What Are the Differences of the 4 Electrum Wallets Types?
I guess there is some modality difference that I can use for security and utility purposes? Sound great, but I can't find the cliff notes so to speak on youtube.
With 4 types, do you mean "standard wallet", "wallet with two-factor authentication", "multi-signature wallet" and "watch bitcoin addresses"? If so: Standard wallet = normal, standard wallet... Optional encryption, can be HD (either using a seed phrase or a hardware wallet), or it can be non-hd by importing private keys wallet with two-factor authentication = wallet with two-factor authentication, it uses a thirth party to perform the 2FA, the thirth party charges a service fee multi-signature wallet = multi-signature wallet, you can pick how many signatures (optional/required) watch bitcoin addresses = watch addresses for new unspent outputs.. You don't need the private key, you won't be able to spent. |

Without knowing any of the addresses, then it is going to be problematic to determine whether or not you have found the correct seed, as you have nothing to test against.
If the OP's wallet cointains sufficient BTC, it might be worth setting up a bitcore node with full addressindex. That way you can rip trough the ~40k seed phrases (only keep the valid ones if the last word is a checksum), generate the xprv, derive the first 100 addresses and the first 100 change addresses and check them for any activity... Since bitcore with all those indexes turns on takes a couple weeks to fully sync, and the script will probably only be able to test a couple phrases a second (untested, but since the script has to iterate to the next variation, generate an xprv, derive 200 addresses, use a json-rpc query, parse the results => i don't think you'll be able to process hundreds of iterations a second), this would take several weeks to brute-force, but if the incentive is big enough, it might still be worth it. |

I'm new to cryptocurrency without knowledge about technical. I heard so much about node but I don't know node what it is. What's purpose of node in Bitcoin network and why we need it ? What's the different between node and Masternode ??
Instead of re-writing these answers, i just found 2 nice explanations for you: to answer your first question, this was the first hit in google: http://www.coindesk.com/bitcoin-nodes-need/As for your second question: bitcoin doesn't use the masternode concept. I think masternodes were invented by dash, here's a link: http://dashmasternode.org/what-is-a-masternode/ |

wat voor meer info heeft uw nodig. dit is de bestand naam hoe hij is opgeslagen bitcoin-wallet-keys-2014-01-23
Ik doe een gok hier, maar die filename lijkt me sterk op de backupfile van schildenbach wallet for android. Zou het kunnen dat je in 2014 een bitcoin wallet op je android toestel had staan? Je kan het volgende eventeel proberen op een KOPIE van de file https://github.com/bitcoin-wallet/bitcoin-wallet/blob/master/wallet/README.recover.mdAls dit niet werkt, kan je een proberen om een kopie open te doen met een text editor en eens te kijken wat er zoal in de file staat... Misschien zijn het keys, misschien is het een xml or een json bestand, misschien is het binair... Deze info zou handig zijn. Dit stond in de backup mail. meschien ook nog wel goede info ik heb dr de ballen verstand van en mijn engels werkt ook niet echt super mee  :P The attached encrypted file contains Bitcoin private keys and should be kept safe at all times. Don't forget the encryption password! https://play.google.com/store/apps/details?id=de.schildbach.wallethttps://github.com/schildbach/bitcoin-walletAls die links er ook instonden, was mijn gok correct  Als je nog een android toestel hebt, kan je proberen om die schildbach wallet te installeren, en een copy van die backup te restoren. Als dat niet werkt kan je altijd eens proberen om de procedure uit m'n vorige post uit te voeren. Als dit niet lukt raad ik je aan om iemand betrouwbaar te zoeken die je met de procedure kan helpen (lieft iemand die je in't echt kent, zoniet iemand betrouwbaar op dit forum: lieft iemand met veel groene "trust" naast z'n naam) |

Hello, What's more worth it to mine with right now? Antminers or GPUs. The difficulty keeps rising and I dont know what to choose  Thanks ! You are in the bitcoin mining subforum, so i'm going to give you a bitcoin mining answer: Mining with your GPU will make about $0.5 worth of BTC a year, if you have a decent GPU that runs 24/7. An S9 will make you about $5000 worth of BTC a year... Offcourse, after you pay for power and hardware, your profit will be very negative for the GPU, and *might* be positive with the S9 (depending on your electricity rate, your luck, the diff rise, the price fluctuations,...). If you're asking about altcoin mining, it might be best to re-ask your question in the altcoin mining subforum. If you want an estimation what each bitcoin ASIC will produce at current diff, block reward and BTC price, you can find the ASIC's specs here: https://en.bitcoin.it/wiki/Mining_hardware_comparisonAnd you can plug those values in a mining calculator like this one: https://www.coinwarz.com/calculators/bitcoin-mining-calculator |

quoted, will verify and then edit this post EDIT: couldn't verify the message with my own tool nor electrum 2.8.2... Is there something strange going on with the newline characters? Maybe try a message without newlines? |

Acutally it's very strange. I noticed 1 confirmation at the beginning. But then the 1 confirmation was gone. What happened? Things start to make sense: https://blockchain.info/block-index/1521268The transaction was included in a block, but it was orphaned  I don't think it'll hurt if you try to rebroadcast the transaction... Just to be sure (unless you're planning on waiting untill the unconfirmed transaction drops from the mempool of most nodes) |

Transaction fees depends on the time of the transaction you want. You can also pay a fees of 0.0001 btc to any desired fees you want. Paying higher fees will immediately give you the confirmation. Bitcoin will quickly appear on the desired wallet/bitcoin address sooner if you are paying high fees. But now-a-days many people are facing problem like paying high fees and still are not getting confirmation on huge transactions. I hope the issue will be solved sooner. But for now you can try paying high fees to get quicker confirmation on transactions.
I would not advise anybody to pay a fee of 0.0001 BTC. Using fixed fees is a thing of the past, and will result in either getting your transaction stuck or in grossly overpaying sooner or later. I would also like to notice there is no fee that will result in an instant confirmation... The fee is something you give to the miner as an incentive to add your transaction to the block he's currently solving. There is an average of 10 minutes between two blocks, so even if you'd add 1000 satoshi's per byte, you'd still have to wait an average of +5 minutes before you get into a block... Lastly i would like to add that it doesn't matter how much fees you add, the transaction gets broadcasted around the network in a matter of seconds. So indeed, after a few seconds, about any* transaction will show up as "unconfirmed" in most wallets... However, a sufficient fee will make sure it ends up in a block in a reasonable timeframe. * unless there is something wrong with your transaction, like double spending the unconfirmed input, unconfirmed parents, dust outputs,... |

currently the fee is around 2usd for priority, there is a ICO that I want to participate in, if I pay 10usd as fee I get first in line in mined block to guarantee participation?
is there any disadvantage with having 10usd fee, maybe the transaction get cancelled?
any difference playing 2usd fee, 10usd fee, 100usd fee?
the biggest fee gets first into the mined block?
Usually, yes, the more satoshi's per byte you add, the higher the chance a miner will pick your transaction above the other transactions in the mempool. However, it's completely up to the miner. If the very next block gets mined by a miner that choses only to include the coinbase transaction, your transaction won't be added... If the next block is mined by a miner that decided to fill the block he's working on with spam transactions, you're also straight out of luck. However, generally speaking, if you outbid the other transactions in the mempool, you have a really big chance of getting into the very next block. There is no "downside" for using "to high" fees... Exept the fact that you'll pay more fees (obviously) That being said: there are two more things i wanted to tell you 1) there is no need to outbid 100% of the waiting transactions in the mempool... Study https://bitcoinfees.21.co/ for more info, but what i mean to say is: if you pay enough to be in the top 1Mb of waiting transactions, you'll probably get into the next block. 2) be carefull: fees are not calculated per transaction or per amount of BTC transferred, but they are calculated based on the transaction size. This size depends on the number of inputs and outputs... You can use my tool to guide you in picking a good fee: https://www.mocacinno.com/page/feeestimate or you can rely on the fee estimation of a DECENT wallet... |

ASIC Miners consume huge electricity,so to run this device you will spend a lot on electricity and cooling. If to calculate total expenditure is it profitable anyway?
Depends mostly (but not only) on your electricity rate... If you have an S9 and pay 2-3 cents/Kwu, you can easily break even. If you have an S1 and you pay 30 cents/Kwu you're losing money for every second you're mining... |

I realise most of these answers were already given in one way or another, but since i see you're making some mistakes here, i'd like to repeat them and chose my own wording: I'm new to this bitcoin stuff and that, I'm currently mining in the cloud, since I do not have equipment to mine, asics not much less gpu, I just have pentium 4, 1 gb of video and 2 of ram, practically one Basic pc, I want you to solve me several doubts:
1) You were correct, you cannot mine with a cpu. You might be able to mine some altcoins using your GPU, altough i would seriously doubt you would have invested in a decent GPU if i see the rest of your desktop's stats 2) stop right there, 99% of the cloud mining companies are scams, the rest sells you 100% of the risks for a very small cut in the profits. 1) Best wallet to store different types of coins (doge, dash, btc, litecoins, etc.) currently use yobit
Stop right there (again), stay away from online wallets and exchanges... Go for decent desktop wallets! They general rule is: if you're not the (only) one in controll of your private keys, you're not in controll of your funds... If the exchange/online wallet blocks you, gets hacked, runs away,... you're left with nothing. 2) If I mino another type of currency, an example: I start to mine dogecoins, can be sold directly or have to exchange for btc to then sell them
In my experience, you get the best deal if you look around at all different exchanges exchanging the coins you want to exchange (wow, 3 exchanges in one sentence). Take into account that different exchanges have different fee structures! 3) in the pages that I am currently mining I have the option for btc, dogecoin, dash, etherum, litecoins and even the same GH / S, my question is which is these coins is better to mine or is it preferable to mine a quantity of gh / s To be able to make more coins per hour / day / week / etc
If it's cloud mining, you'd be better off getting the hell out of their system. 4) 6) If I get 'X' amount of any currency, it is better to invest it on the same page or directly take it out to my wallet.
My advice: if you're talking about cloudmining: withdraw as much as you can, don't look back! certainly don't re-invest |

Hey allemaal,
Ik hen een vraagje ik was helemaal vergeten dat ik bitoins had.
Deze heb ik gisteren weer gevonden had en backup gemaakt en die staat in mijn mail.
maar de vraag hoe kan ik de wallet weer terug zetten. De backup is uit 2014 weet niet meer welke wallet.
ik heb bitecoin core als wallet heb ik nu gedownload. wat kan en moet ik nu doen?? help my
Wel, Als je een wallet.dat hebt is de kans reeel dat je in het verleden ook bitcoin core gebruikte. In dit geval kan je gewoon je huidige bitcoin core even stoppen, naar de data directory gaan, je huidige wallet even hernoemen (bijvoorbeeld wallet_nieuw.dat), een copy van de oude wallet.dat in de data directory pompen en je core wallet opnieuw opstarten. Deze zal dan de blocks opnieuw scannen, daarna zou je de unspent outputs moeten kunnen gebruiken om nieuwe transacties te maken. De data directory voor linux is ~/.bitcoin, voor windows vind je deze wel ergens in de wiki (ben te lui om er zelf achter te zoeken) Je kan in de toekomst beide wallets gebruiken (je huidige wallet, en de backup van je oude wallet) door bitcoin core te starten met de juiste opties (de wallet welke hij moet gebruiken is een optionele parameter, als je deze niet ingeeft gebruikt hij ~/.bitcoin/wallet.dat). Als deze procedure niet werkt is je wallet backup waarschijnlijk geen bitcoin core wallet.dat. In dit geval hebben we idd wat meer achtergrondinformatie nodig |

I need a loan of 0.00003 BTC, have nothing to give in a pledge. Maybe someone will do it At this very moment, the optimal fee is 360 sat/byte. for an average transaction this comes down to ~81.000 satoshi's ( https://bitcoinfees.21.co/). You ask for a loan of 3000 satoshi's...  The fee a lender would need to pay for a speedy confirmation would be 27 times the loaned amount... If somebody would "lend" you 3000 satoshi's, there would be no way you could ever spend that input (since the fee needed to spend those 3000 sat would be 81.000 sat) I strongly discourage users from using faucets (they're a waste of time), but in your case i'd make an exeption |

Which one do you prefer?
Personally, i prefer a hardware wallet... Both your choices are ok, but they have a different use case: - a paper wallet can be used to deposit BTC without withdrawing... It's cheap and easy to make, but once you sweep it, you have to make a brand new one. - cold storage (i assume you mean using an airgapped pc) is more expensive (since you need a dedicated offline pc), but it can be used to deposit and withdraw A hardware wallet almost offers the security of an airgapped PC, but is much cheaper... |

Hello,
The good news is that I still remember the clues about the secondary password of my wallet
I am willing to provide all the information about the wallet for you, but I am afraid when you successfully decode you will get my bitcoin.
Currently I have 1 more case containing 7 BTCs, and it also has forgotten secondary password. It's heartbreaking to log in to Wallet successfully, seeing that the bitcoin is still intact and unusable.
At this time I need more help than ever ...
I am willing to give you $ 500 for you to help me install, but the btcrecover install phase is too difficult for a technically poor person like me, is there a way to do it the simplest way!
I don't think there is an easyer way than using btcrecover. I completely understand not willing to send an encrypted wallet to me (i wouldn't send any wallet to anybody ever). Maybe you can PM : https://bitcointalk.org/index.php?action=profile;u=130960 ? He has a history of cracking wallets, and has more trust than i do... |

How long does it take to decipher the wallet? Why do not you get all the wallet information from me and decode it?
I already answered this question The first question (How long does it take to decipher the wallet?) answer: basically it's impossible to tell... It depends on how much input you can give about the possible passwords... If you chose a random 12 letter password and the only thing you can tell me is it contained the letter 'E', i won't even start bruteforcing it... I'd just tell you to concider the 2 BTC as lost. On the other hand, if you chose a 5-7 letter password and you're certain it contained the name of your dog, the first letter of your girlfriends last name and did not contain any special character, it'll probably be cracked in a very short time... The second question (Why do not you get all the wallet information from me and decode it?) If i can crack the file on my own machine and take $500 if i succeed, then send the remaining funds to an address of your choice, the risk becomes (much) smaller, but i don't know if i'm trusted enough to send a wallet file to... My advise in this case would be to search a really, really, really trusted person to give you encrypted wallet + password info to.
I'd still be willing to do this, but you do have to understand that you're sending a wallet + password hints to somebody that has no green trust, and has no record of handling other people's money |

How many ways to step with each steps, each steps is 100 $, I will be back to the BTC of your steps per 1, If you have to plan 5 steps to be btcrecover. Please help me, I need real help and not deceive anyone. The effort you put into it will be worth it  It's not the reward that's the problem, nor the amount of steps... It's the fact the reward is "not in hand" (or: not in the hand of a person i more or less trust). It doesn't matter how you put it, i won't invest hours of work writing a guide that can be followed by someone without any experience without knowing the bounty is either in my wallet, or in the wallet from somebody i trust (aka, an escrow provider). Don't take this personal, i've just been burnt so many times already i no longer find a promise sufficient "collateral" These are the steps i would include in a guide, complete with screenshots and copy/pastable text: 1) prepare your OS, install the dependancies 2) make sure btcrecover runs (run tests) 3) make sure we have your (encrypted) wallet, potentially using a tool to create it starting from your ID 4) create the token file 5) run btcrecover |
