COURSE 2 - 2.3. Seed generation: 24 words, BIP39, dice
QUICK INFO:
Reference: armantheparman.com/dicev2/
Imperative: use a secure and cold computer, Tails OS, Persistent Volume.
Generate seed: follow the video instructions. The actual .xlsx file shown on video is available in the Member area. Of course, it has no malware etc. but don't trust: recreate the file by yourself (copying and pasting the formulas makes the process quicker)
Save the vital info (Seed, BIP39 passphrase, derivation path) to KeePassXC in Tails Persistent Volume (and make one or more backup copies of Tails' Persistent Volume) and/or save this info in physical format (e.g. paper or metal)
Create a wallet in Electrum: "Applications" > "Internet" > "Electrum Bitcoin Wallet" > "Create New wallet" > give wallet a name > "Next" > select "Standard wallet" > "Next" > select "I already have a seed" > "Next" > paste seed you created manually using dice > click "Options" > tick "Extend this seed with custom words" (this is the BIP39 passphrase); select "BIP39 seed" > "OK" > make sure that it says "BIP39 (checksum: ok)" > "Next" > type chosen BIP39 passphrase > "Next" > select "native segwit p2wpkh" > "Next" > provide wallet password (generate it in KeePassXC and paste it) > select "Encrypt wallet file" > "Next" > done!
Note vital and additional info in KeePassXC:
Seed;
BIP39 passphrase;
derivation path;
BIP32 root fingerprint ("Wallet" > "Information");
Master Public Key ("Wallet" > "Information")
Find wallet in Places: "Places" > "Home" > click on the three lines icon > "Show hidden files" > double click the folder ".electrum" > .double click the folder "Wallets": find the wallet.
