Can we still apply for beta or is it too late?
You can still apply for BETA
www.zeex.me/beta
How long will the BETA testing last?
The Beta testing end date has not been announced but, I think would be better if you immediately register if you want to test it because the team wants to get more feedback that will be useful to help them in developing the product
Any rewards for beta testers?
No rewards available for Beta testers but, you can participate in ZEEX Bounty campaign to get rewards https://bitcointalksearch.org/topic/bountyico-zeex-crypto-to-product-no-fiat-no-fees-rewamp-4579968
Are you thinking of increasing the reward pool for the bounty?I must say it is quite low...
I agree, given the great interest for this project, they might have a slight raise reward pool for the bounty
makes no sense - only means that more people are competing for the bounty
