PayPal expands stablecoin push as crypto assets factor into Q2 results

Global payments giant PayPal reported its second-quarter earnings, highlighting stablecoins and AI-driven payment tools as key strategic focuses, while also noting crypto assets affected its earnings. Q2 earnings were $1.26 per share, slightly below estimates of $1.28, but revenue of $8.68 billion exceeded expectations. The company recorded an $81 million adjustment related to gains and losses from strategic investments and crypto assets, which it excludes from its non-GAAP results as these are not actively traded. PayPal is expanding its efforts in areas like agentic payments, stablecoins, and biometric technologies, leveraging its existing payments network and infrastructure. Additionally, its PayPal World platform facilitated around $200 million in payment volume between Venmo and PayPal.

A New Era Begins in Institutional Crypto Investment: Morgan Stanley Introduces Investors to Two Giant Altcoins!

Morgan Stanley continues its expansion into the cryptocurrency investment sector. Its investment management arm has launched two new exchange-traded funds (ETFs) focused on Ethereum and Solana, which have begun trading on the NYSE Arca. The funds, named the Morgan Stanley Ethereum Trust (MSSE) and Morgan Stanley Solana Trust (MSOL), track the price movements of Ethereum ($ETH) and Solana ($SOL), respectively. They follow the firm's earlier launch of the Morgan Stanley Bitcoin Trust (MSBT). A key differentiator for these new products is their incorporation of staking support. Morgan Stanley aims to provide investors with additional yield by staking a portion of the underlying ETH and SOL assets and states it will not retain any portion of the staking rewards earned. This move is part of the firm's effort to expand its product portfolio to meet growing investor demand for cryptocurrency exposure.

Police Expose Pseudo-Crypto Academy: Scammers Cheated Nearly a Thousand Ukrainians Out of $1.1 Million

Ukrainian police have exposed a fraudulent organization that posed as a "Ukrainian Financial Academy" offering cryptocurrency investment courses, defrauding nearly a thousand citizens of over $1.1 million. The scam, advertised on Facebook and Instagram, targeted vulnerable individuals, including pensioners and people with severe illnesses, who lost savings intended for medical treatment or housing. After victims expressed interest, fraudsters gained their trust, convinced them to transfer money to controlled accounts, and displayed fake profits on a bogus platform. Some were allowed small withdrawals to encourage larger investments. When victims tried to recover funds, their accounts were blocked, and they were pressured for additional payments under false pretenses. In one case, a cancer patient lost approximately 500,000 hryvnias meant for treatment. Organizers also coerced victims into taking loans or recruiting others. Police conducted searches in Kharkiv and Dnipropetrovsk regions, detaining four key suspects. They face charges of large-scale fraud as part of a criminal organization, with possible sentences of up to 12 years in prison and asset confiscation.

Study: 90% of Influencers' Financial Advice on Social Media is Ineffective

New research from Queen Mary University of London confirms widespread suspicions: nearly 90% of financial advice from social media influencers is ineffective or low-quality, often lacking proper sources, disclaimers, or genuine expertise. The study analyzed nearly 2,500 influencers on Instagram, TikTok, and YouTube and surveyed over 4,200 UK adults. It found that while two in five UK adults use social media for financial advice, only about one in ten consult a licensed professional. Complementing this, a Chainalysis report on 2024 crypto tokens revealed that 74,037 newly launched tokens displayed patterns of "pump-and-dump" schemes, with 94% of these cases involving the wallet that created the liquidity pool also conducting the asset dump. The median suspicious scheme lasted less than a day. In a coordinated April 2026 operation, the UK's Financial Conduct Authority (FCA) and 17 global regulators targeted this issue directly, flagging 120 influencer accounts for removal. These accounts were responsible for 1,267 illegal financial promotions that reached at least 2.3 million UK accounts, with 66% of the ads linked to entities already on the FCA's warning list.

Robinhood Crypto Chief Reveals: 'Barbell' Customer Acquisition Strategy with Meme + Tokenized U.S. Stocks, Each Business Line Already Generates Billions in Revenue

Robinhood's Crypto Strategy: Leveraging Memes and Tokenized Stocks as a Dual-Pronged User Acquisition Strategy Robinhood Crypto GM Johann Kerbrat outlines the platform's "barbell" strategy for its new chain, launched three weeks ago. This approach targets two distinct user bases simultaneously: meme coin traders and those seeking exposure to tokenized real-world assets (RWAs), particularly U.S. stocks. The chain, built on Arbitrum technology, prioritizes accessibility and aims to onboard Robinhood's 27 million funded accounts. The vision is to fuse DeFi's benefits (like 24/7 trading and yield) with CeFi's user-friendly experience, eliminating wallet complexities. Key products like "Robinhood Earn" (for stablecoin yields) and tokenized stocks (available in 120+ countries) exemplify this hybrid model. Kerbrat downplays direct competition with Coinbase's Base, emphasizing growing the overall market for tokenized assets instead. Future plans include expanding RWA offerings to international stocks and private markets, positioning Robinhood's app as a comprehensive "super app" for diverse financial needs, from trading and banking to financial education. While all business lines currently generate significant revenue, the chain's immediate focus is on optimizing user adoption over maximizing direct revenue from transaction fees.
