Better to Mining (Altcoins) since GPU rigs can't mine Bitcoins.

---

@DRAHdk Both GPU were outdated for mining Ethash (for Ethereum and forks) nor "mainstream" Altcoins, though 1050Ti can mine a lot of "Shitcoins".
I suggest you to go to whattomine.com to find the most profitable (or rather: less wasteful  ) coin to mine using those GPUs.
Then go to the Mining (Altcoins) board and find the suitable miner for your OS and selected coin to mine.

Are you for real? The average mempool size has been low to normal since Friday.
And OP said that the transaction was "a few weeks ago", the chance that it's confirmed by now is 99% even if it a 1sat/byte transaction.

He haven't heard from him since then so this case might be solved already.

The "Gears" icon, it's an unconfirmed transaction which might occur even if the tx was already confirmed if the wallet wasn't synced or offline.
Like this:


I suggest to follow the posting instructions listed on this sticky thread: [READ BEFORE POSTING] Tech Support Help Request Format

If you're looking for a legitmate pool, go to Mining (Altcoins) > Pools.
This thread was posted in the wrong board and there's no info in the OP.
More or less, it's not any better than the others.

You can try on Services > Currency Exchange and wait of a Green Trust members (Users with Green +1~ below their names) to reply an offer.
The rates are quite good, mostly depending on the current price, they accept Paypay too.

As long as it's not another long discussion, I think it's fine;
You must lock this topic if you want to create a new thread though, click the blue "lock topic" button just below the page (bottom-left).

If it's new, there should be "1+ confirmations" displayed below the tx, are you sure that it's a legitimate blockexplorer?

If it's unconfirmed, that guy must have used the same input to a new transaction, it's called "Double-spending", it's possible if the transaction doesn't have a confirmation yet.
Usually, scammers time this during "heavy mempool times" when transactions are taking a lot of time to get a confirmation (like last week till yesterday).

Do you know the address that was used by this "one guy"?
If you do, type it to live.blockcypher.com and it will show you the latest transactions, what differs it from other explorers is: double-spend attempts will be displayed (in red as: Double-spend attempt!) as long as the other invalid-unconfirmed transaction is still in their mempool.

Just copy and paste the wallet.dat backup file to the default %appdata% storage of roi-coin wallet.

I only know the location for the Windows version which is:  C:\Users\*ComputerName*\AppData\Roaming\roicoin\
or open "RUN" Windows+R, then type: %appdata% and press Enter, open roincoin folder.

He just got lucky, the average mempool size suddenly dropped to 10+mb that made his 1sat/byte tx possible for a 12-24hours-confirmation just as I mentioned earlier.

@maxttilt You can now lock the topic (lower-left button) after editing the title like "[SOLVED] Title".

Yes based from that, it wasn't sent yet and it isn't "pending", it's just your wallet that knows that particular Tx, not the whole Bitcoin network.

The right way to send a transaction is: Click "Sign", type your passphrase then click "Broadcast".
After that, it will be added to the history as "Unconfirmed" and that will be successfully sent after receiving 1 confirmation (though the vendor might accept it after 4-6 confirmations).
You can safely remove the local Tx and your balance will return to normal.

Also, read the warnings and instruction in the above replies.

If it was being displayed as "Local [rbf, 56. sat/b]", the transaction wasn't sent yet.
To confirm it, copy the transaction ID from the details and paste it on an online Bitcoin blockexplorer: https://www.blockchain.com/explorer. If there is no result, it's not yet broadcasted.

Warning: do not broadcast the local Tx since the vendor might have set an expiration to the payment invoice.
Simply delete it and your balance should return (it wasn't actually deducted) and try to contact the seller for a new invoice or not if there's no expiration and try again.
Also, take note that the current average fee is a bit higher than normal.

Your Chrome was updated so it shouldn't be the vulnerability.
There's are various Malwares/Viruses that can do the exact thing even after being detected by an antivirus, those can do their job before the detection.

Happened to me once (long time ago): my AV detected and successfully quarantined it but after that, in every page I visit, there's a chance that it will redirect to an advertisement.
I suspected that I got it from an online Ad page.
What it did was simply changed the proxy settings to its "home page/IP" which causes the redirection.

Scanning the PC wont help since the virus/malware was already quarantined, disabling or changing the proxy settings (from internet settings or/and Chrome's proxy settings) to default fixed the issue.

My BIP39 SEED was also created from iancoleman (offline- downloaded the code form GitHub) and so far, it's still not hacked.

The risks with the online site isn't the legitimacy of it, it's mostly the browser and malwares.
Next time, you might wanna tell the OP about the steps on how to use the offline version than using the online "risky" method.

Something like this:

• Download from github.
  
• Turn off the internet connection or transfer to an always-offline computer.
• Extract it.
• Drag and drop to the browser.

Do this ^.

@sumguy2017 To answer your question, that "Local" transaction was saved because you've clicked "save" after signing the transaction and forgot to click "broadcast".
The transaction was just saved in your Electrum wallet, not sent to the network and the total amount was locally deducted from the the total balance, it will return to normal if you delete it.

Next time, just sign the transaction and click "broadcast", it will automatically be included in the history tab without clicking "save".

If the average mempool doesn't return to a low value of 10mb, transactions like yours will likely never get confirmed based on 2017's same scenario.
If it miraculously gone down to average of 10mb, you will only have to wait for about 12-24hours for it to get confirmed.

By saying "return to your wallet", you must be talking about how long will the nodes keep that tx in their mempool, answer: most nodes will drop it after 14days, but some may not.
If you haven't changed the -mempoolexpiry setting, it will "return" after 14 days after your last re-broadcast.

Looks like they opt you in to their "Enhanced Verification" for some reasons and Driver's licence can be used for that, though it has the same risks.

Anyways, where did you get the message? Through Email?
Bittrex really does request for passports but make sure that it's them.

The main problem isn't the fee, it's the unconfirmed inputs (thought the 14sat/b fee will be a problem too).
Look at your link, it has the (U) icon after the input. Means that it's still unconfirmed and your transaction can't be confirmed before the parent transaction.
Confirmation time will still depend on your fee which will surely take time (it's eligible for viabtc though after the parent tx got confirmed)

The used input from the address: 3KGSTor1SZ3qsnyPGhjBCRtkpmTZWTJXKW from this transaction: 345e84b50780fcc0adc126ba49d2a246dd7a0a24886a4457a81dd2c3a1b127d9 is still unconfirmed (with 19sat/b fee).

If you're trying to use viabtc's accelerator, make sure to add the parent transaction since yours won't be eligible (not because of the fee).
I'll add it for you if the pool isn't crowded yet.

Really? It's all over the news, Development & Technical Discussion Board last April 1 and later on Bitcoin Discussion.
Here's one: Softfork proposal for minimum price of $50k USD/BTC

And there I was expecting for a correction then suddenly people got fooled by an April Fools joke! Boom $5k.
I'm pretty sure it's because of that joke, otherwise, it's a well-timed Pump.

What I mean is the "additional fee" that he can use based from the available change.
But I think that it's not possible since the minimum sending amount is 546 Satoshis which also applies for the change... so the maximum fee that he can add is +3sat/b not 4 in my previous reply.

Still not worth the effort.

The highest increment you can make using RBF is +4sat/byte and still not enough for a "regular speed" transaction at the moment.
It's based from the size of the transaction: 589 bytes (x4=2356) and the change amount: 2376 satoshi (I don't know if the network will allow a <10 satoshi change Haven't tried it, maybe not).
But were talking about a SegWit transaction and blockchain.com often fails to display the accurate data of a SegWit Tx, could be lower or higher.

Or if the sending amount isn't an issue, do a double spend attempt by enabling coin control and by deleting your mempool (warning: not beginner-friendly).
This way, you can re-spend the same inputs to make another transaction (with lower sending amount and higher fees)

OTC (Over The Counter) trades are handled by brokers who are mostly from famous Exchanges, and thus everything is traceable including the fiat money used.
What aren't traceable are the Peer-to-Peer trades that didn't took place in any Exchange, example: our Marketplace board (which isn't considered as OTC, there's no "counter").

Yep, it's meant for really huge volumes (about more or less $200k-$1m+) and the trades were excluded in the exchange's volumes even though OTC trades are often offered by the Exchanges themselves.
It's basically, them Whales trading with each other with the help of the broker(s), their trading volume is isolated from the Exchange's volumes.
