nate ( @picokernel had this same idea where you just make the power up a DELAY so if you WANt power you have to WAIt for it but the power DOWN is INSTNT so youd be MUCH more likely to power up MILLIONS of dollars if you knew you could get it back Instantly! the power UP should have the delay!
But maybe not thers a reason they didnt implement it that way, but we can experiment these features on our own test net style steem forks where we will get to test out all these types of features
Great minds think alike ;)
