Do you really think is it worth to do all this effort, instead of just buy a hardware wallet because you want to customize?
The key here is safety, and for now the hardware wallets are one of the best methods available and it's simple
I believe my 1 btc will be worth $100,000 in 10 years. So, I don't mind having to do all that work if I have to. Just for the sake of education, would you disagree with me that the wallet method I described is less secure than a Ledger nano S? If you do disagree, can you explain why? Thanks.
