The Ballet REAL Series wallet was intentionally designed as a bearer asset like cash or gold; whoever has physical possession of it controls all of the coins stored on it. There are a few reasons why we decided to make it this way:
- It is ready to use right out of the box; no computer setup required.
- It is the perfect way to give cryptocurrency as a gift.
- You only need to worry about the physical security of one item, whereas multiple backups are multiple targets for theft.
Technically you can make a backup of a Ballet wallet simply by removing the tamper-evident sticker and scratch-off material and copying the private key entropy and passphrase entropy elsewhere, but then the wallet is no longer a bearer asset and you have to be concerned about protecting multiple items from theft. Definitely avoid making a digital backup on an online computer.
