The "coins" are mined separately. ETI is listed and tradeable, EGAZ isn't. It's only used to secure the blockchain and pay transaction fees.
As we will have energy costs and equipment depreciation, are we obliged to mine EGAZ too? Since it will not generate financial return, which is the goal of most miners.
Hi, there is no obligation or limitation about mining one is free to mine ETI, EGAZ or both. EGAZ should generate returns as well. Once the final tail emission rate has been fixed then EGAZ inflation will converge to 0. The higher the hashrate will get the more costs miners wil have and thus ask for higher EGAZ transaction fees. Right now it's still very begining and EGAZ transaction fees are not adjusted to actual miners cost yet
