The most time-efficient way to stake is by using your preferred Cardano wallet. Again, we strongly discourage staking on an exchange, as mentioned above, since they control your ADA and take that out of your hands. This, in our opinion, goes against the nature of a decentralized blockchain and ecosystem, but the decision is ultimately up to you. Using your wallet is safe, simple, and effective.
