Is there any ETA for the demo app? And everyone can join it or only trough invites?
nope, i think this will be released after the crowdsale in late december or later. there is no info yet, how far the developement of the app has been.
I don't think it's the demo app, I think it's the end product, but not sure.
They didnt announce anything about demo, but the beta will be in June 2018.
And i also want to know if there is any video interview about this project.
They did announce something about the release of a demo, that's the reason why they have postponed their ICO.
We have been working hard on our demonstration app, but to make sure that investors get to preview the functionality of the GAT Wallet, purchasing process in the GAT Marketplace and the trading mechanics of the GAT Exchange we have pushed back the Public Sale date to December 15th, when 115 Million GAT Coins will go on sale for $0.20 USD (price fixed in ETH).
