If you keep multiple seed phrases in one place, what's the point of using multiple wallets to store bitcoin? I'm not saying that splitting bitcoins into multiple wallets is not safe but it will also have disadvantages because having to keep multiple seed phrases safe is not easy. Furthermore, if you are sure about your security, why would you need to store bitcoins on many different wallets? Unless you don't trust your ability to protect your seed phrase and how you keep your assets safe.
You've got the wrong idea mate. You don't just put your seed phrase directly on a piece of paper or whatever you are using in order to store your seed. You use some kind of
encryption before you do it. Here's an interesting method I have come up with. There are 12 or 24 words in a seed phrase based on which one you choose. Now you can divide them into 3 or 4 parts. That being 1 2 & 3 or 1 2 3 & 4. In each of those groups, you put the same amount of words (this is for a 12-word seed phrase). Each group can have 3 or 4 words based on your choosing. Then you can randomize them to get a number. For example, it could be
3412. Now you put as many random words as you want between each number. But the number of new random words should be the same. For example, if you want to put 4 words before the number 3 in the group of
3412, the number of new words after 3 4 1 and 2 should be 4 words as well.
like this
RW= Random Words.RW RW RW RW 3 (
contains the actual seed) RW RW RW RW 4 (
contains the actual seed) RW............................RW
[it goes like this until you have a full list of random words.]
Then you can make as many copies as you want and trust me, it is gonna take months for hackers to crack this.
(if they get a hold of your word list in the first place.)All you need is
the word list, the
amount of random words you put in between and the
actual number after randomization. For Example
3412. You first make sure even if someone gets their hands on the seed, they won't be able to crack it. Then you make backups. That's how I do it.
[Not exactly the same method but something else that I am not going to disclose publicly.]But yeah. Having multiple seeds in one backup is not an issue if you are able to encrypt it. ALso, you can add some dummy accounts in there as well. You know the formula so you can check all the accounts, but for hackers, it will be a nightmare.
