From bitcoin newest source, how can I set transaction fee as more lower?
Some wallet(ledger nano hardware wallet) even provide now custom transaction fee, how is possible?
If you possess the private key of your address:
- Import it to a wallet like Electrum or Bitcoin Core
- You can then use the "Send" feature and add "Address" in the address field, "BTC Amount" that you wish to send and at last, you can use "Custom" in fee to choose what are you willing to pay for that transaction.
