If your crypto exchange supports staking, you can enable it with a single click. Not every cryptocurrency can be staked though: To participate in the proof-of-stake, validators must own a specific amount of the currency.
You may be required to commit to staking your coins for a specified period of time. If your crypto exchange does not allow you to stake coins, you should consider shifting your holdings to a wallet or platform that does. When you stake your coins, you contribute to a validator node and earn a percentage of the validator's rewards. Staking is as straightforward as that.
