Yes becase of the hard work of them the project collected a good amount in their ICO. In the current market it is not easy to collect that much many of the projects fail in their struggle but as this project has a solid business and a talented team so everyone invested in this project.
One of the reason is that this project already have a well established product/platform so it attracted a lot of investors. Most times it happens that after the ICO the projects are unable to prepare the product so the investors lose their money but when they invest in a project with already prepared product then they get a solid profit.
