Trump's crypto bank just got approved (Ad)

Here's a detail almost everyone missed about last October. When crypto stumbled in October 2025, Trump's crypto team was only half built. His SEC chairman was in place. But the man now running the CFTC, crypto's other main regulator, hadn't even been nominated yet. This October is the first where both seats are filled with Trump's own picks, working from the same playbook... And the market already seems to sense it. Bitcoin just posted one of its strongest summers in years, gaining in both August and September. ETF buyers just had their biggest week since last fall. That's the backdrop heading into crypto's favorite month.tc pixel
