MGO had a successful ico because people saw the potential in a coin with a real world use. It hasn't done that well in the short term due to issues with the eth token used, but it will list on trex soon so expect a price hike
Yes mgo had a successful ICO and it attracts more investors. I expect it will return to its ICO price. Though they have a good project and dev said they have partnered with large gaming companies. So, I believe price will recover and those who hold mgo coin will earn huge profit.
