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.
Look, leaving clues about the remaining words and not having them written down anywhere makes your money safe, sure. But what if you somehow forget the words, stop understanding the clues? Then your investment is lost forever. And it might be that the probability of you forgetting the words is higher than your wallet getting hacked. I use 2FA and I feel pretty safe. There are a confirmation link on my email address and a temporary personal code sent to my phone. Oh, and also a password which is a mixture of words and symbols. The password is stored in a way I find secure. There's a chance that it can be stolen and hacked, but the chance is low, and I am okay with that.
