If you just look at the git repo of electrum server, you'll immediately see following text, completely answering your question:

As for a tutorial: same answer, there is an easy step-by-step guide right on electrumx's git repo

For the truely lazy, there even seems to be an installer, directly linked from the first page of electrumx's repo:

hm, that's an altcoin... It might be best if you would close the topic, and re-ask your question in the vertcoin ann thread, that way the vertcoin dev's could help you out.

After googeling for a bit, i don't think vertcoin core is HD, this means that i don't think it's a deterministic wallet, so i don't know what you have saved, but i doubt it's a seed...
I can be wrong tough, that's why it might be wise to re-ask your question in the vertcoin ann thread.

Using recuva on your old harddisk is still a good thing to try, wether i'm wrong about the fact that the wallet is not deterministic or not... But please do understand that the more you use the harddisk, the smaller the chance recuva will be able to recover your wallet.dat!

Just a last couple of questsion about your seed:
- when were you shown the seed? During the first wallet installation, or did you have to take extra steps?
- how many words does the seed consist of?
- if it's just one word, what's the seed's lenght, and which letter does it start with? (tip: if it's one word, it's not a seed)

Which wallet did you use? There are dozens of different wallets, each have their own wizards...

bitcoin mixers are real... you don't get new coins, you just break the link between your old and your new coins... However, i haven't used grams in the past, but i do know there are many scam sites that impersonate helix grams... I have no idear if this is the real link,  or a link to a scam version

Ai... Een online wallet...
Ik denk dat je best even contact op kan nemen met hun support dept. Ik ben niet 100% zeker, maar ik denk dat zijn een unconfirmed tx gewoon blijven rebroadcasten, dus op die manier geraakt je probleem nooit opgelost (disclaimer: ik gebruik geen online wallets, dus ben niet 100% zeker).

Ik zou je aanraden om, eens dit probleem werd opgelost, over te schakelen naar een desktop of hardware wallet... Op die manier ben je de enige die je private keys kan beheren, en heb je meer opties als er iets moest mislopen, en minder risico's (zolang je pc maar virus en malwarevrij is)

I've used recuva when recovering a disk with my previous job... It did the trick.

Zonder transactieid is het vrij moeilijk om goeie raad te geven... Als je transactie een fee heeft van meer dan 10 satoshi/byte is er een mogelijkheid om transacties aan te melden bij een mining pool die deze dan prioriteit geeft... Zoniet zijn er nog wel wat andere dingen die je kan proberen. Zonder transactieid is het echter moeilijk om hier verder op in te gaan.

Als je wil dat je transactie door je wallet vergeten word, zodat je de unspent output kan gebruiken in een nieuwe transactie met hogere fee zijn er 2 mogelijkheden vanuit bitcoin core:
1) ga naar help, debug, console, en voer volgend commando uit: "abandontransaction [txid]"
ALS dit niet werkt, gebruik dan optie 2:
2) sluit bitcoin core (bitcoind of bitcoin-qt) af, ga naar de console en voer uit: "bitcoin-qt -zapwallettxes" of "bitcoind -zapwallettxes". Dit kan zowel op een linux, mac als windows box, zolang bitcoind of bitcoin-qt maar in je path zit... Zoniet zal je moeten zorgen dat je in de correcte working dir zit waarin deze binaries staan.
Hierna zal er een rescan gebeuren, en alle niet-geconfirmeerde transacties zullen door jouw wallet "vergeten" worden. Weet wel: als je transactie voldoende gepropageerd werd door het netwerk, kunnen er nodes zijn waar je tx nog steeds in de mempool zit... Er is dus een (kleine) kans dat de tx nog steeds in een valid block terecht komt!


Ja en nee... Sommige wallets broadcasten een tx maar 1x. Andere blijven je tx broadcasten. In het eerste geval zal een unconfirmed tx uit de mempool van de MEESTE nodes gegooid worden na ~3 dagen. Als genoeg nodes jou transactie vergeten zijn, zullen sommige wallets doen alsof de tx nooit gemaakt werd. Anderen hebben een extra stap nodig om de tx niet meer te broadcasten en/of te vergeten.

In that case you can just use your seed to restore your wallet... You'll lose any labels attached to your history, but that's about it...
I'd still suggest to turn off your computer and use a second (clean) device to restore your wallet, just in case the seed is wrong and you need to scan your HD for the wallet file.

I bolded a common mistake: the era where you could mine bitcoin using your CPU or GPU has long gone...
Mining is still a viable way to earn some BTC, BUT you need a very good electricity price, a good plan, a good location, enough startup capital and a lot of luck.

I didn't re-do your calculations, but 700€/month is might be possible at the current BTC price and difficulty
However, before jumping in, you need to realise the following things:

• If the BTC price drops, so does your profit
• If the diff rises (more miners enter the network), your profit plummets
• If your antminer breaks after the 90 days limited warrantee period, you're scr*wed (and those things seem to break quite easily). Even if it breaks within the first 90 days, you need to realise that chinese warrantee isn't the same kind of warrantee we're used to in western countrys
• If you live in the EU, do know there usually are rather big custom's charges when importing ASIC's
• Most recent ASIC's are loud, and produce a lot of heat

So, bottom line, expect to pay more for your antminer than the price that is advertised on the seller's webpage (and a lot of those resellers turn out to be scams to, so be carefull). And once you're running your ASIC, prepare to see your profits going down a lot faster than you anticipated...
If, for some reason, you have calculated all these odds, and you still think it's a good idear: sure... why not... give it a try

Sorry to be the barer of bad news... But if you entered your private key on a phising website, and they used your key to spend your ETH and fund their own addresses, you've lost your ETH as soon as those transactions were confirmed.
No way of getting it back...

Best you can do is keep tracking the thief's addressess, crosslink them against any social media you can find (see if he posts one of those addresses) and hopefully one day law enforcement might find him (potentially by accident), and you can start a lawsuit against this person to get your funds back.
A different route is to try to contact his domain registrar and hosting provider... Maybe they have his name on file...

First of all: stop using your pc... Shut it down, turn it off... revisit the forum using a different pc or a mobile device.
Second step: clone your disk... boot from a linux usb and use gnome-diskutils or dd
Thirth step: use a recovery tool to scan your disk, and hope it can recover your wallet.dat.

Other than that, odolvlobo is right: if you don't have a backup of either your wallet.dat or the seed, you've lost your BTC...

I missed this hour's ViaBTC slot (tried to submit your tx @ 9:00:15, so the 100 slots were filled in less than 15 seconds). I'll try again next hour. I'll edit this post if i succeed in accelerating your transaction.

EDIT: ViaBTC accepted your transaction It should be included in one of the next blocks mined by viaBTC (this can take a couple of hours, but from now on, you'll be in viaBTC's blocks)

I'll push it to viaBTC in 23 minutes (at least, i'll try to push it to ViaBTC, their quota is usually met in a matter of seconds). Since it has 17 sat/byte, viaBTC *should* accept it.

This is a common misconception. The fee is not based on the transferred value, it's only dependant on the size of the transaction (in bytes).
The size of the transaction only depends on the number of inputs and outputs, not their value.

Manually calculating a fee is something that's better left to more experienced users (imho), i'd suggest picking a good, decent wallet and following it's advice regarding fees. If you have no clue about inputs and outputs, don't try to pick your own fee, cause you'll end up in the situation where you payed 0.005 BTC as a fee for a 0.05 BTC transaction, and honestly believe the fee *has* to be sufficient... But that's not how it works i'm afraid...



I have submitted it to antpool, but i don't think a 1 sat/byte transaction will have a decent chance with them either... ViaBTC doesn't accept a 1 sat/byte tx

Other options:

I've tried to give feedback/answer the 5 questions:

correct

Bitcoins aren't something physical, they are not stored on your pc. If you "own" bitcoins, it basically means you have access to the private key that can be used to create a signature for one or more unspent outputs that funded the address that was created by hashing the public key belonging to the private key in question.
In very simple wording: your bitcoins are just lines in blocks that are stored on thousands of computers. Importing or exporting private keys doesn't change anything (unless you use an unsafe procedure/PC and your private keys get exposed, in this case you might get robbed)
So, dumping the private key will not "destroy" your bitcoins.
dumpprivkey only dumps one private key to stdout. If you need to dump all private keys, you can use dumpwallet (dumpwallet actually takes a parameters in which you can define the file that will be used to dump all keys to)


open the debug window => importprivkey --privatekey--
This procedure will rescan the blocks on your disk, importprivkey takes an optional argument that will avoid this rescan (if you want to)


I've never used this, but apparently it's used to import multiple private keys at once

I have a hard time understanding this question. IF you use a decent wallet, it will guide you trough the process of creating a transaction spending one or more of the unspent outputs controlled by you. A decent wallet will make sure it funds the address of whoever you're sending BTC to, and it will make sure the change is being used to fund a change address.
Only if you manually create a raw transaction, or if you use a newbie-unfriendly, bad, wallet, or if you start messing with options you don't understand, you might end up losing your funds.

There aren't that many litecoin desktop wallet's (AFAIK, i don't hold many LTC's). Since it has a .dat extention, my first instinct would be to re-try litecoin core... Maybe you could post the last couple dozen lines of your debug.log, or just move the debug.log, try to open the client using the litcoin.dat as wallet file (so a new debug.log gets generated), close the client again, then upload the full debug.log, so we can have a look at what's happening.

Another usefull tool is db_dump, this tool allows you to dump berkeley db files, altough encryption might mess up the end result...

Just in case you're running linux, it might also be good to try the command "file litecoin.dat". At least it will tell us what kind of file we're dealing with.

My advice would be to
1) update your "LINX" wallet
2) either download bitcoin core, electrum or buy a cheap hardware wallet
3) move your funds from "LINX" to core, electrum or your hardware wallet

Eventough, you bitcoins can never "evaporate", it's still possible that this (to me unknown) wallet uses some kind of encryption or derivation scheme to encrypt or derive private keys, and when you don't update, you might not be able to manage our unspent outputs anymore.
An other possibility is that it's a centrally managed SPV wallet, if the central servers go down, you might have problems spending your funds.

These are only 2 theory's, i don't know "LINX", so i have no idear how they work, but if they tell you you have to update your wallet, i would take it very serious (seriously: consider moving to a trusted wallet)..

First of all: there's a middle ground here... Online wallets are insecure (imho), you're not the (only) one controlling your private keys, so you're not the (only) one controlling your funds.

If you're not ready to buy a hardware wallet, a desktop wallet on a clean PC will usually be a step up (safety wise) compared to an online wallet.

As for your question: if you can export your private keys from your online wallet, you can probably import them in the fork's reference wallet... However: this might not always be a good idear, for example, not all forks might have replay protection, so importing your private keys into the fork's wallet and spending those forked altcoins might end up costing you your unspent outputs on the bitcoin network!

like i said in the post right above yours: a $4 fee might be perfectly fine for one transaction, grossly overpaying for a second transaction and not nearly high enough for a thirth transaction... Even if you are sending the same value of BTC, the necessary fee might be completely different.
$4 says nothing... You need to tell us:
1) how many inputs your transaction had
2) how many outputs your transaction had
3) if you were using a segwit wallet

 FIAT numbers are not to the point.
