Is this app something that requires the token in order to use. Or could for example my parents use it if they wanted to chat with me? Without ever using a coin.
It should be ok for your family if you read the first page. Team will release the app first, then the wallet. If they make a token requirement, I'm sure it would not be too expensive (less 1 token, otherwise the app will be restricted to 64M users...). Services like this has to be for mass.
how much total suply dev
distribution only use signature campaign , because not open ico selling
Total Supply is 64,000,000. The airdrop was 1 month ago, I missed too, but we are lucky cuz the price is very low.
Signature campaign is on going, it could be close, you should send a dm to the dev to be sure.
