In your case? Just stop using this account and create a new one with any username you want...

Why? Because there are only 2 ways of changing your nick:

1) become a VIP donator by donating 50 BTC. VIP's can change their nick

2) by asking the admin... However, this forum has over one million accounts, the admin gets swamped with many requests on a daily basis, so the chances are slim to none he'll grant a nick change... Saving your post history of 9 posts is hardly worth his time

if you edit your bitcoin.conf and add "daemon=1", you don't have to start it with the -daemon option

EDIT: found this nice link with other potential ways to do this: https://bitcoin.stackexchange.com/questions/13795/ubuntu-linux-how-do-i-start-bitcoind-as-a-service-to-run-automatically

EDIT2: removed the notion of the inittab, does not apply to ubuntu

Your transaction has been included by antpool... It has 9 confirmations now.
Maybe it would be best to lock the topic now, otherwise you'll probably get 10 other guys stating it has been confirmed... It clogs up the forum.

Ah, so you don't want to post the psd, but an image to create an ann thread... In this case, yes, you have to convert the PSD to jpg/png/gif and use one of the hotlink image hosting sites to host your image...

imgur seems to be pretty popular, but there are others out there to...

I always used toencrypt my data with 7zip (using a strong password), then upload it to filedropper (or a similar service). Then just PM the link + the decryption password.

Are you sure armory is completely synced? AFAIK, it also has to finish scanning the transaction history (i don't have an armory installation to verify this anymore since my company switched our HD's to SSD, so i don't have enough space for armory)...
Also, if you'd post the txid, that would help us figure out if the transaction was broadcasted/confirmed.

@jackg and @aleksej996,

you're both right, but i already gave the OP a link to my site explaining both RBF and CPFP (it even has a wizard to create a raw, unsigned CPFP tx, and a tx doublespending the inputs of the unconfirmed tx). The OP indicated he found this way to complex to follow, so this does not seem to be an option for the OP.


@OP:
I just accelerated your transaction, however, this only means it now has a higher priority in the antpool's mempool. It will still have to wait untill all other higher priority transactions were included into the blockchain. Because of the 2 sat/byte fee, you can expect your transaction to be the lowest priority transaction of the high priority transactions, so it can still take hours/days before it gets confirmed.
Next time you have to use a decent fee!

There are several ways to solve this problem.
A long time ago, i wrote a wizard to help you with stuck transactions, near the bottom of this page you can find your options:

I also have access to antpool's transaction prioritiser (i hope it still works). If you can't figure out how to solve your problem by tomorrow morning, i'll try to push it to antpool (i'm just about to leave the office right now, so i can't push your transaction right now)

1) how to recover your account?

• make sure you have a wallet that allows you to sign messages
• Create a message (doesn't matter which one) and sign it with an address belonging to your wallet
• Post the message, signature and address in this thread
• Make sure somebody quotes your message
• In case your account does get hacked, follow the thread posted by ikilledcobain

you can use any address in any unedited post to sign a message, but the thread above is more convenient, since all staked addresses can be found in one thread, and all messages get quoted (the quoted text cannot be removed by a hacker, since he doesn't own the account quoting your message)

2) make a cool signatures

• If you mean: make a cool address to sign messages with, you can use vanitygen
• If you actually mean the signature itself: allmost impossible, the signature depends on the text that is being signed. You would need to add a nonce to your text, then iterate the nonce and always create a signature in order to "brute force" a cool signature...
• If you mean the text being signed: you can pick whatever text you want, you can allways sign it...

a LOT of misinformation is being spread in this thread... Here's my effort to give a newbie-friendly explanation of most of the topics discussed so far.

A word of caution: i tried to be newbie-friendly, so i "dumbed down" several facts. So, read my post and take it as a starting point in your jouney to learn about bitcoin mining.

In order to send and receive bitcoin, you have to create transactions. A transaction is basically a signed piece of text that says:

It's a little bit more complex than that, but basically, this is a transaction.
A transaction has a certain size (in bytes) and is broadcasted around the network. At this point, the transaction is just stored in the memory of the nodes. After a couple of days, or when the node reboots, the unconfirmed transaction is lost. If most of the nodes forget about your transaction, it's like it never happens.

This is why miners collect unconfirmed transactions and put them into a block. A block used to contain up to 1Mb of transactions. At this moment, there's something called segwit that moves part of the transaction into a different part of the block, resulting in more transactions fitting into a block (but that's a complex, different topic). Every transaction pays a fee (the difference between the inputs and the outputs). A miner is allowed to add one transaction whose outputs can be spent by an address of his choice, and fund this address with 12.5 BTC + the sum of all fees of the transactions in said block.

The block that exists in the miner's memory is not automatically valid. If a miner could just fill blocks with transactions and broadcast them to the network right away, anybody could create a blockchain of infinite length in a short amount of time, and there would be chaos.
The design of bitcoin is aimed at producing one block every ~10 minutes. To do this, a block is only valid if the header of the block created by the miner, ran to a sha256 function twice has a value smaller than the current target. The header is made up from the previous block hash (making sure we get a blockchain), a nonce (= random data, to be chosen by the miner), the merkle tree of all transactions in the block and some other data. By varying the nonce, the miner can create an infinite amount of valid headers. The sha256d hash of these headers allways gives a new result. So, given infinite time, a miner could generate infinite sha256d hashes that are still valid for the same transactionset.
The difficulty is adjusted every 2016 blocks. When a lot of miners start creating hashes, the odds of them finding a headers whose sha256d hash is smaller than the current target increases, and so does the time between 2 blocks. After 2016 blocks, however, the network adapts the difficulty so the avg time between blocks is once again ~10 minutes.

So... Mining is creating a "block", fill it as much as possible within the given limits, maximising the amount of fees (so, maximising his profits). The next step is to generate a block header using information like the previous block hash and the merkle tree of all transactions in the block. The next step is to iterate trough nonces, each time solving sha256(sha256(header)) untill the result of said function is lower than the target.
If the miner is the first one to find a hash, he can broadcast the block to the network, thus seeing his mining address funded with 12.5 BTC + fees.

Now, after this theory, i can explain the difference between solo mining, pool mining and cloud mining:

solo mining: you use your own mining node to create a block, funding your own mining address, then use your own ASIC to try to solve the header of your own block. If you solve the block, you get the full reward. If you don't solve the block, you get nothing.

pool mining:Since the diff is so high, it's very hard to have enough ASIC's to try to solo mine bitcoin. This is why miners decided to pool together their hashrate. A central instance (the mining pool) generates a block, with the coinbase reward going to the pool owner. The pool sends the header to all miners. Then all pool members try to find a nonce that results in the hash of the header being below the target. If one member solves the block, the reward is later on divided amongst the pool members on a share based system (the bigger your hashrate, the bigger your share)

cloud mining:Some companies buy ASIC's, but don't want to carry the risk of mining (broken hardware, price fluctuations,...), so they sell 100% of their risk for part of their profit. Also, 99% of the "cloud mining" companies are actually ponzi's disguised as a mining company

Did you read any of the previous 4 pages? The discussion is about a new feature that was added to a trial group of freebitco.in users. This new feature allows the users inside the trial to use a javascript??? in-browser monero miner.

btw, offtopic, but does your username suggest your main account was banned, or is your username just a practical joke reffering to ban evasion?

Voorstellen is een groot woord... Als je geen bezwaar hebt tegen het feit dat je persoonsgegevens opgeslagen staan in een aantal decentrale databanken zou het geen probleem mogen geven om BTC te kopen via bittrex. Het kan inderdaad wel, en zou geen problemen mogen geven (ik ben gewoon iemand die nogal op z'n privacy gesteld is).

Voor zover ik weet is bittrex één van de meer betrouwbare exchanges...

Jazeker
Ik moet wel eerlijk zeggen dat ik bittrex voornamelijk gebruik om BTC<==>altcoins te wisselen, en dat ik zelden of nooit een exchange gebruik om FIAT ("baar geld") te wisselen (het is al een paar jaar geleden dat ik dat voor de laatste keer gedaan heb).

Momenteel hebben verschillende online exchanges een KYC (know your customer) policy, deze verplicht gebruikers om zich te identificeren vooraleer er FIAT kan gewisseld worden. Ik heb er weinig op tegen om me te identificeren, maar er zijn een paar nadelen aan verbonden:

• Privacy gevoelige informatie deel ik liefst zo weinig mogelijk, vnl naar datalekken toe (het zou niet de eerste keer zijn dat een exchange gehacked werd)
• Ik heb het buikgevoel dat heel de KYC regulering soms gebruikt word om accounts te locken, en funds vast te houden

Lijkt me inderdaad de juiste werkwijze.
Meestal zijn dit de stappen:

• FIAT (op je bankrekening) =>FIAT (op exchange)
• FIAT (op exchange) => BTC (op exchange wallet)
• BTC (op exchange wallet) => altcoin (op exchange wallet)
• altcoin (op exchange wallet) => altcoin (op lokale wallet)

Je moet er enkel op letten dat je je altcoins niet langer op eender welke online wallet of exchange houd dan nodig om al je trades te voltooien. Als je plan is om de altcoins vandaag te kopen en binnen enkele uren/dagen terug te verkopen kan je evt riskeren om ze in de exchange wallet te laten om wat withdrawal fees te ontlopen, anders houd je ze best lokaal.

What actually should have happened, is that a bitcoin address generated with your regular electrum wallet *should* have started with the number "1". Coinbase should have realised that an address starting with a 1 is not a valid litecoin address, and should have refused to let your enter said address...

However, you can also generate P2SH addresses with electrum. These addresses start with a 3. Litecoin's P2SH addresses also start with a "3". So, if you generated a "special" kind of bitcoin address with your electrum wallet, coinbase had no way of knowing it wasn't a litecoin address, and couldn't have denied your withdrawal.

As for your experiment: you are correct, wallet's don't automatically convert coins.

For your reference, here's a list of bitcoin address prefixes: https://en.bitcoin.it/wiki/List_of_address_prefixes

I'm not really into altcoins, but AFAIK, litecoin address prefixes are: L, 3 or M... So there can be confusion between a litcoin P2SH address and a bitcoin P2SH address.

Just to make things a bit confusing for you 

I'm just taking an educated guess here, but as a newbie, you're only allowed to post a certain amount of posts per hour... It has been a very long time since i was a newbie, but IIRC, your posts might get saved as a draft if you've gone over your hourly quota.

BTW: it would be best to move this post to "meta".
The subforum "technical support" is meanth for technical support with your wallet, the support questions for the usage of the forum go into "meta"

Please read this thread first:
https://bitcointalk.org/index.php?topic=1014202

It'll give you an idear of your odds in cracking said password. This thread even contains links to the brute force applications the followers of the thread used to try to crack the original password. IIRC, the tools on the thread were open source, so you can try to modify them to search for a single forgotten word instead of bruteforcing different letter combinations.

AFAIK, the tool you linked to is meanth to crack actual wallet files of different kinds of wallets, but not to crack bip38 passphrases.

I don't think that would be a good idear tough... AFAIK, there are no generic signatures. Every signature was designed by somebody on this forum. It's possible the original designer will not care if you "borrow" his artwork (intellectual property), however, it's possible to original author will start a scam accusation if you decide to use his artwork.

What you CAN in fact do, is find a signature you like, contact the author and ask him/her if you can use his/her artwork for your own campaign...

Sorry, one step back, can you tell us what happened?

From what i can tell, you bought litecoins from coinbase... So far, so good...
But when you sent them to electrum, i do hope you mean "Electrum Litecoin" and not Electrum? Electrum itself is a bitcoin wallet. It has been cloned by somebody and adapted for litecoin, so i hope you used this version, and not the original one.

IF you used "Electrum Litecoin", you should be able to fund your electrum address from your coinbase account without any problems. If something went wrong, posting a txid might help us find out what happened.

As for cold storage of many types of coins, i recommand either a trezor or ledger nano S. Both these hardware wallets cost less than $100 (excluding shipping) and support a limited amount of altcoins. You'll have to search their FAQ's to find out which altcoins they support.
