Hello it happened me that a transaction was unconfirmed and I posted here and another user kindly submitted my transaction for acceleration. If i give you the transaction id could you help me with an unconfirmed transaction for some hours now? The fee is about 25 satoshi/byte I think. Thanks in advance.

Bad TX fee, stuck TX.....love it. Welcome to your first failure, one of many. The TX will eventually go throught, you can mine it yourself if you want.
Remember to pay higher TX fee.

It's already confirmed. Onnz423 submitted it to the ViaBTC accelerator and the ViaBTC pool confirmed it for the OP 12 blocks ago.

This is the link to the accelerator if the OP ever needs it again.

Thanks for your reply. I did it yesterday and i dont know where the money went i have not to put any bitcoin adress... i thought that it will be exchange directly to my jaax wallet, what i could do now?

Try using the procedure in the quote if you mean shapeshift sent Bitcoin to your Jaxx wallet, but they aren't showing in it.

I haven't used Jaxx myself but apparently it often has problems syncing. Try installing the mycelium wallet on your phone and importing your jaxx wallet's seed words into it. Another user tried it and found the mycelium wallet recovered his Bitcoins.

There are similar complaints in this thread. This one reply says jaxx switches address automatically at certain time intervals, and often has problems syncing, so balances don't get displayed correctly. If that's true there's a chance your coins might still be accessible.

Donīt worry about the changed address. The address changes automatically at certain time intervals. Nevertheless, any previous address is still valid and can still be used.
I have just looked in my wallet: I am also missing some coins. But thatīs not because the change of your adress. Jaxx currently must have a problem when retrieving the blockchain, so not all coins will be displayed. You can simply enter your t-address at Zchain11 and then you can see that all your coins are still there. Hopefully, Jaxx fixes the problem quickly!

Try importing your jaxx wallet's seed into mycelium's android wallet and see if your coins show up in it. According to this post the two wallets can use each others seed.

Don't ever use that private key you posted again. It's related address has received 0.25393524 BTC. The last withdrawal from it was on 2017-05-20.

That private key is not his. It is the one from the wiki article I've linked above. He posted it here to tell me that his key was in that format (WIF).

I thought it was his, I was using it to check importing compressed and uncompressed private keys into Electrum. You're right electrum supports both (and mini private keys in 30-character format). I should have tested it before posting.

The reason I thought otherwise was I remembered one of your posts advising someone that a private key needs to be in WIF to import into electrum.

The private key needs to be in wallet import format:

https://en.bitcoin.it/wiki/Private_key#Base58_Wallet_Import_format


That answer appeared to allow the user to import his key into electrum, although his reply was vague. He said it was because the key needed to be uncompressed, but he must have been mistaken.

You are so right, thank you for the link. The Private Key needed to be uncompressed, and in fact Electrum recognized it; however the problem is the HD wallet does not support Sweeping so I'll have to create a non-HD Standard wallet to complete the procedure.

Thanks for the tip! Keep up the good path!

I'm not mistyping the public address, which I can check on blockchain

If it works on blockchain it should work on the wallet.

About as sure as one can be I'm not mistyping the private addy either

I can try either, it never even lets me move forward*. Next is just greyed out.

edit -

This is the format my private addy is in (5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF) and I just type it in that format into the box

The public one is like that but slightly shorter. And again works fine with blockchain info



Don't ever use that private key you posted again. It's related address has received 0.25393524 BTC. The last withdrawal from it was on 2017-05-20.

I just converted the private key to an address and checked it on a block explorer.

1905  Other / MultiBit / Re: MultiBit on: July 15, 2017, 02:23:51 PM
The reason I export my keys is because of this August 1st thing.
What will happen to multibit classic if bitcoin hard forks? My understanding is that (because multibit does not get updated) only one of the 2 chains will show on multibit.
So I need the private keys to be readable from another wallet in case a hard fork occurs.
Yes I know having plain text private keys is risky, but are the multibit-encrypted private keys importable to another wallet? Or should I decrypt them first according to the above instructions posted?

I don't think there will be a fork, but if there is one wait until after it, then decrypt your private keys and import them into another wallet.

However, multibit classic isn't being developed anymore, so it's advisable to switch to a different wallet even if there isn't a fork.
1906  Bitcoin / Bitcoin Technical Support / Re: lock time?? on: July 15, 2017, 02:13:46 PM
Your transaction is confirmed now. Its lock time was block 475903 and it was included in block 475912 (nine blocks after its lock time).

You presently need to pay 270 satoshis/byte to get fast confirmations, and your transaction pays 150.29 satoshis/byte, which is about half that fee.

You can find the best fee to pay for your requirements at this site.

1907  Bitcoin / Bitcoin Technical Support / Re: Need help to identify these 2 addresses on: July 15, 2017, 09:35:37 AM
I have been scammed by these 2 addresses.

Is it possible to tell which exchange these addresses belong to? I might contact the exchange to know the user then.
Its near impossible to track those addresses specially they are belong on an exchange wallet and I don't think that those exchanges would bother to search up those things for you. Knowing that they are busy on doing things and they will unlikely to get serious on this kind of cases. Would like to know how much did you lost? This is really a hard situation when someone scams you through btc transfers its nearly considered as lost forever and don't bother to look up.
I have been scam victim of almost $3.5K in Indian rupees.

There is a free service that can sometimes detect if an address belongs to a particular exchange or service. Sadly it doesn't identify your two addresses. This is the free service's website.

https://www.walletexplorer.com/

The people who run the free service also operate a better service that you have to pay to use. Maybe that could identify your two addresses. This the paid service's website.

A user with a similar problem found that his paper wallet's private key was in compressed format, and needed to be in uncompressed format before electrum would accept it.

An offline copy of this website can convert a private key to uncompressed format.

https://www.bitaddress.org/

These quotes show the user's problem, and the solution.


When I select

wallet>private keys>sweep

Window opens & I paste private key from paper wallet - but the "sweep" button does not highlight, stays inactive. Assumed private key was incorrect, but I tried four different ones, several times, and still nothing. Has this function been removed from this version?

If so, how to?

1909  Bitcoin / Bitcoin Technical Support / Re: Lost bitcoin? on: July 14, 2017, 06:20:27 AM
Do you know which address you sent the coins to? If you know which address you used then try the instructions below starting from the point where "extracting the private keys" is explained.

If you don't know which address you used then try the instructions below, but starting from the beginning of them.





Search for all the Bitcoin addresses that Bitcoin-QT shows on this website. That site will tell you if an address contains Bitcoins.

http://blockchain.info/

To view the addresses in Bitcoin-QT click "file" in the menu, then click "receiving addresses" in the drop down list that appears.



If blockchain.info shows an address contains coins you can either wait for up to a week for Bitcoin-QT to sync, or use a different wallet to spend them immediately.

If you want fast access to your Bitcoins you need to extract their private keys from Bitcoin-QT, then import those private keys into alternative wallet software like electrum.

To extract the private keys click "help" in the Bitcoin-QT menu, then click "debug window" in the drop down list that appears.



Click the tab labelled "console" in the debug window that appears.



Type dumpprivkey, then a space, then your Bitcoin address in the text box at the bottom of the console window. This is an example.

dumpprivkey 1Cgu5PQyTYrZn4VtAs2T1FHf1ayXVYHNDt



Afterwards press your enter key to view the private key for your Bitcoin address. There's an example private key (L4RY4tv1Qpr4FVxtSLnr7vJiUCvk7A7C2Cd6M7QSU2BkRtj9vhnd) shown in the screenshot.



Copy the private key, then download and install the electrum wallet from here.

https://electrum.org/#download

Use your private key(s) in electrum using these instructions.

http://docs.electrum.org/en/latest/faq.html#can-i-sweep-private-keys-from-other-bitcoin-clients

Those instructions send your Bitcoins to your new electrum wallet. After the transaction has six confirmations you can send your Bitcoins from electrum to wherever you like.



1910  Economy / Speculation / Re: HODL on: July 14, 2017, 01:45:53 AM
The price keeps getting yanked up and down so unpredictably that it's safest to HODL, and that's what I'm doing. I though it would crash at $2000, but it defied my expectations and continued climbing to $3000. After reading about people selling at $1800 in the hope of buying back in at $1000 I abandoned any thoughts of trading and decided to stick with HODLing. The market's just too unpredictable for me to risk trading.
1911  Economy / Speculation / Re: 1st Aug event: Possible Bitcoin pump? on: July 14, 2017, 01:14:20 AM
IMO there won't be a fork, Bitcoin will continue as it is. The biggest thing holding the price back today is fork fear, and after that's gone the price will continue upwards. There will probably be a stampede of people buying back in after the fork fear's gone.
1912  Bitcoin / Wallet software / Re: As long as I have my private keys...? on: July 13, 2017, 07:54:25 PM
The best thing you can do is backup your Jaxx wallet's seed words. Jaxx uses a system where it can generate an almost limitless number of addresses (and private keys) from its seed words. If you only back up the private keys your wallet currently contains it may generate more, then crash. You risk losing coins in that situation if you didn't back up the seed words.

If you have the seed words for Bitcoin addresses you can import them into an alternative wallet like mycelium which will restore access to your coins. I advised someone who had a malfunctioning Jaxx wallet to try importing into mycelium some time ago and it worked. You can read about it here.

^^ This worked! Thank you so much!

 And the Seed phrase is that random string of words that it tells you you must remember and don't give to anyone? If I have that, then I can use any wallet?

 Also that seed word phrase would also work for altcoins not just Bitcoin's right ?

It will work for altcoins if you can find a wallet for every supported altcoin that can import Jaxx seed words. I haven't used Jaxx and don't know all the altcoins it supports. There could well be some altcoins that can't import Jaxx seed words, in which case you are best backing up the private keys too.

This quote says jaxx automatically switches address every so often. If that's true, and it switches to newly generated addresses, you might be continually backing up new private keys.

You could contact either quickseller or macbook-air and offer to pay a small fee to get it confirmed. Macbook-air is in charge of a mining pool that could confirm it, and quickseller has access to the pool's transaction accelerator. They don't charge very much to get transactions confirmed.
1916  Bitcoin / Bitcoin Technical Support / Re: How to store wallet on USB and load it with the Bitcoin Core? on: July 13, 2017, 09:26:36 AM
This is a very bad solution, to move it all the time.
I thought there is a more professional way of doing it.



If you want to store your "Encrypted Wallet" permanently on a USB you can install the whole of Bitcoin core to the USB, then follow the instructions in the quote to make it use the wallet.dat on your USB.



... Right click the shortcut and select "properties" from the list that appears.

Click the "shortcut" tab in the properties window, then look for the first text box in it labelled "target". Copy the line of text below and paste it to the end of whatever is in the "target" text box.

-datadir=.

Make sure you copy the leading space and trailing . from the line of text above.

The text box should look something like this.



Afterwards click the "apply" button, then the "OK" button to close the shortcut properties window.


Copy your encrypted wallet.dat file to the same folder on the USB that contains bitcoin-qt.exe.

Double click the new shortcut to run Bitcoin core. Don't double click bitcoin-qt.exe because that will make Bitcoin core look for a wallet.dat file on your computer rather than on the USB.

As achow101 says your USB wll need to be over 120 GB to run Bitcoin core from it.
1917  Bitcoin / Bitcoin Technical Support / Re: Transaction does not exist on: July 13, 2017, 12:44:20 AM
Seems they are slowly filtering through... I also noticed that it seems to be a big "web" rather than a tree...

A lot of the outputs from the earlier unconfirmed transactions, are actually inputs into that "giant" transaction: https://blockchain.info/tx/449083b66531b4a38188b255ee19c224264ead728467d2da254b8f0ebf453ce8

Quite a mess indeed... but they ARE slowly confirming... I've been rebroadcasting the "first" transaction after a group of unconfirmed transactions get mined... and it seems to rebroadcast the chain up to the max "mempool chain"... and that giant transaction now only has 15 unconfirmed inputs. Smiley

You are right, it's all due to you rebroadcasting through your node. I just tried broadcasting the giant transaction through coinb.in again and it gave the same "missing inputs" error as before. I doubt that transaction would stand a chance of confirming without your help.
1918  Economy / Exchanges / Re: Something bad is happening at Poloniex on: July 13, 2017, 12:24:15 AM
I've never seen a leading exchange get so much negative reviews. If for example EUREX or NASDAQ received so many complaints all over the web from unhappy customers, they would work extremely hard to improve their PR day and night.

Just the fact that Poloniex is completely silent about this astronomically high number of complaints and bad reviews is a huge red flag, this site might be having liquidity issues, or may be malevolent in intent and might try to outright steal customer funds benefiting from a lack of regulation in the crypto space. I would hope very much to be wrong, and for someone to step forward from their company to fix this huge reputational hit they've been getting over the last couple of months...

Simple. They know they can get away with it because they have the volume. That dwarfs any need to please customers. It's always been this way and it'll continue to be so until more discerning and demanding people get involved. However greed will always beat anything else.

It won't continue in US exchanges if the Uniform Law Commission draft uniform virtual currency act gets approved. Coinbase is strongly objecting to it. All exchanges regulated by it would have to give a bond to the department administering the act, and the department gets to specify the amount. There's a possibility of heavy regulation coming soon to all big US exchanges.

http://www.coindesk.com/uniform-regulation-virtual-currency-businesses-coming-state-near/

Quote
The Uniform Law Commission will vote on its draft uniform virtual currency act at its annual meeting in San Diego on 14th July.

Quote
If you are subject to regulation, the act requires you to be licensed with the state whose residents you conduct virtual currency business activity with. To get a license, you need to submit an application in which you must disclose extensive details about the background of the principals of your business, including fingerprints, criminal history, past bankruptcies, current or past lawsuits, enforcement actions or arbitrations.

Prior to being licensed, an applicant is required to post funds, a letter of credit or surety bond with the department administering the act in the amount that the department specifies based on the nature and risks in the applicant’s virtual currency business model.


Quote
Once licensed, you must comply with various requirements such as having a minimum net worth or reserves, creating and maintaining required records, making certain disclosures and implementing compliance policies including cybersecurity, business continuity, disaster recovery, anti-fraud, anti-money laundering, and anti-terrorist financing programs. You are subject to be examined by the department for your compliance with these requirements.

Non-compliance with these requirements or engaging in unsafe, deceptive, fraudulent acts or misappropriation of customer property, subjects you to enforcement actions which can result in fines, a revocation or suspension of your license or the issuance of a cease and desist order as well as, where appropriate, the referral of the matter for criminal prosecution.
1919  Alternate cryptocurrencies / Service Discussion (Altcoins) / Re: Moolah Scam on Mintpal - Reporting Missing Coins on: July 13, 2017, 12:10:27 AM
This guy only got 6 months in jail and victims didn't recover anything?? If that's true WTF  Huh

He's currently being tried in court for fraud and money laundering. He's accused of stealing one million pounds worth of Bitcoins and spending the money on a luxury lifestyle. The police have been investigating the case for the last three years.

http://www.coindesk.com/former-dogecoin-exchange-ceo-faces-fraud-charges-uk/


Quote
UK police have brought fraud and money laundering charges against Ryan Kennedy, the founder the now-defunct dogecoin exchange service Moolah.

Kennedy, who created Moolah under the name Alex Green, appeared in court today, according to a statement from the Avon and Somerset Constabulary. Though the exact charges weren't identified, police said the associated crimes took place during 2014.

The new charges, quietly announced on 29th June, follow a three-year investigation investigation by authorities in the UK, coming more than two years after he was initially arrested (and later released) by police.

Local authorities said in a statement:

"[Kennedy] has been charged with a number of offences under the Fraud Act 2006 and Proceeds of Crime Act 2002. It is alleged the offences were committed between January – December in 2014. This included the theft of bitcoins to a value in excess of Ģ1 million, that were then spent on a luxury lifestyle."

It was through Moolah, an early platform for buying and selling the meme-themed cryptocurrency, that Kennedy gained notoriety by sponsoring a NASCAR driver and later soliciting investments from community members through the distribution of a token.

Kennedy later purchased the digital currency exchange MintPal, which collapsed in late 2014 following a site relaunch and growing allegations of fraud that were levied against Kennedy. It was at that time that he first acknowledged that Alex Green wasn’t his real name.

He was ultimately taken to court by a group of developers who had launched their cryptocurrency through MintPal and accused him of stealing thousands of dollars in committed funds.

Kennedy is currently serving an 11-year prison sentence after being convicted last year on rape charges in the UK. He was arrested in relation to those crimes in early 2016, according to reports at the time.

...If I'm honest, it looks like this is being used to obfuscate funds so they may be likely to scam or be doing something else illegal.

Either that, or they created a tree of too many unconfirmed transactions for a miner to accept.

The chain of unconfirmed transactions leads back to one with fifty unconfirmed inputs. The first input alone is part of a chain of over 47 unconfirmed transactions. If all fifty of those unconfirmed inputs are also parts of chains of over 47 unconfirmed transactions then the OPs transaction has a tree of 2350 unconfirmed transactions leading up to it.

A recent typical block contained 1867 transactions with total fees of 1.77800286 BTC. The OPs transaction tree might have too many unconfirmed transactions in it to fit into a block..
