I also want to indicate to those who are new to Idena mining that its easy to mine Idena with a toggle switch once you are validated as at least Newbie.
But there is a catch..If you close your machine or client without deactivating mining switch, you get penalty if you are disconnected for more than an hour.
In addition you can turn it off just by clicking again the mine button before closing your pc but if you are using VPS I think it can run 24/7 so there's no need of closing it but in case you have some errand to do and you need to close the computer you are using to mine you can close it so you will not get any penalty.
