Good morning guys, I just joined Cardano network, I am using Yoroi wallet but I don’t understand how ADA staking works. I will appreciate some articles to read to get myself use to the network. I discovered that my staked ADA is still in my wallet but I saw ADA delegated to Kiwipool as my available ADA in my wallet. Is this okay. Also can I unstake my ADA anytime? What’s the duration for unstake?
