v0.4.1
You can enter an existing BIP39 mnemonic, or generate a new random one. Typing your own twelve words will probably not work how you expect, since the words require a particular structure (the last word is a checksum)

- Use path m/0'/0.
- For more info see the Hive Wallet homepage
+ Use path m/0'/0' with hardened addresses.
+
+ For more info see the + Bitcoin Core BIP32 implementation
- Use path m/44'/0'/0'/0.
- For more info see the Mycelium Wallet homepage
+ Use path m/0'/0.
+ For change addresses use path m/0'/1.

- You are not a good source of entropy. + Storing entropy (such as keeping a deck of cards in a specific shuffled order) is unreliable compared to storing a mnemonic. + Instead of storing entropy, store the mnemonic generated from the entropy. + Steganography may be beneficial when storing the mnemonic. +
