is the coin already in the exchange?
i'm wondering if it can be mine just by a laptop, why not a phone as well. seem like it doesn't require much resources to generate heat. if it can provide a dapp for us to mine using just out phones it would be a cool idea to start collecting this as well. i'm just not very positive when it comes to listing this on exchange which cost a lot today.
It's still not available in exchange because this is still a testnet. It might still take quite a long time to optimize everything and be ready to be released. Idena Mining only uses a stable internet network that is very easy and fast, but if you do mining now you will still get a balance according to your wallet when the release time later. That's all I know from the founder of this project.
