They’ve been around a few years now. The parent company is FUTU Holdings (Nasdaq: FUTU). Moomoo has 2.1K ratings on the Apple App Store with a 4.7/5
They’re getting pretty big... I’d say about half the size of Webull. What’s great about them is they also offer trading starting at 4am, just like Webull. Most brokers don’t start that early.
Reading my response above you’d think I work for them or something lol.
