To make your post of better quality, why not include the link of where you found this out? Or if you saw the fake app on App Store, you can also screenshot it and include the link. But it is tue to always download Electrum from the official site and also to verify its PGP signature to make sure that the sjtebhas not been compromised. Electrum official website: https://electrum.org/[GUIDE] How to Safely Download and Verify Electrum [Guide] |

It would have been easier if Electrum can get its own coinjoin which would have made this easier. But you can still make use of a mixer to mix the coin. Send some of the coins to a mixer and let the mixer send you mixed coin which you can use to spend in the restaurant. Or make use of exchange like https://exch.cx/ to convert the bitcoin (that you want to use in the restaurant) to monero and back to bitcoin and use it for the spending. You can also convert to monero and back to bitcoin on https://bisq.network/ |

I am using Android and am on version 4.4.6
I have tried transferring the entire amount in my wallet and have tried transferring much less than the total amount in the wallet. Every time I get the same error. One thing I noticed is that the wallet details say it is "watch only." I created a new wallet and the wallet details info is much newer. Might be because I've had the original wallet for a long time?
I have screenshots but, don't have the time to upload them to a hosting site and attach here. The error code reads: Transaction created. Present this QR code to the signing device." Below that it says, "Warning: some data (prev txs / "full utxos") was left out of the QR cod as it would not fit. This might cause issues if signing offline. As a workaround, try exporting the tx as a file or text instead."
It seems that might be my issue is that somehow the wallet became watch only. Or, am I wrong? Quick search pulled up some complicated directions for sweeping the key??? Crunched for time or I would have done more digging.
Just like this error: https://bitcointalk.org/index.php?topic=5460116.0https://github.com/spesmilo/electrum/issues/8538You can see the answer here with this complaint: https://github.com/spesmilo/electrum/issues/8535Due to limited capacity of qr codes, we don't put full input utxos in qr codes, only witness utxos. For consistency, we do this for each input and always, not just when space would actually run out. Note that it is difficult to scan large qr codes close to the max capacity, so it is not desirable to always try to create qr codes near max capacity.
Hence it is normal that there is space left in the qr code you saw. This might be helpful as a solution: You can save the copied text onto a txt file or none, the important thing is the contents.
And send it to your offline Electrum, open the file "as text" or open using a text editor app and then copy its contents.
Is the offline Electrum also Android?
If so, you can import it via "Send->Paste", then you can proceed to sign and broadcast the transaction.
If Desktop, use "Tools->Load transaction->from text".
Or just like I have said before which I think would work, try and use Sparrow for the cold wallet and see if it will work. Sparrow is only available on desktop. |

You can use a cold wallet, or get yourself hardware wallet like Passport. You can setup a multisig wallet with hardware wallet and wallet like Sparrow or Electrum. Do not use online wallet if you can not afford to lose the coins. Use cold wallet. Please write to my telegram @leaneek
You are easily drawing scammers to yourself. You’re right, centralized exchanges are not supposed to be used for storing bitcoins. Move your bitcoins from Binance to Electrum or Blue wallet. I don’t understand why you would add your telegram handle here and promise $200 for information you can easily google, all these looks suspicious.
Worth knowing that $8000 should be kept on a cold wallet or cold wallet setup eith multisig wallet. Using cex account keep your coin not actually advisable. You can use it and to purchase any coin you wanna purchased and send them in any Dex account. Because leaving your funds in cex account is like leaving your funds on someone else's hands.
There are various good bitcoin wallet you can store your asset we have.
Electrum
Bluewallet
Exodus
Mostly electrum is pretty great and also do your research about them too. And you don't have to pay anyone here for asking for help. Because one of the aim of the forum is to render help to those who need any assistance. Because here you can meet alot of pro.
Exodus is a close source wallet. Not recommended at all. Online wallet also not recommended unless you use them as a cold wallet on an airgapped device. I’m thinking OP may be a scammer. It’s unlike that someone would want to gift a stranger $200 for doing next to nothing. For the more trusting members of the forum, remember that there is no free lunch in this world. If it sounds too good to be true, it is not real. Anyone who is greedy enough to pm that telegram account will surely be roped into a scam.
I guess so as well. He may likely be a scammer |

First of all, be careful of scammers. The person might give you a link to download a fake wallet and if you import your seed phrase on the wallet, all your coins will be gone.
I do not know what could have caused this, but hope the transaction is not more than 100 kb? If the transaction is too larger, Electrum will not be able to broadcast it.
If you have the desktop version of Electrum, you can import the seed phrase on it because this kind of complaint I have seen in the past was from mobile Electrum user, but it was about transaction signing through QR code and not address.
You can also try to use Sparrow wallet and see if it is going to work.

Therefore I would prefer to use the newer EFI systems over BIOS to set up an airgapped system.
It is true that UEFI has better security. Also it has faster boot time as I noticed 7 second boot time in the Windows computer that has it, unlike legacy BIOS. Recently made computers are using UEFI and not the the legacy BIOS which people called BIOS. Or maybe legacy BIOS is still used on low budget computers. But if you have an old computer that make use of legacy BIOS instead and you need a cold wallet, that means you will not use it? If my old computer is using legacy BIOS, I will still format and reinstall the OS and use it as cold storage wallet hardware for bitcoin and I am certain that nothing will happen as long as it remain as cold wallet. But I will appreciate your sincere answer if you will use the old computer with legacy BIOS or not. It is worth knowing that the old BIOS is referred to as legacy BIOS while the new BIOS is referred to as UEFI or EFI. UEFI is still Basic Input Output System (BIOS). |

All you have to do is send the dust to the Genesis block address, something like 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa which will never move their coins or have outgoing transactions, so the attackers can have run watching a rock just sitting there.
Sure, it will cost a few sats in fees if you want the thing to be actually confirmed, but it's worth getting rid of such parasites from your wallet.
Yes the fee is high. Dust coin can be as low 294 sat for segwit addresses. The network has not been less congested down to 10 sat/vbyte since a long time ago. Right now it is over 50 sat/vbyte for low priority. For 1 input and 1 output segwit (bc1q) transaction, the vbyte is 110. With fee rate of 10 sat/vbyte, the sat to pay is 1100 sat. The mempool isore congested and I do not think this is really worth it to spend the coin. I prefer to tell people to give it to charity or using a mixer for it, but that was when the transaction fee is very low. I may just prefer to empty the wallet with necessary transactions and leave the dust coin. If it is finished, I may delete the wallet. Or if the transaction fee is low, I will send the coin out of the wallet address instead. |

If you want to explain about dust attack, you should know that you need to explain about coin control. You only included in your post that the dust coin should not be spent. There are just few wallets that has coin control. Examples of wallet with coin control are Bitcoin Core, Electum, Sparrow, Bluewallet, Samourai and few others.
The best is to just use coin control to freeze the dust coin.

The old ASICs with lower wattage consumes power than the new miners with high wattage. You can read about old miners like Antminer S9. It is generating 14 Th/s with 1372W power consumption. You can not compare it with Antiminer S19 Pro+ Hydro cooling that is generating 191 Th/s with 5252.5 watts. The wattage is higher but lower in comparison with the hashrates generated.
As for the ones with 300-600 watts, no device of this power consumption will be able to mine bitcoin profitably. GPU might have this lower power consumption, but not ASICs.

No, you can not mine bitcoin with CPU. Even you can not mine bitcoin with GPU, not to talk of CPU. To mine bitcoin, you will need ASIC. You can visit Bitmain website that are creating Antminers to see some of their products. I will recommend at least S19 Pro that is generating at least 100 Th/s or other ASICs with higher hashrates generation.

Before full RBF was implemented, merchants and some people were accepting unconfirmed transactions as long as the sender uses high priority fee that were enough to get the transactions confirmed in the next block. But when full RBF was implemented, transactions that do not support RBF can still be replaced, that is the reason this is no more a viable solution to make bitcoin unconfirmed transactions to be accepted.
I have accepted unconfirmed transactions before but I can novmore accept it because of full RBF. You have no option than to wait for at least 1 confirmation. If the money is huge, wait for more confirmation.

I wish this not to be true. A true hero is leaving us. I just wish it not to be true is my wish. I will really miss you. I can never forget you because you are one of the people in life that I gained knowledge from. My staying on this forum has taught me enough lessons in life and you have been one of the members that was helpful. It is said to see something like this.

This is an old common crypto scam. But probably some newbies can fall victims of it. If we should take a look at it, when you generate a wallet and want to backup the wallet, a reputed wallet will warn you that the seed phrase must not be lost, else you will lose your coins. They clearly state that and some will also states that if anyone sees the seed phrase that the coin can be stolen by the person. I am always surprised if anyone can click on a link and input his seed phrase on a website. That is foolishness to an extent.
|
|
|
|
So my question is, is there any possible way of sending all the transactions out as one output to a new wallet in order for it to be smaller in size and the transaction fee to be lower?
Be patient and hope that mempool high fee priority can get as low as 1 to 2 sat/vbyte again. |

5000 transactions paid to pay-to-taproot addresses. That is 287556 vbyte in total. You can only send 100000 vbytes max in each transaction. That means you will need a wallet like Electrum or Sparrow that you can be able to use coin control and split the transactions into 3 so that you will be able to send it.
To be able to do this, it would be better for you to wait until the mempool is not congested at all as AB de Royse777 posted already. In this kind of transaction, 1 sat/vbyte is the best.
The mempool was not able to go more than 2 sat/vbyte in November when it was less congested, maybe this can be possible again but let us see. Just wait.

2. People trust CEXs more because they've been around far more than DEXs. With CEXs, at least they can go after someone should worse comes to worst.
This is not one of the reasons. I do not even know the one that have been existing before another. Trading volume on centralized exchanges are far greater and people like to use something that government approved. Centralized exchanges looks more like brokers in Forex and people like such a thing as they abide to anti-money laundry and counter terrorism financing. People are ignorant and prefer what government move towards to. |

Always backup your seed phrase because it gives you access to your coins. It is important than Electrum, Trezor or any wallet that you used for spending your coins.
Do the firmware update and make sure you also update Electrum and see if you will be able to have access to your coins just as OmegaStarScream posted already. I think you should still be able to have access to your coins.
If it is trezor One or Trezor T, likely the physical means of revealing the seed phrase would be the last resort.

My major setback now is the high transactions fees and congestion in the mempool but I've made provisions for my BTC Address to customers but for now they're still patronizing me in fiat.
You opened a bar. A bottle of beer is not up to $1. 1 input and 2 outputs bitcoin transaction at 80 sat/vbyte cost 4.79 in fee. We all know that it is not possible to pay using bitcoin onchain transaction for some beers. In Nigeria, naira is more used for payment and using bitcoin is getting more discouraged with the high fee. Although, there are expensive drinks and wines, but fiat transaction locally is instant and of very low cost. On Opay, Kuda and Palmpay and some other means of paying for goods and services, the fee charged for some number transactions per day or per month are free. |

Before Kuda, OPay, Palmpay are known, you will still notice gradual improvement in commercial banks. I can remember vividly in 2014, that all failed ATM transactions on my card were all reversed, unlike some years before that you have to go to bank and complain to customer care. Although, there might still be failed ATM transactions but it reduced.
The failed transactions that was common around that time were online ones made on devices and which is still a problem today. It was common during the naira scarcity. Sometimes, the payment might be successful, but no notification. It depends on the bank that you are using. I do not have the problem with the bank that I use.

You can not buy crypto through bank directly. I just want to make this clear because banks are not allowed to get involved directly with bitcoin and other cryptocurrencies. But what you are talking about is buying through payment processor like Visa, MasterCard, JCB et cetera.
Lifting the ban makes it possible to buy cryptocurrencies through payment processors like the ones I mentioned above. I have tried it before and it was fast. But after the CBN ban, I have not tried it and I am not ready to try it anymore as I now prefer P2P. Only what is important is that I should avoid P2P scam.
