Great

11 March, is the time and time zone of the ann known too?
Nothing official about the time of the announcement, but I have the feeling that Alejo likes to make his announcements after a cup of tea

(maybe around 4PM UTC)
Q: regarding the cold staking
Are you re-staking the whole CLO reward back? Cause I'm not sure if am I doing it correctly

, I'm staking via
https://wallet.callisto.network/After the staking period is over, at 100%, I click on "Claim Reward" button, than I choose "Start Staking" again to put the whole amount back on staking
Q2: If I need to take the whole staked CLOs back, can I do it by clicking the "Withdraw" button?
A: Yes I do

and personally, I prefer "Withdraw" and "Start staking", but yes you can do that, just be careful, because sending CLO to the Cold Staking during a round would reset your counter to zero.
A2: Indeed by clicking on the "Withdraw" button you get your CLO deposit + your reward, and if you want to send it back to the cold staking contract just click on "Start Staking".
