Hello. Please tell me in order to 6% per annum, the wallet needs to be online all the time?
No. You can send xxx Cloak to a wallet, then close it. When you switch it on after some time you'll get the share of the 6% yearly when your coins are staking.
That is, I filled up your wallet, let's say 1000 cloak and can close the purse and shut down the computer. Then I can turn the computer through one year and to 6% after the synchronization. Do I understand correctly?
