It's as safe as you make it... it features AES256 encryption for the seed/keys and/or the entire wallet file itself... but if you choose to use a password like "password" or "abc123" then all the encryption in the world won't help you. Additionally, if you are a fan of downloading spyware/malware ridden apps/utilities and/or visiting "dodgy" websites... then any wallet will be bad.  |

I think you may need to update to v2.9.3... that seemed to fix a number of these "please wait" issues...
If updating is not possible, you might want to try this... Shut down Electrum... find your electrum data directory (~/.electrum on Linux I believe) and delete the "blockchain_headers" file and then start Electrum.

Though a new problem arises, I can't sign from the electrum wallet :/
That's because there is currently no "standard" solution for signing messages using SegWit addresses... so you can't sign messages using any SegWit wallet. Or are you talking about signing transactions?  |

NOTE: using wallets generated from BIP39 seeds longterm in Electrum is NOT recommended. The main reason for this is that you are unable to extract your "wallet words" should you lose the copy that you have. This is because Electrum does NOT store the actual wallet words in the wallet file like it does with Electrum generated (non BIP39) seeds. Instead, Electrum simply stores the "xprv" in the wallet file.
It would be wise to create a standard Electrum wallet with an Electrum generated seed... and move all your coins to that if you intend to use Electrum going forward.

I don't know who is low transaction fee wallet. If anybody know please explain.
Fees are not dictated by the wallet... in fact, a lot of (good) wallets will let you use "custom fees" where you can specify the exact fee rate you want to use. Wallets like Bitcoin Core, Electrum etc. Generally tho, these wallets will default to using fee rates that should get your transactions confirmed in a reasonable amount of time (hours). By purposely using "low" fees... you are likely to have to wait days. Recommended fees shown here: https://bitcoinfees.earn.com/https://btc.com/stats/unconfirmed-tx |

What's the recommended way to add applications to this distribution like Exodus while maintaining the integrity and not having to install the app every time you boot up ?
As far as I can tell, the only way to add applications is to download the bitkey source code, add them in yourself... and then compile it all https://github.com/bitkey/bitkeyYou can see how "Electrum" is installed here: https://github.com/bitkey/bitkey/blob/master/conf.d/electrumBasically, you'd just need to figure out how to add in the application installer, any required/missing dependencies, calculate all the appropriate checksums etc and then build the image. Not sure that this will qualify as "maintaining the integrity" tho  |

I have a trezor. The private key is on the trezor and along with the public key points to the location on the blockchain of my bitcoin? Yes/no
No. The "seed" is on the Trezor. The seed is used to generate all the private/public key pairs that give you control over certain bitcoins. on coinbase, my private key is stored by coinbase, has separate private and public keys and if I kept bitcoin there, yes/no
it would be in an entirely different location on the blockchain?
Yes. If your coins are in different addresses, with different private/public keys... they are separate from the coins controlled by the Trezor private/public keys. The seed is just a complicated as hell password that allows me to access the trezor, and the public and private keys? Yes/no
No. The "seed" is actually just a (VERY) large random number. The "seed mnemonic" (aka 24 words for Trezor) is a method to turn the "seed" number into a series of words that are a lot easier for humans to write down and store without making mistakes (it also includes a very basic checksum to help prevent errors). What the seed/seed mnemonic allow you to do, is easily recreate the entire wallet along with any address it has generated. Effectively, it is a complete "backup" of your wallet, in just 24 words that you can write down on a piece of paper and store securely offline. I can make a different seed (I don't actually want to) without affecting the public or private keys, or the location of my bitcoin on the blockchain? Yes/no
Depends what you mean by "affecting the public or private keys". If you create a different seed, it will generate a completely different wallet... with different private/public keys and addresses. Your bitcoins will continue to stay with your previous private/public keys and addresses, as your bitcoins will NOT move from their current private/public keys and addresses unless a transaction is created that moves them. So, if you created a different seed, without "backing up" your previous seed, you would lose access to the coins controlled by the previous seed... as your Trezor would now be using new private/public keys and addresses and have no access to your old ones. |

4- Hearing about an easy way to store bitcoin, I installed Electrum also on the same computer by creating a standard wallet (for some reason now I realised it is a multi-sig wallet, even though I am sure I did not create it this way)
When you installed Electrum, did it actually prompt you to select "Standard wallet", "Wallet with two factor authenticaion", "Multi-Signature wallet" or "watching only wallet"? Did you see something like this:  Or did it just immediately open up a wallet? NOTE: if you had selected "standard", it would have then prompted you to "create a seed", "I already have a seed", "use public or private keys" or "use a hardware device"... like this:  If it just opened up a wallet and showed you a blank transaction window etc, it is possible that you had already installed Electrum on your computer previously and created a default_wallet... when you uninstall Electrum it does NOT remove the old wallet files... so if you already had used Electrum before and then reinstalled Electrum, it would find and use your old default_wallet. However, if you definitely had the prompts, and clicked through the options... chances are that you did indeed create a Multi-Sig wallet... especially if the title bar says "2 of 2". If that is the case, then you need the two private keys that you used to create the Multi-Sig. Without those two private keys, you will never be able to get the coins out of the Multi-Sig. Did you perhaps use the private key from knots and the one from Bitcoin ABC? |

Hi, this is very good guidance. How can I sign a message so that I can prove a certain email belongs to me?
I don't think there is a way to do it to prove that you own an email address as such... signing only allows you to prove that you are in control of a private key/bitcoin address. sorry but i use exchanger wallet how can i get the private key ?
The simple answer is that (generally) you can not get the private key for addresses controlled by exchanges, thus you can not sign messages for exchange wallet addresses. Get a "proper" wallet where you can access the private keys |

It's actually pretty easy to recover BTC sent to BCH address (or BCH sent to BTC address), assuming you control the private keys for the address that the coins have been sent to... Unfortunately, with regards to the Ledger, the methods required for recovery will require that you use your wallet seed (there is not other way to get the private keys out)... this could potentially expose all the wallets you have created with that seed. Basically: 1. Goto: https://iancoleman.io/bip39/ and create an offline copy of it ("Offline Usage" instructions at bottom of page) 2. Using offline copy on offline computer, enter your seed as BIP39 Mnemonic 3. Select "BCH - Bitcoin Cash" as the "Coin" 4. All you addresses/private keys will be displayed at the bottom 5. Find the address you sent to, copy the matching private key 6. Either import or sweep that private key into the BTC wallet of your choice. Optional, but recommended: Create a completely new seed for your Ledger and send all your coins to the new wallets. |

This isn't really the place for computer hardware technical support  You might want to try the "Tom's Hardware" forums: http://www.tomshardware.com/forum/forum-30.htmlAnyway, according to the Asus page for that mobo, it supports up to 4x DIMMs, max of 64GB, so I don't see why it wouldn't work: Memory
4 x DIMM, Max. 64GB, DDR4 3866(O.C.)/3733(O.C.)/3600(O.C.)/3466(O.C.)/3400(O.C.)/3333(O.C.)/3300(O.C.)/3200(O.C.)/3000(O.C.)/2800(O.C.)/2666(O.C.)/2400/2133 MHz Non-ECC, Un-buffered Memory

They're claiming that the balances displayed on Blockchain.info (and other block explorers) don't show your account balance... I suspect this is because they're doing weird accounting and moving BTC around after they credit your account on their system. If you look at blockchain.info, you see: Total Balance (which is the sum of ALL Bitcoin that have ever been received to that address) and the Final Balance (which is what the CURRENT balance of the address is at this moment in time). "Your" address: 3EL14BoZCDXBmV65uCGAawXAZZxvnvZwN7 is currently showing: Total Balance = 0.11373723 BTC Final Balance = 0.10993723 BTCThat "Final Balance" is made up of 0.017 from this transaction and 0.09293823 from this transaction. Therefore, the amount in your wallet *should* be 0.10993723, unless CryptoPay is doing something retarded like re-using deposit addresses for multiple accounts and simply tracking payments using their own database, which I suspect is what is happening... as the funds that you sent to your Electrum wallet originally where sent from address: 36TEeqDrHnMFz9izKjgJipquvooJ7iTDa7 in this transaction... so I'm guessing that you cannot rely on the balances that are being displayed by blockchain.info for your deposit addresses, as CryptoPay are doing weird, confusing things. At the end of the day... I still think you are chasing the wrong thing... you sent coins from CryptoPay to Electrum, they showed up in Electrum wallet... and then they got sent from Electrum wallet somewhere else... so it would appear they have been stolen due to your Electrum wallet being compromised, not lost within CryptoPay's weird accounting system. |

Thank you very much now it actually resets to the correct sub-balance 1rst bet, but it doesnt go to the 3rd sub-balance. I want it every 3 losing streak to go to the next balance! What i have made seems to be that i have to have 6 losing streeak to go to the 3rd sub-balance! Any ideas?
So you're saying that if you are on 2nd sub-balance... and you get a win... it should still stay on 2nd sub-balance and "keep betting 0.00000080 until profit is 0.00001000" right? If so, you'll probably need to use a boolean flag to keep track of which sub-balance you are betting on... so you can put another if statement inside the "if currentstreak==-3 then" block, so that it will work when you have a streak of 3 losses... I'm not sure it'll work properly with the 3rd sub-balance, after 1 win, I think it will reset to 0.00000008 and start again... but you get the idea I've made some changes to chilly's script... added in "balance2" flag... I think it should be close to what you are after, but do bear in mind, this is completely untested!
chance=49.5 --sets your chance for placing a bet
nextbet=0.00000008 --sets your first bet.
basebet=0.00000008 -- moved to only set once
currentbase = basebet -- save the current base bet
balance2 = false -- flag to indicate we are using 2nd sub-balance
function dobet()
if profit > 0.00001000 then
resetstats()
currentbase = basebet -- reset to base bet
balance2 = false -- made our profit, reset to 1st sub-balance
end
if win then
if balance2 == false then
nextbet=currentbase -- reset to the current base
else
-- using 2nd sub-balance, start from 0.0000080 until profit > 0.00001000
nextbet=0.00000080
end
else
nextbet=previousbet*2.54
end
if currentstreak==-3 then
if balance2 == false then
balance2 = true
nextbet=0.00000080
currentbase = nextbet -- save current base
else
--already betting 2nd sub-balance, move to 3rd sub-balance
nextbet = 0.00000800
currentbase = nextbet -- save current base
end
end
if currentstreak==-10 then
nextbet=0.00000001
end
end end

Do anyone have a dicebot script which can help me built some balance from just a faucet claim?
.. or is it recommended to have a certain amount of funds before running the bot generally ?
Honestly, I don't know why people bother trying to build from a faucet claim using scripts... your best bet (#excuseThePun), is to just grind it out doing 99x payout bets with the max faucet... eventually, you'll hit it and you'll finally have a decent balance to try and play with. For added grind/payoff, try 999x |

I am getting a new phone and was wondering how to move the 2fa to the new device. Will I need to restore the wallet, disable 2fa and then again enable? If so, will I need to pay again for the 2fa service?
That depends on what app you use for Google Authenticator... I use Authenticator Plus, it allows you to backup and restore all your "secret keys", so you can migrate to a new phone without issue. I'm not sure what backup options the "original" Google Authenticator app has... It was one of the reasons I started using Authenticator Plus... You might also want to check out "Authy"... I've heard good reviews about that. "Disabling" the 2FA wallet by restoring from seed DOES NOT disabled the 2FA secret in Google Authenticator... and when you restore and select "keep" it'll ask for the old code or make you reset it... so it *should* be OK... I'd highly recommend attempting to setup the new phone BEFORE you dispose of the old one so you can test it is OK. |

HitBtc is in top 10 biggest exchange right now. So i think 100% ours coin secure there.
Just like the way the coins were secure in Mt. Gox when it was Top #1 Biggest exchange?  One of the single most important concepts in CryptoCurrency... if you don't have sole possession of (and control over) the private keys... you don't have any coins. It's as simple as that. You put them on an exchange, you are literally trusting strangers with your money. |

Are you using Bitcoin Core? If so, goto "Settings -> options -> Wallet" and tick the "Enable Coin Control Features" box. Then on the "Send" window, click the "inputs" button and then select ALL the inputs except the two that you don't want. You will then be able to send all your coins (except the two inputs you no longer want) to a new address. Perhaps you should even go so far as to create a whole new wallet, so you don't have to worry about those coins ever causing you issues again?
If you're not using Bitcoin Core, does your wallet have "Coin Control" features? I know Electrum does... not sure about other wallets. Electrum even allows you to "freeze" addresses, so you can freeze the address the 1 satoshi inputs are on and that will guarantee that they never get used when sending transactions.

"Confirmations" are simply the number of blocks that have been mined since the transaction was put into a block... the block it is put in, counts as 1 confirmation. The formula is:
Number of Confirmations = (current blockchain height - block height it was confirmed in) + 1
For example, your transaction is included in block# 492400... it now has 1 confirmation. 10 blocks later, at block# 492410, it will now have 11 confirmations... 10 blocks after that, at block# 492420, it will have 21 confirmations.
So... if you transaction was in block# 492400... and the current blockheight is 492502... # confirmations = (492502 - 492400) + 1 = 103 confirmations.

Does the "transaction.get" method give you the block# or height that it was confirmed in within the hex data? If so, then you could just calculate the difference between that number and the current blockchain height and that is your number of confirmations.
NOTE: I see the Address.get_history method returns block heights for the transactions associated with an address... maybe that's an option?

Glad you got it sorted mate... hopefully things go a bit smoother in the future
