Okay if thats the case, why is my btc address not listed on the receive tab then? All i see is main account for it. I have to go History tab to see the btc address for this one...
Because every time you receive a payment a new address will be presented for payments once you restart electrum or click new. All addresses show in the history tab are valid and can be resued. If a used address has a zero balance click the arrow next to used and it will show you all prior used addresses that now have a zero balance. You are thinking about bitcoin wrong. There is no main account and you don't actually have a wallet and you don't actually possess any bitcoin. Balances are held in addresses in the blockchain. Only the person with the private (secret) key can spend the bitcoin but anyone can look at the addresses in the blockchain to see how much btc is in that address. That is why programs like Electrum try to use a new address for every transaction; to keep how much bitcoin you own in total private. The seed is used by a deterministic heuristic algorithm to generate addresses. It can generate an infinite number of address and private keys. |

So in other words, the btc address that i used to receive the first btc from a site, i can no longer use it anymore. is that correct?
Thus i have to use whatever 5 addresses are currently available in the receive? Then once i use the first one, then if i want to receive btc again, that one is no good anymore and i have to use the ones below that?
No, that is not correct. You can resuse a btc addresss as many times as you want forever. Each time btc is received it is an input to that address. When you send money inputs are put together until there is enough btc to cover the amount you are sending plus the fee and the change is returned. It is suggested you use a new address each time for more privacy, as reusing an address repeatedly can help anyone attempting to link a particular address to who owns it. You do not have to use a new address. For many purposes, like payments from people, you give them an address once and they repeatedly send btc to it. You can even give out an address to any number of people. The number of times you reuse is address is up to you. |

Every time you send BTC you DO send the entire amount of each input to an address up to the amount being sent plus fee and includes inputs of other addresses as necessary. Every time you receive btc to an address it is a separate input and are entities upon themselves. What you don't spend is returned as "change" usually to a new address, which is commonly referred to as a change address. The bitcoin protocol does not allow any portion of a input to be spent. Each time the entire input is sent. So if you have 1 bitcoin in one address as one input and you send someone .05 btc with a .0001 tx fee, 0.9499 btc will be returned to you as change, usually to a new address unless you clicked the option in electrum to not use change addresses, then the change will be returned as a new input to the same address it was sent from. Every time you receive money, electrum will show a new address to receive the next payment and each time you send btc a new change address will be used.

Hw1 and ledger are similar.
Ledger have better casing and a two factor card.
I would chose ledger because it's more resistant, but it's same smartcard chip as HW1.
I have two HW1, a BWallet and a Trezor. My favorite is Trezor because I can use it with Electrum 2.0 and the BWallet website is slow and buggy. HW1 is a very decent hardware solution for the price but Green Address, what one normally uses with HW1, is very sluggish but it works okay (no way to change fees, must accept what Green Address decided to charge). If you rent 30 GH/s of power from MRR for three days and mine on Slush you can get a Trezor for only $79.00 (bought two this way). If you buy a Trezor click link in my sig please. Trezor is what I use as my daily wallet. |

Each password with any given seed will generate a completely new master public and private keys. Think of it as a completely new tree.
Now I'm a bit confused. I don't get it how master seed+password work. Can I recover coins with master seed if I forget the password? No. If you use a password and forget it the coins are lost forever. What if I disable the password and have only one PIN? If I forget the PIN can I recover the coins only with the master seed? Yes, the PIN only protects the hardware on the device from being used without entering the PIN first. If you stop using the password and forget the PIN you can recover the coins from the seed. But be sure to send any coins in your password protected wallet out to another wallet before removing the password protection. Then after removing the password protection send the coins back to the Trezor. |

It worked, thanks. It is not a trezor problem it is a mytrezor.com problem. Is using electrum with trezor safe? I suppose that it works in a same way as mytrezor.com, private keys and trezor password are never exposed to the electrum, right?
Yes, it is completely safe. The Trezor just provides Electrum with the public master key to derive the receiving and change addresses. When you send bitcoin each input is sent to the Trezor for signing with the private key (which never leaves the Trezor) and then the signs the transaction. The complete and signed transaction is then broadcast to the bitcoin network by Electrum. In no way is your Trezor exposed any more than using MyTrezor.com. The seed is safe and never revealed in any way, unless you tell it to someone. |

This is getting really weird, I cannot send any BTC from my trezor. I can receive but not send. I do get a txid like this, https://blockchain.info/tx/5f2432dcf9c9ebed5624d3c020be14cae4079c4329e60dac5bc87e693cf63649but it is impossible to see it on the blockchain. What is happening? Anyone else experiencing the same problem. I have 4 transaction stuck like this. I am really worried, I did a trezor recovery this morning from the seed but this is still going on! It appears as if your transaction was never broadcast to the bitcoin network. Install the new version of Electrum. It will work with your Trezor and works well. Just create a new hardware wallet and it will get the master public key from your Trezor and you will be good to go. If there is some problem with the mytrezor.com website it is possible that the transaction maybe broadcast later so I would avoid double spending the coins for at least 12 hours to see if the transactions go through. |

None of my accounts have balances visible.
I noticed that the 2nd Gen pre-shares are back though.
*sigh*
At least he is not selling them. Out of stock. |

Last message while things get sorted. Again no personal response will be answered to avoid user conflict. It is aware of threats made and noted users that continue via means other than forum.
Thank you for patience and understanding of work undertaken over past months, applicable information ie. mods, tax and balance are exprected within next days upgrade.
VERY IMPORTANT anyone found accessing via brute force or unfamiliar ip will be hardlocked and require further verification. This was made clear over numerous updates.
Again to clear confusion access is by ltcgear website only, mirrors do not exist anylonger. What should this mean? With this paragraph he could lock out everybody as he likes. Yes, I think that is his plan now. Will make up an excuse to lock everyone out of their account. |

"We are applying some updates - will be back in short time. "who is "we"? is there a team behind this scam? you know that this can be continued for ever and ever  Maybe Queen Elsa and her royal court? |

what is up with the mytrezor page having captchas now? Is that normal? Today is the first time I have seen that...
I never encounted a captcha on the mytrezor.com site. |

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? picture it like bitcoin mining almost. The 24-word seed is like the list of transactions. The password (25th word of the seed) is like a nonce - any value will work, and can create millions of possibilities. isn't each passphrase generated set of addresses a separate branch of the HD tree? however, it sounds like no further sub-branches can be built under each branch? Each password with any given seed will generate a completely new master public and private keys. Think of it as a completely new 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. That's a different attack. The question was how long would it take (in relation to passphrase length) to bruteforce the passphrase if someone finds your paper seed backup. That would depend on the length and complexity of the password and if anything about it was known to the attacker. With a strong password it could take thousands of years. Once quantum computers are mainstream it could possibly be brute forced within minutes but by then Bitcoin protocol would have changed to a quantum alogorithm. |

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? Yes, if there is a selection button click Trezor and it will query the Trezor for the public master key and that will be save under the wallet name you previously gave it when you said new wallet. If you start Electrum without the Trezor connected it will say error, watch only mode. If you want to send just plug in the Trezor before starting the send transaction and it will ask for your PIN (if you have one) and then sign the transaction. Easy and works well. |

Yes. 1 hour left for the last 5 hours. I thought the counter was just going to reset for another 36 hours. This is a twist.  He stopped the game clock.  |

I'll not put another bit into this if we don't get SSL or 2FA, we're looking at more problems.
Assuming current bullshit might actually be resolved sometime. and yes that is a major/unlikely assumption. But looking forward anyways...
My prediction. The lockout extensions continue in "waves." |

what is this united community vs divided community?
I dont understand can u plz explain?? Valid question! I find that very debatable. This is an easy one. Half the Bitcoin community like DigiByte, the other half don't so they are divided. Whereas all of the DigiByte community like DigiByte, so they are united! But everyone hates PayCoin2 so all are united on that point.  |
