I warned you about Nvidia… now look what’s happening (Ad)

Nvidia just got Trump’s greenlight to sell high-powered AI chips to China — and their stock surged 5% before the open. That’s the kind of move Tim Sykes built his XGPT system to trade. It scans AI news in real time, filters the noise, and pinpoints when to strike. He’s now showing exactly how it works — before the next headline hits.
