Thank you for giving us detailed answer, and clarifying questions. I want to know if I can be eligible for the competition by just depositing required ZEN right before the deadline, and withdrawing it right after the snapshot.
This is a good point and would make a big difference for some users. Also similarly, based on the competition terms, I read it that you need to 'Increase' your Zen balance by 1000 over the competition period. This means if you deposited a bunch of Zen before the competition started, that would not count for this competition and you would need to buy or deposit an additional 1000 to be eligible.
Competition period: 2018/05/26 00:00 AM to 2018/06/02 00:00 AM (UTC).
Rewards will be issued within 2 weeks after the competition. You can login and check the ZEN prize via Distribution History > Account Center.
It's based on the net increase in ZEN between date A and date B so you can either buy, or transfer your holdings there.
