PwC’s CEO says clearer US crypto rules and stablecoin legislation pushed the firm to expand its digital asset services. PricewaterhouseCoopers decided to expand its crypto business after a shift toward clearer US regulation, citing new leadership at regulators and progress on stablecoin legislation, CEO Paul Griggs said. New leadership within US regulators such as the US Securities and Exchange Commission and new laws like the GENIUS Act were among the major developments that spurred PwC’s reversal, Griggs told the Financial Times in a report on Sunday. “The GENIUS Act and the regulatory rulemaking around stablecoin, I expect, will create more conviction around leaning into that product and that asset class,” he said, adding that “the tokenization of things will certainly continue to evolve as well. PwC has to be in that ecosystem.” Read more

The amount of crypto sent to Binance rose in the past week, but CryptoOnchain says the other side of the trade, the buyers, are yet to show up. Large crypto holders have been moving tokens onto Binance, a pattern analysts associate with potential selling, but buying demand remains muted. So-called crypto whales deposited $2.4 billion near-evenly split between Bitcoin (BTC) and Ether (ETH) to Binance in the past week, the exchange’s largest net inflow in a month, but the “buying power is missing,” CryptoOnchain said in a note to CryptoQuant on Sunday. “Crucially, this surge in risk-asset deposits was not accompanied by new buying power,” it added, noting that stablecoin net flows were “essentially flat” at an inflow of $42 million for the week, which was mostly tokens moving between the Ethereum and Tron blockchains.
