time of publication.Related: Trump-linked crypto ventures may complicate US stablecoin policyThis is a developing story, and further information will be added as it becomes available.

Asset manager Grayscale has filed to list an exchange-traded fund (ETF) holding a diverse basket of spot cryptocurrencies, US regulatory filings show.On April 1, Grayscale submitted an S-3 regulatory filing to the US Securities and Exchange Commission (SEC), which is required to convert the non-listed fund to an ETF. The Grayscale Digital Large Cap Fund, which was created in 2018 but is not yet exchange-traded, holds a crypto index portfolio comprising Bitcoin (BTC), Ether (ETH), Solana (SOL), XRP (XRP) and Cardano (ADA). As of April 1, the fund has more than $600 million in assets under management (AUM) and is only available to accredited investors (entities or individuals with high net worth), according to Grayscale’s website.The filing follows an Oct. 29 request by NYSE Arca, a US securities exchange, for permission to list the Grayscale index fund. Grayscale’s digital large cap fund holds a diverse basket of digital assets.

They have seen relatively modest inflows since debuting in February.  In February, the SEC acknowledged more than a dozen exchange filings related to cryptocurrency ETFs, according to records. The filings address issues such as staking and options for existing funds as well as new fund proposals for altcoins such as SOL and XRP. According to industry analysts, crypto index ETFs are a main focus for Wall Street’s issuers after ETFs holding BTC and ETH debuted last year. “The next logical step is index ETFs because indices are efficient for investors — just like how people buy the S&P 500 in an ETF. This will be the same in crypto,” Katalin Tischhauser, head of investment research at crypto bank Sygnum, told Cointelegraph in August.Magazine: How crypto laws are changing across the world in 2025

The use of hydrocarbon fuels in mining Bitcoin has seen a sharp decline over the past 13 years, with the use of coal energy in mining dropping significantly. The share of coal energy use in Bitcoin (BTC) mining has dropped from 63% in 2011 to 20% in 2024, an average annual decrease of roughly 8%, according to a new report released on March 31 by the MiCA Crypto Alliance in collaboration with the risk metrics data platform Nodiens.In parallel, the share of renewable energy used in Bitcoin mining has steadily increased, growing at an average rate of 5.8% per year.Bitcoin absolute energy consumption trends and share of renewable and coal energy.
