According to Bitcoin Magazine, billionaire investor and founder of Draper Associates Tim Draper stated on the Bitcoin Magazine podcast that government spending has not slowed down, which will only lead to two outcomes: hyperinflation or interest rates high enough to collapse banks.

He further explained that when banks holding cash fail, not having any Bitcoin on the board will expose legal and financial risks.Additionally, Draper linked his $250,000 Bitcoin price target to the next halving event and the subsequent supply shock.

According to CoinDesk, the Bitcoin Volatility Index BVIV's perpetual contract was launched on Hyperliquid on Monday, allowing traders to bet on the magnitude of Bitcoin price fluctuations rather than the direction directly on the on-chain exchange. The BVIV index is often referred to as the "Bitcoin VIX," which tracks the expected implied volatility of the cryptocurrency over the next 30 days in real-time, similar to the Chicago Board Options Exchange VIX index that tracks the implied volatility of the S&P 500 index.The newly launched perpetual market allows traders to directly go long or short on the volatility index without needing to express their volatility views indirectly through costly options tools that require derivative expertise. The perpetual contract uses USDC as collateral and pricing asset, initially supporting up to 5x leverage. The Seda oracle infrastructure is responsible for connecting the Volmex index to the Markets exchange on-chain.Cole Kennelly, founder and CEO of Volmex Labs, stated that the launch of the BVIV index perpetual contract on Hyperliquid provides crypto traders with a convenient tool for volatility hedging and speculation.

Hyperliquid is the world's largest decentralized perpetual contract exchange, with an average daily trading volume of several billion dollars and a fully diluted valuation of over $90 billion.

The U.S. House Financial Services Committee passed the amended H.R. 8957, the U.S. Reserve Modernization Act, with a vote of 28 to 21, aiming to incorporate the U.S. strategic Bitcoin reserve and digital asset reserve program into federal law. The bill proposes that Bitcoin legally held by the federal government and without other statutory purposes must be held for at least 20 years from the effective date of the bill, during which it cannot be sold, exchanged, auctioned, pledged, or disposed of in any other way.The bill still needs to be passed by the House, the Senate, and signed by Trump. The bill also requires the Treasury Department to establish relevant reserves within 180 days of its enactment and to publish an annual reserve certification report covering holdings, transactions, and private key control. The Treasury Department and the Department of Commerce will study legal and budget-neutral ways to increase Bitcoin holdings, but this provision does not authorize direct purchases.
