The sanctioned ruble-based stablecoin A7A5 claims daily trading volume exceeding 100 million, but companies like TRM Labs and Elliptic question the accuracy of this data.
PANews reported on July 4th that, according to CoinDesk, the sanctioned ruble-pegged stablecoin A7A5 is embroiled in a heated dispute with a blockchain analytics firm over its actual usage and trading volume. A7A5 claims that cryptocurrency data providers underestimate its trading activity, while the blockchain analytics firm states that trading volume for this ruble-backed token has declined significantly this year. The A7A5 issuer claims that it processed a total of $34.4 billion between January 1st and June 17th, 2026, with an average daily trading volume of approximately $205 million, primarily driven by DeFi activity.

ING: Nvidia's profit margins are threatened by customers developing their own chips.
According to Mars Finance, on July 7th, Jan Frederik Slijkerman of ING wrote in a report that Nvidia's ability to maintain profit margins is uncertain as tech giants develop their own chips. He pointed out that major customers such as Microsoft, Alphabet, and Amazon are developing their own custom chips to help control AI infrastructure costs (capital expenditure efficiency). He stated that, therefore, Nvidia's pricing power may face more intense competition than in recent years, making it more difficult for it to maintain its currently extremely high profit margins in the long term, despite the company's expansion into new business lines.
