When would it begin, the airdrop? Or is it already live. Is it allowed for it to be posted here?
The airdrop is currently live!
I would recommend dropping into the bounty chat if you have any questions
https://t.me/nynja_bountyGreat idea here but what are plans for sustainability, I mean future plans?
I'll use an excerpt from the whitepaper to answer your question

"We aim to continuously innovate, respond to customer feedback, and most importantly anticipate what our customers will need in the future.
This is where existing apps have fallen short, leading us to believe that NYNJA App will penetrate the market in a swift and far-reaching way."
By the looks of it, seems like you guys will need more customers for this to be a big bang. How do you plan on getting more users?
We plan on raising awareness through our airdrop and bounty campaign
It's quite a cool project, keep it up guys, support from HK
Thanks very much!
Will there be fee payment and how much is NYNJA coin worth?
It is free to use the NYNJA app, the only fee will be when hiring a freelancer. Token price has not been announced yet.
I wonder what is the total supply of Nynja token. And it subsequent growth value, will there be token lock down or token burn?
The total supply is 5,000,000,000 NYNJACoin. There is no planned token burn.
Will there be any commission fee for any business transaction within the app,and will the platform render it's full service to its users?
There will only be a fee involved in hiring a freelancer. The rest of the app is free

Quick question, just to be sure. Does the title 'NINJA' bear any hidden meaning apart form the real word meaning? Is it an abbreviation to something else?
No
