Cold storage has been innovated by My Coin Chain (MCC). MCC provides their customers the ability to create a wallet on a computer that will never touch the internet. You can manage your funds with no risk of attackers stealing your funds. Your private key data is stored in an offline computer, someone would have to physically access the computer to access your Bitcoins. Even if someone physically stole the offline system it would take them a lifetime to get through our military grade encryption. Cold storage through MCC is the most safe and secure way to store your Bitcoins. MMC gives you the convenience of a normal wallet for receiving and sending Bitcoins, while giving you the option to store your crypto for extended periods of time. When you would like to spend the crypto within the offline cold storage, MCC provides a simple interface for you to withdraw. There is no synchronizing required with the blockchain with the offline computer as there is no data required.
