Cold Staking lets users securely delegate staking powers to “staking nodes” which contain no coins. The purpose of these “staking nodes” is to provide a dedicated resource connected to a blockchain network and stake on behalf of another wallet without being able to spend its coins. In other words, it allows users to stake offline coins.
Benefits of staking
Staking enables coin holders to earn compounding rewards in return for freezing their staked coins so they cannot be otherwise used while they are being staked. Stack those coins!
Withdraw at anytime
Staked Coins aren't kept on the full node, so you and only you can withdraw your coins back to your wallet at anytime. No fee's or penalties.
