is remembering 12 words that hard?
Exactly, lol. I would rather prefer to remember my seed phrase than write it down and have all my money stolen at some point in the future. Or just sit on the piece of paper, trembling that someone might see it. It's all so troublesome. Why not just remember it? Its only 12 words.
And anyone who has a bad memory could use the 12 words to enter their wallet each and every day. After doing that exercise for a while, they would reach some point where their brains store their seed phrase in their long term memory.
It does not even have to be every day. You could enter your wallet through your seed phrase every few days. It would still commit itself to your memory after a while.
But you are still in danger of keyloggers and the sort... So is there really a 100% safe method? Not really.
