Was going to try Electrum - downloaded Electrum portable
Take note that since you've downloaded the portable version
Your Electrum data directory (
electrum_data) will be saved in the same folder where "
electrum-<version>-portable.exe" is located.
It's meant to be used in removable storage like portable HDD/SSD or USB flash drives.
If you meant to use the standard executable without requiring installation, download the "
Standalone Executable" instead.
OR any other wallet suggestions that will not require a long duration to download before I can send my bitcoin to an exchange?
Doing the "
sweep" method above will incur an on-chain transaction that will send it to the newly created Electrum wallet.
(
once you arranged the provided instructions in the correct order, you'll get it right, it's not that complicated)
Since there's a transaction, it will require a transaction fee to send from Bitcoin Core's exported key to Electrum,
Then another transaction, another fee to send from Electrum to Exchange.
If the goal is to keep some bitcoins to your new Electrum wallet, I'd also recommended it.
But if you only want to send all to an Exchange, you can import it to a new imported Electrum wallet instead, then send max to that Exchange.
With that, you can import it by creating a new wallet in "
New/Restore->(Wallet name)->Import bitcoin addresses or private keys".
Paste your WIF private keys there, click "
note" for the necessary prefix in case the address(es) aren't legacy.
After creating the imported wallet and letting Electrum sync, you can now send with max value to your Exchange Deposit address.
