There are different ways to store access data to stored cryptocurrencies. Cold storage offerings – also known as offline wallets – are an approach that is considered particularly secure. In this case, data on the digital wallet is stored outside the Internet. These are cold wallets and thus the opposite of so-called hot wallets, which are connected to the Internet.
What Types of Cold Storage are there?
There are several ways to store your own coins and tokens via cold storage. A classic way is to note relevant information in paper form (paper wallet). Hardware wallets are also considered cold storage variants.
