Does it have sense to start participating now? How much weeks left to the end?
you can get started and for the duration problem there it is very clearly mentioned I think you just need to read it carefully or maybe you can see it in bitcointalk version thread
here Thank you. So, 8 weeks totally and ends at 13th of October. Ok, I will participate.
What about the airdrop then? Your site is saying it will end before the end of September, is it true?
