These parts from that guide is quite dangerous:
For example
p2wpkh-p2sh:5BitcoinPrivateKey
This should generate the corresponding p2wpkh-p2sh bitcoin address.
p2wpkh:5PrivateKey
This should generate the corresponding Bech32 address
Using uncompressed keys to generate SegWit addresses will lead to loss of funds.
Although new versions of Electrum (
old versions does) and most wallets wont allow it, it's better not to use uncompressed keys (
starts with '5') as an example.
I usually don't want to waste time in complicated Bitcoin wallets normal wallet is enough and I much confident with Blockchain wallet than other wallets sorry if My perception is wrong to you.
Electrum is as complicated as "
blockchain" online wallet.
Actually, when it comes with restoring from seed and other recovery procedures, blockchain is more complicated.
