      Marcos Sargen's Review Sourced from Google

      Tech Alchemy is building KTO’s centralized exchange and, so far, it’s been quite pleasant with the UI, visuals, and functionality. Can’t wait for the beta test to test what they’ve been working hard on for months!

      Flora Castle's Review Sourced from Google

      Based on the experience I had: poor communication and customer service. Don’t seem keen to take on a challenge and take a long time to respond. I was surprised by this after reading other good reviews for this company.
