Now with the release of the Stratis ICO Platform I had a look on the Documentation. I have to admit that i had a wrong perception on the ICO-Platform. Comparing it to the Apple-App-store is just wrong.
The Stratis ICO-Platform is a web-server-infrastructure deployable via Microsoft Azure. It contains everything to manage ICOs. With the Azure deployment you can integrate the service on your website. Stratis provides this user-friendly infrastructure free of charge.
Even though my faulty perception Stratis could still host a platform where all (Stratis ICO-Platform)- ICOs are bundled and displayed for interested investors.
