An Ethereum paper wallet may be perhaps the most secure option for storing your Ethereum. Basically, it’s a piece of paper with code written on it. The biggest advantage is that it does not need to be connected to the internet or installed on your computer. This piece of paper can be carried around at any time, kept in your safe, or even buried in your backyard. It makes your funds invulnerable to cyberattacks, and even protects against most types of physical theft (depending on how well you hide them).
