I was right about SpaceX (Ad)

Jeff Brown predicted Bitcoin before it climbed as high as 52,400%, Tesla before 2,150%, and Nvidia before 32,000%. Now he says SpaceX is shaping up to be the biggest IPO of the decade - and three key milestones just confirmed it. In the past 21 days: SpaceX crossed 10,000 active satellites, Elon filed confidential IPO paperwork with the SEC, and another rocket launched 25 more satellites. Two-thirds of every satellite in orbit now belongs to one company. The public filing could drop any day.tc pixel
