Is it possible to use Electrum+Trezor if the Trezor device was set up through https://mytrezor.com? Wallet schould be the same as on mytrezor.com.

Yes, exactly the same. Just set up as new wallet, not restore. It will get the master public key from the Trezor and you are good to go. I use mine with Electrum 2 and it was setup on myTrezor website.

So to use the existing wallet from trezor.com I have to choose:

What do you want to do:
-create new wallet

wallet type:
- Hardware wallet

right? Is there something else to consider?

why do we trust the Electrum server more than mytrezor.com server when it comes to tracking addresses used?

So you can have infinite and separated set of addresses at your own disposal based on the passphrase while having one single private key in the form of the seed? That's neat. Thank you.

That's not quite right. There's one mnemonic, that's the 24 word string. Combined with any (or no) passphrase, the mnemonic gets turned into the seed, and then the root private key. Each passphrase you use with the same mnemonic will generate a different root private key.

what's the correct way to visualize this? a tree with the root privkey at the top and a new branch extending downwards for each passphrase in a hierarchical tree?

Question: How many different passphrases does Trezor support?

over 9000

no, wait

all of them!

How hard are the passphrases to crack compared to bip38? I know there is some type of key lengthening....

I'm mostly curious how hard short passwords are to crack if you have the seed.

That'd be interesting to know, yes.

I know one thing: on each bruteforce attempt you have to query the utxo set to see if there are funds, because there's no other way to know wether or not you have found the correct passphrase. In fact you also have to check wether there address has been used in the past (and now has 0 balance so it's not in the utxo set any more) and/or query a couple more addresses in case the first one was left untouched. That alone should slow things down quite a bit.

The passphrase has to be entered via the pc, and there is no concealment from a rogue pc pin-cod style.

It should be nearly infinite (in the human sense), since the password is effectively a 25th word to the seed. There may be a character limit though.

AFAIK the trezor doesnt effectively store anything other than the PIN and the seed - so using dozens or hundreds of passwords shouldnt be an issue

how long do these things take to ship to usa? i feel like i ordered mine forever ago, hasnt come.

If you live in the USA it took 3-4 weeks before I received mine, which is wayyyy to long in today's world....but would you really trust receiving it from any 3rd party supplier? --Probably not...

The delay is all caused by US Customs very slow incoming processing of packages. I just received two Trezors last week delivered to Thailand in six days from ordering to receipt. Thai customs incoming processing less than one day. Left Prague day after being mailed. Arrived two days later and was delivered next mail day.

You didn't get a tracking number?

They leave Europe within a day or two. US Customs can take one to three weeks or longer to clear incoming packages. Even if trackable, they do not publicly track within US Custom's facilities.

Hi

I want to buy Trezor. Becouse it´s awesome.
It only stores BTC? (is here any HW wallet for altcoin?)

Currently supported cointypes by Trezor:
Bitcoin, Namecoin, Litecoin, Dogecoin, Darkcoin and Testcoin.

There is an independent developer who works on supporting NXT, seems that he will release it soon.
