Hi, I read here a lot, but do not speak much. This thread has the majority of advanced users, so I am asking here...
I have used public/private keys, generated locally offline from the code at
https://bitcoinpaperwallet.com (public key starts with a 1).
I wish to move them to a segwit paper wallet (public key starts 3), I understand there are technical advantages (cheaper miner fees?). What's the best way to generate offline segwit key pairs? I found
https://segwitaddress.org/ but have no experience with it.
Then, I assume I should just sweep them into a local wallet (I prefer Electrum), then send them to the new segwit public address. Suggestions or advice?
Create a new wallet with Electrum. Consider using a hardware wallet with Electrum if the value is high.
Write the seed words down and store them in safe place.
Then import your old wallet into Electrum.
Send your BTC form the old wallet to an address inside your new wallet.
