If there is hack then this mean the project will be very big, and for others don't be worry as there is warranty
It's a big project and it was expected that it will be sold out easily therefore there are people who like to take advantage
to do their thing stealing investments. Good thing centra is monitoring it well and they were able to see the problem early.
I also following this project this is really nice approach like dev team is moving forward this ICO. They are trying their best to keep this ICO alive and make the secure the people's investment into this project. I also believe this will be really big project in future.
