Try to make also your first transaction with a small amount so that you can verify whether the things you learn is right or that you are doing things right.
Bitcoin has the Testnet wallet, an easy way to try the amount of transaction how to know how it's work. Newbie has a big risk to try the Mainet where never has experience sending a transaction before. example :
Sending 0.01 BTC using Fee 2.66038352 BTC Hell, even I, with my humble experience, know the difference between a seed phrase and a private key!
Good, but optional passphrases aren't protected a private key like PIN and microcontroller right?. because if using a passphrase a wallet will generate a different private key, not the same as seed without a passphrase.
