Where can I stake Ankr?

Hey there, I'm new to the world of cryptocurrency and I've been hearing a lot about staking Ankr to earn rewards. But I'm not quite sure where to go to stake my Ankr tokens. Could you please guide me on the different platforms or wallets where I can stake my Ankr? Are there any specific requirements or fees that I should be aware of? I'd appreciate any insights you could provide on the process and the potential returns I can expect. Thanks in advance for your help!
