There are many of them. Example are Unstoppable, Mycelium and many other wallets that support altcoins. In fact, I have not seen an altcoin wallet that is supporting bitcoin that has this (RBF) feature before.

Import the seed phrase into wallet like Electrum, wait for one of the servers to drop the transaction from the mempool. If you have waited for 2 weeks and you did not see the coin on Electrum wallet balance, change the server from automatic to manual and select the servers one by one and synchronize the Electrum wallet each time you change the server. You can even do it before 2 weeks daily and repeatedly until you see your coins.

If your coin have appeared on Electrum balance, you can spend the coin again on a new transaction.


There is also option of full RBF in a way you can use a node/server that supports full RBF to rebroadcast the coin. Electrum: how to use Full RBF?

I think this kind of question was asked some weeks ago. You can not generate vanity address using seed phrase. Although, it is possible, but there is no known available tool that you can use to generate it.

Edit:
This is the thread that I am referring to: Mass BTC Wallet Generator with mnemonic andbip39. You can go through it and see some people's reply.

This is not true. Make use of P2P and bank has no charges to take than the normal transaction fee.

Nigerians are not allowed to trade on Coinbase. It would have been one of the most popular exchanges in Nigeria. But you know the type of segregation we faced from many services from United States like PayPal. Coinbase is one is them. Thankfully, we have alternatives that we can even say are good and better.

There are other better centralized exchanges as well. You can look for their trust score on some sites like Coingecko.

People are the problem themselves. The world has been the hottest this year while bitcoin miners are producing less carbon dioxide than what critics depicted about bitcoin in comparison with the total gases release to the environment that can cause global warming from tiger human activities. The reason the world is getting warmer day after day is not because of bitcoin mining but because of how the world are generating electricity, industrial chemicals released to the environment, deforestation and transport emissions of the gasses that can cause global warming.

If you continue to open your wallet, the wallet will synchronized with the blockchain again and likely the server the wallet depends on will continue to rebroadcast the transaction. If your transaction is stuck, it is better not to open the wallet, or making sure the wallet do not synchronize with the blockchain. With this, if you import your seed phrase or private key on Electrum, with time, a server or some servers will drop the transaction from their mempool so that you can rebroadcast the coin again in another transaction. I have seen people that used Coinomi, Mycelium and Trustwallet that import the seed phrase on Electrum and were later able to rebroadcast their coin again.

You meant Metamask wallet. Second is that someone should not hold huge amount of coins on an online wallet. If the amount of coins is huge and also for many coins and tokens, the best is to get a hardware wallet. One of the best hardware wallet that can be gotten is Trezor. Trezor is supporting bitcoin and many altcoins.

Although, if it is a bitcoin only wallet, Electrum can be used as a cold storage wallet. Also is Sparrow and some other reputed bitcoin wallet.

Elon Musk manipulative tweet that Tesla is no longer supporting bitcoin for paying first crashed bitcoin price. Later the Chinese crackdown on bitcoin mining later crashed the price to less than $30000 before increasing to all-time-high. Something like this can also happen in the next bullrun, there are some negative news that can significantly crash bitcoin price in some minutes to hours. But the later long-term outcome is still all-time-high and bullrun.

The best you can do is to go for hardware wallet like Trezor.

Exodus is a close source wallet.

Unstoppable wallet is open source but it is a mobile wallet and not having a Desktop version. OP is looking for a desktop wallet and all the ones that I know are close source except bitcoin wallets that we have many open source ones.

I thought that you can brute force such a wallet. Or have you forgotten you have a topic that you can recover such a wallet. This from one of your topics in the paste as reference:


So recover the wallet yourself than to sell it. You will not be able to recover the coins because you are only looking for someone to scam.

You can use Electrum on an airgapped device.

Do you mean private keys or public keys? On Electum, you can have access to the private keys and public keys that your seed phrase will generate.

Do no mind my question. Why is public key so important that you want to generate it and not mentioning private key? Know that private keys are needed for spending your coins and not public key.

Theymos needs to give us off-topic board.

Testnet may be useful for beginners, but I did not know what testnet is since I have been using bitcoin until I can came to this forum to know it exists. This makes me think that most beginners are not starting their bitcoin journey with the use of Testnet. Testnet will be mostly useful to the developers that will first make use of Testnet before introducing a new protocol to the mainnet. Also it would be more useful for wallet developers.

Do not use close source wallet. Do not use Javascript to generate your seed phrase and private key. Do not use a brain wallet. Avoid those with insecure means of generating seed phrase like Libbitcoin explorer. These are all insecure means of generating seed phrase and private keys.

Use a good software to generate your seed phrase and private key. Go for reputed wallets like Sparrow, Electrum, Trezor etc. There are many open source wallets for bitcoin that are reputed that you can go for.

If you generated your seed phrase and private keys securely and safely on a safe device like airgapped devices, the 128 bits of security that bitcoin has is still enough against brute force attack.

These are some sites you can be helpful for you to collect some testnet coin: List of Testnet BTC Faucet

If you want to return the coin after you finish using it, I think NotATether and BlackHatCoiner have their thread for it. Go through their topic history or message any of them for help.

The difference is that lightning network is not as secure as bitcoin on-chain network. Also that you can not use the lightning network for transactions huge in amount to save fee. Lightning network wallets has to be online while you can transfer bitcoin onchain while using cold storage wallets and other secure means. For security reasons, you still have to depend on bitcoin blockchain.

Many people from all over the world with different time zones are on this forum. If you want to talk about something like this, you will need to specify your country time zone. The morning in your country is the afternoon or nighttime in another country.

Trading is not as easy as this at all. Bitcoin do not have a time it will increase it decrease. You may notice what you are saying to be repeating, but within some days, it will change. Bitcoin may increase during the day and fall during the night. Bitcoin may increased in the night and decrease during the day. There is not specific time for the increase and decrease of bitcoin price.

That was so nice of Satoshi Nakamoto. If bitcoin is like monero, it might also not be widely used as it is today. Nearly all countries do not ban bitcoin and the discovery mechanism would be one of the reasons many countries do not ban the coin.

Exactly. But it is worth knowing that fiat is mostly used for illicit activities today. It is mostly used for money laundry, terrorism financing, ransom and bandits funding etc. So far something is of value and can be easily transfer from one person to another as a money, some people will want to use such thing for illicit activities.

Good contribution. Well done.

I think you have a thread that you can use to notify people about this: 16 Bitcoin Software Wallets, compared feature by feature

This thread is mainly for wallets that are generating pay-to-taproot addresses and not a comparison thread.

But if you see a reputed wallet that is supporting pay-to-taproot and not yet included on the OP, you can post them here at anytime so that  dkbit98 can edit the OP and include the wallet if necessary.

There is a thread about it on this forum already since yesterday: https://bitcointalk.org/index.php?topic=5484294.msg63622206#msg63622206

For maximum security, one of the best option is to go for a wallet on an airgapped device which its OS has been reinstalled and also making sure that it is not connected online by removing its WiFi card. Also remove the Bluetooth. If a wallet is setup on the device with the seed phrase having a strong passphrase is a good option. Backup the seed phrase and disable the USB ports and card reader or something from the Bios.

Another option is a 2-of-2 multisig in a way at least one device is a cold wallet like hardware wallet. Or going for a 2-of-3 multisig in a way that at least one device is airgapped. Better security but transaction fee will be high. Better for storage. For a wallet that is not used frequently.

For small amount on a desktop or a mobile wallet. Do not use the device to browse anyhow you want. People are now having at least two phones, and a laptop if possible. I prefer to use just one of my phone for browsing, while the other phone for just something related to wallet and exchanges. Disable download from unknown source. From settings, disable apps not to download files. Do not use it to download anything and also not using it for browsing. Just use it for only wallet and exchanges and let your other phone do the other work and get be careful of malware on the two devices. Do not share files with the devices.

Leave small money on online wallets while the remaining on cold wallets.
