Having just a piece of paper as cold storage is no longer a priority for Bitcoin users. Now they want to have cool cards or accessories that simultaneously protect private keys and QR codes.
And while writing down or printing out crucial information may help protect one’s account from online hackers, it is wise to remember that paper is not resistant to environmental damages.
For more secure offline wallet options, some people choose coins with hidden information, others prefer nice wooden bitcoin wallets, while a lot of other Bitcoin enthusiasts prefer slim and colorful cards.
Luckily for those who prefer the last option, there are several merchants who make offline wallets that are not just useful, but also stylish AND resistant to damage.
