Block reward - 3 DOGX is calculated for healthy economy and balanced for both miners and investors. Reward is 10% which is much less comparing to some other networks where supply is not clear and devs just keep crazy numbers.
Tx fee is Ethereum like.
This means that for each block, development will receive 0.3 DOGX, this is the same like having 10% of all hashing power, do you thinks it's fair?
