If your voting power went down while you were sleeping you should go to steemd and check why. Someone might have accessed your account.
It is important to me that the person I delegate to builds their own account. So let me know if you are interested Self voting is a requirement.
I made up my mind. I won't apply myself but I'd like to suggest three German language accounts:
@steemarity, a charity project co-initiated by @limesoda and run by a group of university students
As for my voting power, nothing has changed but the exchange rate SBD <> USD, I think. Other users confirmed that.
