Billfodl vs Cryptosteel Capsule Solo
Key differences
- Both cost $99, but Billfodl is lighter and more compact, while the Capsule Solo is heavier and more rugged.
- Billfodl is optimized for 12-24 word BIP39 phrases, while the Capsule supports multiple formats including BIP39, SLIP39, Monero, WIF, and even custom keys.
- Both use tiles, but Billfodl uses a flat slide-in system, while the Capsule stacks tiles into a cylindrical core—some may find Billfodl's layout easier to read and manage.

★★★★★
Kevin M. (Jan 2022)
'The quality of the product itself was outstanding, came with an entire set of characters to use for any kind of password/s you may want to protect. There was even a poster explaining different levels of information security/protection methods. Overall a worthwhile buy if you have enough value you need to protect.'
