Hi, can you update with an argument to make the fee act every 12 or 24hours?
You can enable the dev fee as soon as the miner starts for the equivalent time and then the miner run the specified hours without have to change DAG..
If you make it as argument, people can use it if want or not

1. run miner
2. wait 11h59m
3. kill miner
4. repeat
Doesn't sound smart now, eh?
He is not loosing anything if he implemented it because the dev fee starts when you start the miner so there is no point in stopping the miner after 11h59m
