Hi
I mined bitcoin from 2009 till about 2011, latest bitcoin used 0.3.24 july 2011
Never did anything with the wallet starting with a 3 and a private key.
Can I just import the key in trezor suite?
Or should I use bitcoin core to import? sparrow wallet? and sweep it to a btc1 adres what my safe 5 makes?
I have the 700gb that bitcore downloaded to use as a node, or should that be electrum?
You can’t import private key to trezor.
Unless your wallet is itself already a 12 or 24 word seed phrase, the usual format (raw wif private key) is not compatible with what Trezor is doing.
So what you can do is you setup your Trezor, and you send BTC from your old wallet to your Trezor.
