The Ballet Real Bitcoin is a non-electronic physical cryptocurrency wallet designed by Bobby Lee (co-founder of BTCCC). It stores private keys on a physical card using a two-factor key generation process — part of the private key is printed under a tamper-evident sticker, and the other part is added during manufacturing. Ballet wallets are designed as physical bearer instruments for gifting and storing cryptocurrency without any electronic components.
