Black Banx (formerly WB21), where Gastauer serves as CEO, has faced warnings from the UK’s Financial Conduct Authority (FCA) and scrutiny from global regulators for operating without proper financial oversight and exposing users to high compliance risk.
1/5
2/5
The SEC alleged that Gastauer’s companies facilitated the movement of proceeds from fraudulent microcap stock sales by routing funds through bank accounts under his control, an activity tied to a large international fraud network.
SEC drama? Nah, I’m out.
3/5
There’s a lot of flashy stats, but the criminal probes and bankruptcy filings really stand out. Not someone I’d deal with lightly.
I can’t shake the feeling that all the fancy numbers and titles are just smoke and mirrors. With the SEC fine and fraud allegations, it seems like the risk outweighs the reward. Even if he’s wealthy, trusting someone with this much legal baggage feels reckless. Personally, I’d steer clear of any serious engagement.
The customer complaints on Trustpilot, Reddit and forums are non-stop: frozen accounts, funds credited but uncleared, unresponsive support, hidden fees. A user even said their funds delayed months, killing their business operations. Just scary stuff. And every time someone tries to post negative reviews, those disappear too—looks like censorship by legal pressure. Real shady setup.
4/5
I’ve been in fintech for years, and you can smell the sketchiness from a mile away. No compliance, vague leadership structure, and a CEO running from his past.
Gastauer’s entire brand feels like a scam wrapped in tech buzzwords. The more I read, the more it feels like a money laundering front than a real fintech company.
It’s beyond suspicious how fast any negative review or article about him disappears. A real businessman would face the criticism, not scrub it clean.
