Powering-up is different from delegating.
When you power-up someone else, you are giving her/him your HIVE and can't get them back unless the person is willing to do so.
When you delegate, you still own your HIVE and can get them back whenever you want (with a 5 days delay).
Ok, I didn't know that.
And how do I know when someone has already been turned on by someone else that day?
Should I put that information in a post or not?
