You can either import or sweep your private key(s) into electrum.

If you import your private keys, you don't make any transaction and you will have access to the same wallet in electrum.
Sweeping means creating a new wallet in electrum and send all the fund to the new wallet.

Sweeping may be safer because you will send all the fund to a new wallet.
If you import your private keys, you will have the same keys in two different wallets and that may increase the number of  attack vectors for hackers.

Take note that any online device is prone to hacking and if you want to be completely secure, you should import your private keys into an air-gapped device. That's highly recommended, especially if you have a big amount of bitcoin. If you do so, your wallet on the airgapped device will be used only for signing transactions and you will need a watch-only wallet on an online device for checking your transactions, creating unsigned transactions and broadcasting signed transactions.



Bluewallet is also good.
For desktop, I prefer to use electrum.

You need bitcoin core and the full blockchain if you want to make transaction with Armory itself. With having the full blockchain and using Armory, you won't rely on servers run by third parties and that's helpful for protecting your privacy.

In the case you are going to make transaction with Armory, make sure that pruning is enabled in bitcoin core.
To check if you are running a prune node, click on "Setting" at top of the window an then go to "Options". If you run a prune node, Armory can't be synced and you will have to redownload the blockchain after disabling prune mode.

If you don't want to download the blockchain, you should export your private key(s) and import them in a SPV wallet like electrum.
For exporting your private keys from Armory, you don't even need internet connection.

First create a wallet in Armory using your paper backup, if you haven't already done so.

To know how you can export your private keys, click here and follow the guide provided by HCP in another thread before.

After exporting your private keys, you can import them in other wallets and spend your fund. A good option is electrum.

So, you have successfully broadcasted a transaction with 30 sat/vbyte.

Now some nodes have the transaction paying 30 sat/vbyte in their mempool and some nodes have your first transaction in their mempool.
Since ViaBTC doesn't accept your transaction, it means that they still have your first transaction in their mempool.

Unfortunately, the network has become more congested and even 200 sat/vbyte isn't enough for getting confirmation now, let alone 30 sat/vbyte.
If you are in a hurry, you should bump the fee.


It doesn't matter what address you used.

Rebroadcast or broadcast?

You said you removed your transaction from electrum and your balance reappeared.
What did you do after that? Did you make a broadcast a new transaction using electrum? Since you have removed your transaction from electrum and the node you are connected to doesn't have it in its mempool, you should be able to make a new transaction and you shouldn't get any error.

If you removed your transaction from your electrum wallet, you can make and broadcast a new one using electrum itself and you don't need other tools like coinb.in for that.
Also note that even if you have broadcasted your new transaction, it's possible that ViaBTC doesn't have it in their mempool and still has your previous transaction.

Thanks for your information, but I said the same thing above your post and I edited my first reply 13 minutes before your post.
My point was that it's not possible for an average user of bitcoin to make such spendable output.

Here are some more transactions creating outputs worth less than dust limit.

Transaction 1
Transaction 2
Transaction 3
Transaction 4
Transaction 5

Yes, you have to redownload the entire blockchain.
Every time you import a new address/private key or a new wallet in bitcoin core, it has to rescan and that's not possible if you are running a prune node and you don't have the entire blockchain.

Note that there is no way bitcoin core can know when your address was first used without having access to the entire blockchain.

Consensus rules allow creating an output worth less than the dust limit and you are right. I said that's not possible because such transaction would be non-standard and would be rejected by nodes.

Thanks for your correction. I edited my previous post, so that it's more accurate.

If you run a prune node, you can check only your own transactions and if you import a new address, you have to redownload the blockchain.
If the purpose is to check any transaction without relying on third parties, a prune node wouldn't be helpful and you would have to run a full node.

Zero value transfer? Do you mean a transaction sending 0 BTC? That's not possible at all.

You can't make a bitcoin transaction creating outputs worth less than the dust limit.
The dust limit is 546 satoshi for legacy addresses and 294 satoshi for native segwit addresses.

Edit:
A transaction creating an output worth less than the dust limit is valid, but that's not standard and would be rejected by nodes.
Thanks BlackHatCoiner for the correction.

As I ready said by others, there are many block explorers that can be used to check if a transaction is valid.

Just take note that being valid is not enough and you should never accept an unconfirmed transaction. It's possible that a transaction is now valid now but unconfirmed and becomes invalid after a while.

Many nodes have already dropped OP's transaction from their mempool.
At the time I am writing this post, according to mempool.space, the purging fee rate is 15 sat/vbyte. This means that any transaction with the fee rate of less than 15 sat/vbyte is purged from mempool of any node with default mempool size.

OP's transaction has not been flagged as RBF which means that's not supported by ViaWallet and there shouldn't be any option to increase the fee in the wallet.

Of course, as I said in my previous post, there are many nodes that have dropped OP's transaction from their mempool and should accept a new transaction with the same inputs. 

The fee rate used for your transaction is below the purging fee rate for any node with default mempool size. Therefore, there are many nodes that don't have your transaction in their mempool now.

Import your wallet to electrum. There's a change you don't see your unconfirmed transaction and you can make a new one.
If you see your transaction in electrum, try connecting to different servers until you find a one that doesn't have your transaction. Once you connect to a node that doesn't have your transaction, your transaction status will change to local and you can remove it from your wallet using right-click menu and then make a new one.

Download electrum only from its official website.

You are right.

I don't know.
I think any wallet that supports coin control should allow spending unconfirmed coins and that's why in my previous post I said your statement is true. 

My point was that if you can spend unconfirmed coins, you can do CPFP manually without coin control.

The ID of the transaction OP is talking about has been already posted in this thread and you could check that to see if he/she is right.
What caused the transaction fee to be that high has been also explained, but unfortunately you don't read the replies.

The block size can be bigger than 1 MB. The maximum limit is 1 vMB or 4 million weight units.


With using segwit addresses, you decrease the virtual size of the transaction and the weight units.
Take note that with using segwit addresses instead of legacy addresses, your transaction size wouldn't change significantly and it's even possible that you increase the transaction size.

Transaction fee doesn't depend on the amount you send. So it's not a percentage of the amount.
The transaction OP is talking about includes 53 multi-signature inputs and that's why the fee was that high.


You could know more details about the transaction, if you had read previous posts before making a new reply.

Please read previous posts before making a new reply.


As you said, that chart is displaying the average transaction fee.
Depending on number of inputs and outputs and addresses types, the total fee required to be paid for a transaction can be different.
