This round will go for one month, June 8th-July 8th. There will probably be a third round, but maybe a small gap in between (it may start July 10th or something). There's still more time to go in this event, but if we do a third round, you won't have to do anything except register your address again to participate.

Make sure at the end of this round that you don't just delete the Qtum QT wallet. Last round we sent out 2Qtum to all of the participants at the end of the round. I'm not promising we'll do that this round (it's up to Patrick) but it will allow you to easily participate in the third round if you keep the application updated.

I can't answer why all the grand prizes were sent out in the first week, it's likely random. There will be an event at the end of the round where luck is based on online time.
