Yes, it's possible. 17th of April still gives you good amount of points as an early supporter, as you can see in this graph:
Then, you can score up to 50 points by doing the quiz with questions about the project. The date of the quiz is not announced yet.
Finally, you can get up to 30 points by making contributions to the Quarkchain community, for example: helping people on telegram, writing usefull articles about Quarkchain, youtube videos, etc.
If you score 60 points or more, you enter the lottery. It doesn't mean you can participate, it means that if you are lucky enough on the lottery, you can :)
