Cube Exchange operates a hybrid crypto trading platform that combines fast off-chain order matching with secure on-chain settlement. Users’ funds are kept in multi-party computation (MPC) wallets, distributing key material among the user, Cube, and independent guardians, so assets remain non-custodial and visible on the blockchain. The platform supports native settlement to Bitcoin, Ethereum, and Solana (with plans for more Layer 1s) and offers spot and futures trading with competitive fees. This setup avoids custody by the exchange and eliminates the need for wrapped assets or proof-of-reserve audits. Differentiators include a non-custodial MPC-based custody model, a founder-led emphasis on reducing founder risk after exchange collapses, and leadership from veterans with experience in traditional finance and the Solana ecosystem. Cube’s goal is to provide fast, transparent trading while keeping user assets under user control across multiple networks.

Mangoceuticals (MGRX), a telemedicine-focused health and wellness company, has partnered with Cube Group, a digital asset treasury firm, to establish a new digital asset treasury (DAT) strategy with a target capacity of up to $100 million in Solana (SOL), according to a new press release. Mangoceuticals plans to leverage its Nasdaq listing to raise capital through at-the-market equity offerings to fund the phased accumulation of SOL. The strategy provides investors with a proxy for Solana's ecosystem growth and institutional-grade DeFi yield strategies. "This Solana-focused DAT strategy represents a pivotal evolution for Mangoceuticals, blending our commitment to innovation with the immense potential of digital assets," said Jacob Cohen, founder and CEO of Mangoceuticals. MGRX has filed a trademark for "MULTI-DAT," a framework covering virtual currency transactions, fund transfers, portfolio management, and blockchain-based crypto operations. The initiative includes a Digital Asset Treasury 2.0 strategy with staking, tokenized assets, DeFi infrastructure, and stablecoin treasury tools, starting with actively managed SOL staking targeting 7 - 20% annualized yields. "This initiative not only capitalizes on Solana's superior yield opportunities but also sets a new standard for corporate crypto strategies, paving the way for exponential growth in a rapidly evolving market," Bartosz Lipinski, Co-Founder and CEO of Cube Group, stated.

While gold is hitting new highs, the oft-touted “digital gold” has failed to keep up.Bitcoin proponents have long claimed that the cryptocurrency’s unique selling point is that it’s a long-term store of value, just like the precious metal. And the biggest and oldest virtual coin has in the past performed like gold.But that isn’t happening right now. Gold today hit a new all-time high of $2,483 per ounce as geopolitical instability—particularly in the Middle East—and hopes the Federal Reserve will soon slash interest rates have created more demand for the shiny commodity.Meanwhile, Bitcoin’s volatility is soaring and its price is 17% lower than the all-time high it hit in March of $73,747. Why?Bitcoiners like Custodia Bank CEO and founder Caitlin Long have previously said that more investors flock to the biggest digital coin during times of uncertainty due to it being a scarce asset—since only 21 million Bitcoins will ever be produced.But while that may have briefly been the case during the banking crisis of 2023, when Bitcoin’s correlation with tech stocks dropped, it isn’t now. “I think what we’re seeing here is that investors don’t yet move into Bitcoin during periods of uncertainty,” Kaiko research analyst Adam Morgan McCarthy told Decrypt. “It failed to attract safe haven flows in April [during an escalation of conflict in the Middle East], it has done so again now, and is more often correlated with equities during heightened periods of stress in the market.”Amberdata’s director of derivatives Greg Magadini added that while gold and Bitcoin should be correlated, there are other forces at play: the U.S. election in November.Republican frontrunner Donald Trump has come out as the crypto-friendly candidate—at least more so than the Democratic Party’s Kamala Harris. But as odds have increased for Harris becoming the next U.S
When it comes to the global market selloff battering Bitcoin’s price on Monday, a focus has emerged on whether traders that borrowed the Japanese yen are this rout’s culprit.The yen’s value has strengthened 10% against the U.S. dollar within the past month, according to TradingView data. Meanwhile, the price of Bitcoin has fallen 20% in the past week, dipping below $50,000 on Monday for the first time since February.A so-called carry trade is rapidly being unwound, Jake Ostrovskis, an OTC Trader at the market maker Wintermute told Decrypt. The popular trade involves borrowing the yen at “historically low interest rates to invest in higher-yielding assets elsewhere,” he said.If the yen’s value falls or stays low, traders are able to make a profit simply by holding assets denominated in other currencies, such as the dollar. On top of that, the returns can be juiced by yields or investing those converted funds into other assets.Last week, The Bank of Japan (BOJ) raised interest rates for the first time in 17 years, however, which increased yen borrowing costs. Signaling more rate hikes are “in the pipeline,” the BOJ’s move made a yen-based carry trade “unattractive,” Ostrovskis said.“As they sell risk assets and convert back to yen, the yen has strengthened,” Ostrovskis explained, adding that “risk assets like equities, and cryptocurrencies have experienced increased volatility and downward pressure” as a result of those positions being closed.As traders buy up the yen to close out their positions, it can also result in more pain for other yen borrowers
