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!

The blockchain is particularly slow today. I sent bitcoin today and paid around $4 as the transaction fee, which normally means that the transaction is confirmed within half an hour. Today the confirmation took more than 2 hours. So I would suggest patience, and eventually your transaction will be confirmed.
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.

Well sir I checked that you are having 3USD fees, so it should get confirmed pretty soon. Last week I had a 0.3 USD fee transaction waiting for about 5 days, but eventually it got confirmed. But it was 10x smaller fee. So if you are not in a great hurry with your transaction, you can wait and it will get confirmed. There are webpages detailing the number of transactions with a given fee or above that are still waiting for confirmation, so you can use those webpages to estimate remaining wait time. Or use the webservices like confirmTX but there has been recently doubts on whether the page owners are honest, you can find the thread on it and make your own mind Hope this helps you! I have said this so many times before, but i'll say it again: the fee necessary for a reasonably fast confirmation has NOTHING to do with the value of the outputs of the transaction, not the value in BTC, nor the value in FIAT. There are 3 things influencing the fee: - the AMOUNT op inputs (NOT their value)
- the AMOUNT of outputs (NOT their value)
- wether or not the sender is using a segwit wallet or not
In the OP's case, he used a fee of 55 sat/byte, while https://bitcoinfees.earn.com/ teaches us that at the time of writing, you'd need a 200 sat/byte fee for a 95% chance of getting in the next 3 blocks. The good thing is that his fee is over 10 sat/byte, and his transaction size is under 400 bytes, so most free transaction accelerator services should allow him to accellerate his tx for free.

MY previous post on this thread...they won't take it if your transaction is TOO low....I did a couple (see my previous post) one went thru at 2c in an hour! Without an accelerator helping ...because original fee was too low....The other later...but is sucks to wonder you can try the acclerator..if the fee you originally did on the BTC transaction is too low the viabtc app will tell you i mean did he already try to use paid service from viabtc? I know if free service doesnt accept transaction if the fee isnt 10 sat/b or higher. But if you scroll down, they say if they offering paid service. ViaBTC’s Transaction Accelerator is a FREE service for the community. We also provide paid accelerator service for special cases such as urgency, extremely low transaction fee etc.Fee standard According to transaction size, a donation of 0.01 BTC or BCH per KB is required for each transaction. Please contact support@viabtc.com for details. I mean, he can try contact them first and ask for paid accelerator service if OP want to use paid service. If i'm not mistaking, the payed acceleration service will even work with a 0 fee transaction (as long as you get it broadcasted). BUT 0,01 BTC/Kb is huge... His transaction is 0,559 Kb, thus would need an "extra" fee/tip/... of 0,00559 BTC, bringing his total fee up to 0.00000336 + 0,00559 = 0,00559336 BTC, which is almost 1/3th of the value he's depositing...

Ik zie dat je bitcoin core aan't gebruiken bent... Deze blijft transacties rebroadcasten. Als er een probleem is met de transactie (bijvoorbeeld een véél te lage fee, of een dust output), blijft je wallet deze "slechte" transactie dus keer op keer rondsturen, waardoor hij keer op keer terug in de mempool van de nodes zal worden geduwd.
De "oplossing" is vrij simpel: ga naar het debug scherm, open de console, probeer het commando "abandontransaction " met hierna de transactieid die je in je historiek kan vinden door rechts te klikken op de transactie die 0/unconfirmed is. Als dit niet zou lukken, kan je altijd proberen om je wallet op te starten met de extra parameter -zapwallettxes . deze parameter zorgt ervoor dat er een volledige rescan gebeurd, en dat al jouw niet-geconfirmeerde transacties gewoon vergeten worden door je wallet.
Na één van bovenstaande methodes moet je een paar dagen wachten vooraleer de transactie uit de mempool van de meeste nodes verdwenen is, hierna kan je opnieuw proberen om de unspent output te gebruiken. Ik zou je aanraden om een recente versie van bitcoin core te installeren, je kan altijd (voor de zekerheid) een backup maken van je wallet.dat

Try some paid service from viabtc. Looks like they accept paid service if you in urgent or in very low fees. I hope this can help you. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FCms4Oww.png&t=665&c=atu06nwZjYfxYg) MY previous post on this thread...they won't take it if your transaction is TOO low....I did a couple (see my previous post) one went thru at 2c in an hour!

There are a couple services out there that do accept tx's with such low fees, but most of them are paying...

The transaction will go through. If you sent it with a very low it should still go through just takes way longer. Maybe 1 Month?
Not really... It *might* go trough. At the moment, the unconfirmed transaction is stored in the mempool of the nodes. The default setting of most nodes is to remove unconfirmed transactions from their mempool after 72 hours (IIRC). This setting can be modified by each node individually (for example, my node keeps an unconfirmed tx for 10 days, but other nodes might keep tx's only for a couple of hours). IF a transaction only has a fee of 0,6 sat/byte, there is a chance it will remain unconfirmed for such a long time that most (mining)nodes just dropped the tx from their mempool, either because it stayed there for to long, or they rebooted, or their allocated memory was full and they dropped the lowest fee tx'es

As long as it's an authorised reseller, i wouldn't worry to much... I bought a ledger HW.1 and a ledger nano S, and IIRC, the boxes were packaged in plastic, and if memory serves me right, at least one of them had a security seal (on the box). To be honest, i bought both devices when they first hit the market, so it has been a while since i did an official "unboxing". Anyways, if you use the official bootable usb image to initialise your ledger, and you make sure it has the latest firmware from ledger, and use the official ledger chrome plugin to open the wallet for the first time, i think you're very close to being 99,99% safe ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

What does the broke common man do with $200 to get started in the Crypto Market. Which exchange is best for the broke man? Can a broke man trade bitcoin/altcoin without an exchange? Coinbase vs BitConnect vs Bittrex vs Coinigy? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) What would my Crypto Guru's do?? Don't get me wrong, i love the bitcoin technology, and part of the bitcoin community... But crypto currency will remain a high risk high reward investment for now... If you are a broke man, i personally wouldn't invest my last $200 in BTC... But that's just my personal opinion. IF you really want to go trough, here's a partial list of possible BTC/FIAT exchanges: https://www.coingecko.com/en/coins/bitcoin/trading_exchanges#panelNext to this, you have localbitcoins, this forum and probably another 100 places where you can exchange. Do your homework and see which exchange gives the best rate compared to the fee compared to their trust rating...

Ledger Nano S have Anti-Tampering Seal but is highly recommended to buy from an authorised seller (eBay seller could open brand new Ledger and write down private keys then sell and take your funds in future)
This is not true. The wallet does not come with a tamper proof seal, as it is not required. The hardware checks itself every boot. See their support website here. An eBay seller could not write down your private key as long as you initialize your device before using it, generating a new set of keys. So when you get the nano ledger s... as long as you reset it, then your are fine 100 percent right? IF you got it from an authorised seller, and you receive a box that is still in it's original packaging, you're safe... IF you bought it from an unauthorised seller, there is alway the THEORETIC possibility he messed with the hardware and firmware, and when you initialise your hardware wallet without paying attention and testing if the firmware is original, you don't see a random seed, but rather a seed that was generated by the fake hardware from the fake seller (so the fake seller knows you will probably generate one of his 100? pre-programmed seeds). This option is for the truely paranoid tough ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

No worries man, i just accelerated it on my pool for you. Just wait for confirmation Which pool do you manage, cause if you pool finds less than 3 blocks/week on average, the odds of OP's transaction being dropped from the mempool of most nodes is bigger than the odds of his transaction ending up in a block from your pool... OP: i once wrote a tool to help people fix these problems: https://www.mocacinno.com/feecheck.php?txid=bb473c1155c018c16dd0216587ff4aa183f421d26cf3f38d67cb73af67efbfc4Since you say RBF and CPFP are out of the question, you can still try to double spend one of the unspent outputs you used as an input for your transaction, and try to broadcast it... If a couple days have passed, your original transaction might already be dropped from the mempool of some miner's nodes, so it might actually work (altough it's still a longshot) EDIT: please, people, stop talking about FIAT (USD) in relation to transaction fees... It does not matter how much USD you sent to somebody when you're talking about fees. A $30 transaction might need a $100 fee for a fast confirmation, a different $30 transaction might be OK with a $1 fee. It's all about the number of inputs, outputs and wether or not you're using a segwit wallet.

Wat een gedoe haha ik dacht leuk een nieuwe hobby..
Maar goed. Ik heb het programma bitcoin knocks gedownload en die is in tegenstelling tot Armory super snel met het downloaden van de history. Maarrrrrr Ik heb dus aangeschaft met de code welke armory had gegenereerd. Ik heb de code en gegevens die daarbij horen. kan ik deze dan zo in bitcoin knocks zetten? Of moet ik (inmiddels al meer dan 36 uur) wachten tot Armory klaar is?
En wat vul ik waar in?? Armory had een Ontvangstadres gegenereerd en die heb ik. ik zie ook dat de bitcoins daar aan zijn gekoppeld in de omgeving van litebite. Daarnaast heb ik een Netwerk ID (txid) erbij gekregen. Is er nergens een stappenplan waarbij deze gegevens staan omschreven en wat je waar invult? Ik kan me namelijk voorstellen dat de wachtwoord die ik heb gemaakt ergens in deze zit versleuteld.
Is Knocks niet van de Gulden wallet i.p.v Bitcoin? Als je namelijk je Bitcoin(s) verstuurd naar een wallet van een andere cryptocurrency zal je je Bitcoin(s) verliezen, Let daar dus goed op! Geen idee, ik vermoed (hoop) dat het gewoon een typo is van de OP en dat het over bitcoin knots gaat ( https://bitcoinknots.org/). Deze is op zich veilig (AFAIK). Toch blijf ik bij m'n eerdere posts: als de synchronisatiesnelheid een probleem is zou de OP moeten overwegen om een spv wallet zoals electrum te gebruiken. OP: als je echt wilt overschakelen van armory naar knots (of electrum), exporteer je de private key van het adres dat je als depositaddres opgegeven hebt by litebit, en daarna importeer je deze private key in je andere (nieuwe) wallet. Voor het exporteren: http://docs.bitshares.org/muse/migration/howto-exporting-wallet-clients.htmlVoor het importeren in knots (dewelke een fork van core is, dus de core how-to zou in principe moeten werken): https://en.bitcoin.it/wiki/How_to_import_private_keys

i need someone who very reputable here fix my website. its a small job and i dont have big budget. pls leave me your contact in pm so i can contact you
It might be a good idear to tell us what needs to be fixed... Your design, a standard script installation, backend scripting in python, a ruby on rails script, your database schema,... As long as your question is so vague, i don't think you'll get a lot of offers, since nobody knows if your job falls within their skill set.

I am only using $mysqli->real_escape_string(var) to clean user's input and cookie, is it enough ?
Well, the consensus is to treat any data that is modifiable by the user as unsafe... That's why i would suggest to 1) check the data type... If you expect an email, use FILTER_VALIDATE_EMAIL, if you expect a number use is_numeric, ... 2) clean all the input, unless it's a variable you got from a trusted source that was previously cleaned (for example, data you fetch from your database, and that was verified and clean when it was entered) 3) start using prepared statements 4) lock down your database privileges. Make sure the mysql user entered in your config file only has the privileges he really needs to perform his tasks... If the user doesn't need "insert" privileges on a certain table, make sure he doesn't have this privilege... And i only store faucet balance in a file for displaying purpose only, they began attack before i use it.
I'd personally suggest you just fetch this data from your database... Opening local filehandles and using system calls are always more risky (in my opinion). An attacker can use these filehandles to write code to a file, then execute it. System calls are also a common attack vector (who wouldn't want to touch files, change their permissions, cat files,...) You could also doublecheck the owners of these php files and the folders, and the file/folder permissions... Can you share the url where you installed this vulnerable script? I can do a quick vulnerability scan when i get home... It's usually easyer to work this way than to browse trough your sourcecode ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Also, the accesslog from around the time where you were breached might be interesting information. Once again: i didn't really dig into your sourcecode... The things i said in this post are merely good housekeeping rules i use myself when writing scripts... It's possible the attacker used a completely different attack vector

I didn't have time to look trough your script (i just had a quick look at your index.php, without really digging into it), but the first remarks: - you don't use prepared statements - it doesn't look like you always clean up any user input - it looks like you store data in local files: for example: $fp = @fopen('balance', "r");
I'd suggest by verifying ANY input you get from your user, including cookie data. I'd also suggest to stop writing to local filehandles and to start using prepared statements.
this might have nothing to do with why your script is vulnerable, it's just some general housekeeping rules: never trust any user input, use prepared statements, don't read or write to local files...

Ik heb bitcoins gekocht en laten sturen naar een adres wat het programma armory (gedownload) opgaf. Nu zie ik dat ik ze gekocht heb, maar zie ze niet in armory staan. Armory is druk aan het scannen. Ik heb het net geïnstalleerd. Duurt dat scannen dan lang? Of ben ik het kwijt? wie weet het?
Het is momenteel redelijk druk op het bitcoin netwerk. Elke overboeking (transactie) met bitcoins kost geld (transferfee). Al die transacties moeten in een blok worden verwerkt. Zo'n blok wordt gemiddeld elke 10 minuten "gevonden" en dan gevuld met transacties - waarbij de miners (dat zijn degene die de blokken "vinden") natuurlijk eerst de transactie pakken waar ze het meest aan kunnen verdienen. Is er dus weinig betaald kan het langer duren voordat je de transactie kunt zien in jouw wallet (=armory). Je kunt op (bijvoorbeeld) blockchain.info jouw bitcoinadres invullen; hier kun je zien of er een transactie onderweg is, of zelfs al binnen is. Dus als ik het goed begrijp moet eerst 3 jaar aan transacties worden geladen voordat de wallet op de pc functioneert. Euhm, de eerste transacties waren in 2009. 2017-2009 = 8 jaar aan transactiedata ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Maar je idee was wel correct, je moet alle historische blokken downloaden en scannen (tenminste tot de blokhoogte van de block waarin jou transactie gestopt werd) vooraleer je balance aangepast zal worden. Als je dit in de toekomst zou willen vermeiden had je eigenlijk een SPV wallet zoals electrum kunnen gebruiken... Maar omdat het importeren/exporteren van private keys nogal moeilijk is voor een beginnende user, zou ik je aanraden om gewoon af te wachten. Als dit écht te lang zou duren moet je het maar weten te zeggen, dan proberen we je te helpen met importeren/exporteren van private keys

For the way i currently use a mixer, i would personally vote against smaller chips... If i want to mix btc, it's usually at least 0,1 BTC... I'd never mix smaller chunks, so i dont' need smaller chips. but that's just my personal use case.

Does that even make sense with the current transaction times and fees? You are going to pay more for the fees than for your meal. Unless the fees go down drastically, it makes no sense to use bitcoin as a daily payment method.
True, the average fee for an average non-segwit transaction at this moment is 38,420 satoshi's (0.0003842 BTC), in fiat that's about $4. However, there are ways to avoid these fees: - use the lightning network (in the future): no need to wait for confirmations, very low fees - use a segwit wallet: lower fees - use a prepaid card: fund your card using $100 or more in BTC, the funds only become available once the transaction is confirmed, the card doesn't expire, so the user can just fund it once and use if for loads of meals... This would allow users to cheap out on the fees, as long as they funded their prepaid card a couple of days in advance. I'm not saying that this is what mc donalds will be doing.. I'm just saying there are ways to lower the impact of the high transaction fees.
