Yes, it is possible to scan multiple addresses simultaneously with your own node using the scantxoutset command in Bitcoin Core. Instead of querying each address independently, you can provide a list of addresses as an argument to the command.

Here's an example of how you can scan multiple addresses simultaneously using the scantxoutset command:



Replace addr1, addr2, and addr3 with the addresses you want to scan. You can add as many addresses as you need, separating each address with a comma.

By providing multiple addresses in a single command, you can save time and speed up the scanning process.

Yes, it is possible to link addresses together and determine if they come from the same wallet or seed. This can be achieved through various methods, including on-chain data analysis and transaction graph analysis.

Here are a few techniques that can be used to link addresses:

1. Common Input Ownership: When multiple addresses are used as inputs in the same transaction, it suggests that those addresses belong to the same entity or wallet. By analyzing transaction inputs and outputs, patterns can be identified to link addresses together.

2. Change Addresses: Many wallets use change addresses to improve privacy and security. When a transaction is made, the change is often sent back to a different address within the same wallet. Analyzing the change addresses and their relationships to other addresses can help identify common ownership.

3. Cluster Analysis: By analyzing transaction patterns, such as common spending habits or recurring transaction flows, it is possible to group addresses together into clusters that are likely controlled by the same entity or wallet.

4. Heuristics and Metadata: Some analysis techniques involve using heuristics and metadata associated with addresses, such as IP addresses, transaction timestamps, or known wallet behavior. These can provide additional clues to link addresses together.

It's important to note that while these techniques can be effective in certain cases, they are not foolproof. Privacy-enhancing techniques like CoinJoin, mixing services, or using separate wallets can help mitigate the ability to link addresses together.

Additionally, newer technologies like Hierarchical Deterministic (HD) wallets, which generate a new address for each transaction, can make it more challenging to link addresses together.

No, you cannot directly obtain a wallet's seed phrases or private key just by having the wallet's seedQR. The seedQR is typically a QR code representation of the wallet's seed phrase, which is a mnemonic phrase used to generate the wallet's private keys.

To recover the seed phrases or private key from a seedQR, you would need to use a compatible wallet software or tool that can import or scan the seedQR and derive the seed phrases or private key from it. This process usually involves using a wallet application that supports the specific seedQR format and following the necessary steps for importing or scanning the seedQR

Yes, there is a tool called "Electrum Recovery Tool" specifically designed for recovering the private keys from seeds generated by Electrum. This tool is similar to iancoleman's BIP39 tool but is specifically tailored to work with Electrum's seed format.

You can find the Electrum Recovery Tool on GitHub at the following link: https://github.com/3rdIteration/electrum-recovery

Please note that when using any tool for recovering private keys, it is important to exercise caution and ensure that you are using a trusted and secure environment.

It is difficult to predict the future movement of Bitcoin prices with certainty. However, based on the historical patterns and the upcoming "halving" event, there may still be potential for significant returns for investors. The previous halving events have resulted in bull runs and increased prices for Bitcoin. Therefore, it is possible that the current price gains could lead to another surge in the value of Bitcoin. However, it is important for investors to carefully consider their own risk tolerance and conduct thorough research before making any investment decisions.

To move/update your wallet.dat file from an old desktop to a new computer, you can follow these steps:

It's important to note that if you had any transactions after the creation of the wallet.dat file, those transactions might not be visible until the software finishes synchronizing with the network.

Remember to always keep a backup of your wallet.dat file in a secure location. It is also recommended to encrypt your wallet and use a strong password for added security.
