Each password in trezor is a new wallet with a new private key? But the good thing with the seed is that it restore all of my wallets? However I still need to know the passwords?
What do you mean by a password? A passphrase? Every time you enter a different passphrase, you get a different wallet. You will have to know the seed and the passphrase to access your coins in case you lost your wallet. Trezor does not store passphrases so they need to be entered after the PIN. You can learn more about passphrases
here.
In case I need to restore it on electrum and I have a second wallet with passphrase. Is it then easy in electrum to get access of my wallets with passphrases?
I'm not useing my coins so I don't really need segWit. But it's allways nice to have the possibility to do it since it's so expensive (or it was?) to send.
You should at least consider using nested SegWit (addresses starting with 3). Both of these wallets and all services support it. You will save a little on fees in the future. Fees have been low for a long time now.
Ok I'll sure do that!
Is it possible to have 2 wallets without any passphrases? And how do you guys solve the problem if you die and your family find the seed and they need to know the passphrase(s) to access your funds? Do you store that in a different location?
Only so I understod this correctly...
If I have the device I need the pin to get into it. Inside I need my passphrases to get access to my wallets? If I buy another trezor I can use the same recovery seed to get access to the wallets with the same passphrases? and the pin on the first device isn't included in the revovery seed and it isn't needed here?
If I or anyone else only have the recovery seed then they need to know the passphrases do get access to the wallets, and that is possible to restore in electrum (or another wallet supporting BIP39)?
If you think Trezor is better choice go for it, you can always try Ledger in future. Maybe you can also consider to move your coins completely offline to paper wallet (be very careful if you ever do this), since you say "I'm a hodler".
I don't understand, what is the difference if I have paper wallets and say "I'm a hodler" compared to if I have hardware wallets and say "I'm a hodler"?
