Yeah, mining simply isn't worth it at this point unless you have dedicated hardware such as ASICs and cheap power. Mining on a laptop is a sure fire way to overheat and damage the laptop. And a USB miner will be quite slow at mining and you'll likely end up losing money anyhow. Not worth the hassle.

Thank you, everyone, who posted here to help me. I appreciate it. Fortunately, I was able to restore it with my seed, and I thought it was going to generate different addresses (Well, I didn't know that it came from that, but still, it's awesome. As for my old cold storage, I'm resetting everything and right now, I'm cleaning the drive. Planning to use it again for online purposes. Thanks again to those who posted, this thread could be closed.
Great! Glad to hear it. You should be able to close the thread yourself by the way. Check the lower left of the thread for a lock topic button. |

Couple of things. As you read above there are at least those two ways to accomplish the task. My preference would be to create a new wallet using the original wallet's SEED. Its a way to be 100% positive that your seed is accurate. All the addresses will exactly match the original if the SEED is correct. You can also backup the original wallet file and save that on the new Desktop as a "double" backup if you wanted to. Wallet files are very small. A concern for me, which I wanted to remind you of. What are your plans for the computer that was formerly hosting your Electrum cold wallet? When Thomas designed the cold wallet feature of Electrum the primary strength came from the fact the machine would never see online anything. If you are going to use that machine in any way, especially online, than consider doing a forensic clean of the disk area in question (if not the entire disk) so there is NO chance those SEED remnants will ever escape into the internet "wild"!! This is the sole purpose of the COLD WALLET design --- its cold!!
True, that is good advice. I suppose that could also be one argument for creating a NEW cold wallet on the new PC rather than just importing the old one. You wouldn't have to worry as much about what you do with the old PC and its seed after migrating the funds to the new one. |

I know that Blockchain.info has made their new online wallet a lot more newbie friendly where you don't have to understand which addresses funds are stored in to send, etc.
I personally hate as a more advanced user as it gives you much less control over individual addresses, but new users to Bitcoin might like the ease of use I suppose.

Yeah, the Letter of Guarantee is the only evidence you have of where the coins were supposed to end up. It looks like Helix might use something called a "Helix Verify String" instead of a Letter of Guarantee and there should also be a page at the end that shows you where the funds will be sent. You would want to double check that the destination addresses were correctly in your wallet.

Yep, there is really no need to transfer the funds to a new wallet. You can easily restore from the seed as previously mentioned or you can copy over your Electrum data folder and start using it on the new laptop without issues. On Windows, you can copy over Users/YourUserName/AppData/Roaming/Electrum and for Mac/Linux it will be in |

Its definitely better then using a web or a desktop wallet and Its with no doubt one of the best hardware wallets out there. Not only It supports multiple crypto currencies but Its possible to recover your wallet using a seed too If something goes wrong. Its also possible to use it on an infected computer without worrying about losing your coins unlike desktop/web wallets.
Yeah and integration is built in for a number of desktop wallets as well including Electrum/Mycelium/etc if you don't want to use Ledger's own wallet. |

Thanks so much!!
The button is green
My balance shows as 0 (and yes I do understand that the fee was deducted)--could the mbtc be "in transit" is there a way to check that?
Thanks again
It would still show in the wallet if the BTC was "in transit" and still unconfirmed. You said that you have a Transaction ID showing 33.96094 mBTC being transferred. Providing this Transaction ID may be helpful for diagnosing the issue. I would verify that the address the Transaction ID shows is listed on the addresses tab of Electrum. |

I have 34.07294 mBTC given me as a gift on BitcoinPaperWallet.com
I decrypted my Private key on bit2factor.com and entered a Sweep on Electrum
I have a Transaction ID showing 33.96094 mBTC have been transferred
How do I complete this Sweep and actually take possession of my BTC in my Electrum wallet
Thanks for any help!!
Sweeping to your wallet should be enough to transfer the funds to your Electrum wallet. As long as Electrum is fully synched, you should then see the bitcoins in your wallet. Are they not showing up for you? Is Electrum fully synched? |

The benefit of a paper wallet ( if properly generated offline ), is that your private keys remain offline in paper form and are not susceptible to viruses/malware or other forms of attack that could potentially compromise them if stored on a PC. However, with a paper wallet, you do have to ensure that you are storing them in a secure manner to prevent physical theft and other damage ( water damage for example ). You can use BIP32 to add a password to a paper wallet to help further secure it.

So how does me submitting my documents make it legitimate that I'm won't be abusing the system ? Or makes me a less of a system abuser? To sum it up,asking documents from online gamblers who believe in anonymity is bad.I don't support it. Not derailing this thread anymore...
Agreed, proof of identity doesn't make anything more legitimate. I would be opposed to any gambling sites that require documents/identity information. In the case of BitDice, I don't think that adding an email to your account can be compared to requiring documents/identifying information. You can always setup a new email address if you wanted to still remain anonymous while having an email associated with your account. |

I forgot to add later that day. I was experimenting with a public key linked to a wallet with around 0.2BTC and worked out that the public key gives you directaccess to the wallet to access the private keys from that (As I understand that the public key is generated from private keys so there may be a reversible component in that).
Anyway, thanks for the help! I'll definitely check out that link to see if there is any more information that I have missed.
(If I stated anythong wrong here and a user can spot it ten please do so - such as if I do or do not have access to my entire wallet from the public key especially).
You cannot derive the private key from the public keys and they aren't reversible, but Electrum stores both so you should be able to correlate them and lookup private keys for the public addresses ( at least you can via the desktop app). You should have access to all the keys and addresses in your wallet from the seed. That is the most critical part which can generate all the addresses and private keys for your wallet. |

Also consider encryption like TrueCrypt, something Snowden has mentioned.
Yeah, it might be better to use VeraCrypt though which is a fork of TrueCrypt and contains additional security patches since TrueCrypt is no longer under development. |

Is there a way to view the private keys, the pulic key and the addresses for electrum wallets for android directly from the app (no rooting).
Thank you in advance for the information! Also, if there isn't a way of getting this information, should I run the same wallet on desktop and android in order to access this information?
It looks like the status page has code to show the master_public_key as well as the seed as shown in: https://github.com/spesmilo/electrum/blob/master/gui/kivy/uix/ui_screens/status.kvIf this doesn't have what you need, you can always try to restore the seed shown into a desktop wallet which may reveal additional information. |

I was wondering if it is possible to use the get_unused_address functionality of a wallet from the commandline.
I was looking at the example to receive bitcoins on the website and based on this I wanted to see if I could create a donate link that would always show the latest unused address (i.e. after any donation, the next request on the webserver will automatically show the next unused bitcoin address).
I understand from the source that the addrequest command does this internally, but it will actually use up all the addresses within the gap every time you are calling addrequest.
Is it possible to call the get_unused_address from the commandline of electrum?
It doesn't seem like you can call get_unused_address via commandline from what I can tell. I checked and it doesn't look like you can issue that via JSONRPC either. However, you could issue it via the python console. Electrum recommends using addrequest to accept payments via a website so I wouldn't think there would be any negative side effects for doing it in that manner. |

I see around 40 people online when i log.
Is there any provision to hide our online status because by seeing the jackpot amount and frequency of dice rolls, I guess many gamblers would have opted not to show their online status. Is there any personal settings available for this, I checked twice still I am not sure about where and how to do. You cannot hide your online status, but you can hide your username from bets so that it shows 'hidden' instead of your username if you wish to be more anonymous. |

Yeah, the Ledger Nano S looks like a pretty good device. I think it is my favorite choice right now, but I was thinking of waiting for the Trezor 2 to come out so I could compare it with the Ledger Nano S before deciding which I liked best.

Are you guys using this API to find out whether to make a deposit instant or not? https://bitcoinfees.21.co/Currently it says the fastest and cheapest is 90 Sats/byte to get it confirmed within the hour? I don't think there are any other websites that have API data for bitcoin transaction fee times. Actually, I believe there are several other websites that offer APIs for fee estimations. BitGO for example has one at https://www.bitgo.com/api/#estimate-transaction-fees . I'm sure there is a couple of others that do the same as well. |

I found out you can decode it via electrum's console fairly easily as shown: >> import aes
>> from electrum import wallet
>> wallet.pw_decode('bBbGXH3ivbmwapRODeAn7wp7VviwDkpNOcaRdW9EDiA5xeYXj8CtrUidHvRbCubIJhMaPjlEOfO0kQM13RB6Zw==','125')
u'431a62f1c86555d3c45e5c4d9e10c8c7'
Let me know if this works for what you need. For further fun, here is how you get the seed words: >> import old_mnemonic
>> old_mnemonic.mn_encode('431a62f1c86555d3c45e5c4d9e10c8c7')
['constant', 'forest', 'adore', 'false', 'green', 'weave', 'stop', 'guy', 'fur', 'freeze', 'giggle', 'clock']
It's using the old_mnemonic as the seed is in the old format I believe. |
