Crypto roundup: Trump defends his stock trading, YZi Labs ranks No. 2 among active family offices in August
A wide set of crypto, regulatory and corporate developments landed over the past 24 hours, led by a new post from U.S. President Donald Trump, fresh family-office investment data, enforcement action in Australia, and a string of market and infrastructure updates across Bitcoin, DeFi and payments. Trump said on Truth Social that he had made "hundreds of billions of dollars" for the United States through stocks and other assets and added that he was doing it "for our country, not for myself." Reuters had previously reported that ethics filings showed Trump disclosed at least $220 million and as much as roughly $750 million in personal securities trades in the first three months of 2026. On the investment side, FINTRX data cited by Jiaoban Xinzhi Dian showed that Binance founder Changpeng Zhao’s YZi Labs ranked as the world’s second-most active family office in August, taking part in 10 funding rounds with a combined disclosed round size of $42.1 million. The same dataset showed family offices participated in 109 deals during the month, with disclosed financing totaling $16.9 billion. Elsewhere, Australia’s AUSTRAC said it had canceled, suspended or refused to renew registrations for 45 crypto and remittance businesses over the past year. Market commentary from Two Prime and Wintermute focused on Bitcoin’s rebound, ETF inflows and key price levels, while other developments included Liquid Network fund returns, Cronos’ rollback after the Tectonic exploit, Circle’s deal for Tazapay, and broader stablecoin and banking moves in Brazil, Switzerland and South Korea.
