unconfirmed transactions – How can I send less than 0.001 BTC from my Bitcoin Core Wallet

I recently managed to recover my wallet.dat and passphrase and have been trying to send the 0.00126913 BTC balance from my Bitcoin Core wallet into my Binance account, however the transactions stay unconfirmed for several days with no luck.

I’ve tried enabling ‘coin control features’ and sending 1-3 amounts at a time, however still no luck.

Is there anything I could do to increase the chance of my transactions being included into a block?

wallet – How does public address “know” private key?

Imagine the following:
someone goes to the .org address of bitaddress, then switches off internet connection, then moves the mouse around until eventually the JavaScript Client-Side Bitcoin Wallet Generator produces a Bitcoin address with its corresponding Bitcoin private key, then saves everything on the screen to cold storage as a PDF, then scans the “Share” QR code onto a phone, then scans this QR code at a Bitcoin ATM to purchase Bitcoin and the Bitcoin in deposited in the wallet and this is confirmed on blockchain.
If later wanting to sell the Bitcoin, how does this public Bitcoin address “know” what the correct private key is?
That is, if the Bitcoin public address and private key have only existed on a non-internet connected PC and as a PDF in cold storage?

Bitcoin Wallet Crash Report – Bitcoin Stack Exchange

I was into bitcoin back when it started years ago, but over the years I got busy with other things and forgot about it until all the recent news. I was able to locate two emails from 2011 notifying me of Bitcoin wallet crash report. I think that was about the time I also switched phones from android to apple.
The below info is what’s in the email sent to me. Will I be able to retrieve my wallet info from the information in this email? If so, please explain how I can access this wallet again. Information listed as (XXXXX) is identifying information I have left out of the email chain log. Thank you in advance for your assistance.

security – Is our hardware wallet safe if the PC or Mac has 3rd party apps?

For example, our PC or Mac might have 3rd party apps installed, such as Pixelmator, GIMP, or VLC player. They are usually considered to be safe apps.

However, is it true that when using a hardware wallet, we need to use the PC or Mac, and if the PC or Mac is hacked or is affected by any 3rd party software, then our private key can still be stolen? How do we prevent it from being stolen?

Having said that, I heard that if we did not install the app as an admin on the Mac, that is, if we installed the app only by dragging the app into the Applications folder, then we can reboot the Mac and not run any 3rd party app, and at this stage, no 3rd party app should be able to do anything bad. If we installed the 3rd party app as admin (root), then it is a different story because now the app can be running itself or a small component in the background even after a reboot.

wallet recovery – How can I check if my seed matches a BTC address?

I have a seed with 12 words from Coinbase Wallet. The derivation path is: Segwit Native (p2wpkh) m/84'/0'/0' BIP84.

The first address generated seems to be wrong because it does not get generated anymore.

I can’t get access to the funds with Electrum and a gap limit of 10000.

I’m sure that the address contains my funds and no other transactions than my initial are visible in the blockchain explorer.

How do I do get access to that address?

Can this be somehow brueteforced or something?

bitcoin core – How wallet handles different cryptocurrencies?

As far as I know, wallet stores private and public keys and calculate balance according to that.
Suppose a wallet(Single cryptocurrency) has 3 keys (private,public). Wallet will find UTXO’s connected to those keys and display balance on your wallet UI.

But if a wallet handles different cryptocurrencies, how does it distinguishes between different cryptocurrencies? How does it know available public address belongs to a particular currency (Blockchain)?

wallet – Can not find or remember exchange

About 4 years ago i gave my son some BTC for his Birthday….
Trying to teach him a bit of financial responsibility…..
he created a wallet, on an exchange i believe, i wasnt part of that, as i insisted he take charge and responsibilty for his own, and, keep passwords, seed etc safe.

Fast forward till now….. He can not remember which exchange he created the wallet on, i do have the original wallet numbers however…… dont have seed.
it there anyway to tell which exchange it went to , he ” thought he saved all the info on his computer….. kids huh.
