    Delaware Moves to Establish State Framework for Stablecoin Issuers

If passed, the measure would further Delaware’s longstand...

    Bitcoin Price Slides but Holds Up Better Than Stocks as Oil Shock Continues

    Bitcoin has fallen over the past week, but its declines have been less severe than the broader equity drawdown since the Iran conflict began on February 28. The world’s largest crypto traded around $68,000 on Sunday, down roughly 2% over the past 24 hours and about 6% over the past seven days, according to CoinGecko data.  The move comes as the Iran war entered its fourth week, pushing crude prices higher and contributing to a broader pullback in risk assets by Friday.  That geopolitical backd...

    Bitcoin Trails Money Supply Growth as Energy Costs and Rates Bite

    Bitcoin is trading at a steep discount to global liquidity trends, according to new analysis from CF Benchmarks, even as macro headwinds tied to energy prices and monetary policy complicate the outlook for risk assets and economic growth. Global M2 money supply has risen about 12% since mid-2025, while Bitcoin has fallen roughly 35% over the same period, the Kraken-owned index provider said.  One model cited in its report, published Thursday, implies a “fair value” of about $136,000, compared w...

    Gemini Shares Rise After Hours as Investors Back Shift Beyond Crypto Trading

    Gemini shares climbed in after-hours trading on Thursday after the crypto exchange business reported a shift toward more stable revenue streams and outlined an expansion into prediction markets, even as trading activity declined. The stock rose about 7% to $6.45 in late trading after closing at $6.01, as investors appeared to focus on its improving revenue mix and cost-cutting efforts rather than weaker volumes. The company reported fourth-quarter trading volume of $11.5 billion, down 30% from...

    Why Bitcoin Is Falling Despite $1.1 Billion in ETF Inflows

    Bitcoin continues to struggle to maintain a foothold at elevated prices even as institutional investors continue pouring money into the asset, hinting at a growing disconnect between short-term macro pressures and longer-term demand.

Wednesday saw its first daily outflow of around $129 million, according to CoinGlass data, as prices declined about 4% following a shift in inte...

    Australia Senate Panel Backs Crypto Framework in Latest Regulatory Push

    Why Bitcoin's Price Is at a Weekly High Despite Middle East Tensions

    Post-Quantum Shift Could Force Crypto Exchanges to Rethink Wallet Security

    A widely used method that crypto exchanges rely on to generate deposit addresses while keeping private keys offline could break if blockchains migrate to post-quantum cryptography, according to new research. Exchanges such as Coinbase and Binance currently rely on hierarchical deterministic wallets, a system standardized under Bitcoin Improvement Proposal 32, or BIP32.  The design allows operators to generate fresh deposit addresses from a public key stored on a server while the private signing...
