Thats hard because each investment is exchanged for steem power. And you can't withdraw steem power just like that, you need to wait 3 month to withdraw all steem power investment.
So at the moment I prefer to have manual control over that. On the other hand, you can withdraw your delegation any time you want.
Oh!That's good
Now steem price is 2.00 + Please recover again your 2.50 vot...i just love the system
