Possess limited elemental tokens on the blockchain
Each mine will start producing elemental tokens after reaching certain conditions, and the output rate will be half-decayed every two months. Much like bitcoin, the only difference is that you do not need to buy a miner and do not need power, as long as you own the mineral rights. And the number of elemental coins will be very small, we expect only 1000,000 per element.
Note that the output elemental tokens, you need to collect their own wallet in a timely manner. Otherwise, the next buyer will have both your elemental mineral rights and the uncollected elemental coins.
