After seeing ads for Gas Alrex 4.0 (ascend-market-insights.com and vantage-wealth-analytics.com) online, I investigated. The company is listed in the IOSCO I-SCAN warnings database and has been flagged by Australian Securities and Investments Commission. Their website looks professional but that means nothing - many scam operations invest heavily in appearance. Always check the regulatory warnings before investing.
Pros: Website looks legitimate on the surface
Cons: Unauthorized firm|Found in IOSCO warnings database
