Leave your seeds phrase in one place is dangerous to crypto users, because there can be fire incident or water incident that will make your house or room be flooding with water to condemn the paper or laptop you saved the seeds phrase. If you write them down in different places in different house's, I guess it will be more safer for future purpose.
You are not supposed to store your seed phrase on something that is susceptible to fire or water damage. The metal seed storing options solve this issue. There are only two other issues. One is massive environmental disasters, a flood that would actually carry away your house and the backup. The second is that someone could find your backup since everything is in one place. The following is true for diligent and responsible people: The chance of someone discovering your seed phrase and stealing it is always higher than you losing one or several pieces.
The most important information to keep dear is that the essence of using seed phrase is to protect against hackers, malware and physical damage like fire, water or loss.
A seed phrase backup does not protect from "hackers". A seed phrase can't be "hacked". There is nothing to "hack", it can only be discovered (randomly or stolen with intent) or guessed (randomly).
Don't split your wallet seed words, it's very risky.
No, it is not.
You can store your wallet (mnemonic) seed words in each full wallet backup, but make multiple backups and store them at different locations. You will only need to have access to one of your wallet backups at one of locations for recovering your wallets.
If only 1 location is discovered, you lose everything. More locations = higher probability that 1 location is discovered, since multiple exist. You dismissed a good thing and gave even worse advice instead. Sweet irony.
Splitting is a general term that covers a range of behaviors. Sharding the seed is also a form of splitting.
But isn't splitting the recovery seed in several places too troublesome? I don't know about others, but for me, doing something like that is quite troublesome.
No, it is the gold standard of security. Usually what would be done is a multisignature address where keys are held by different people and at different locations. It is very similar to good forms of seed splitting. Anyway a general assumption can be made that if more than 1 location of yours is compromised at any time (2 pieces) then you have terrible security practices. For the average person, this should basically never happen. It is more likely that 1 piece is compromised by chance, e.g., the whole place where one piece is stored got robbed.
I prefer to put all the words in one place and I use my brain to remember my seed phrase.
This is not recommended. First, you will forget it. Second, if you know it then someone can torture it out of you. If you don't know it, no amount of torture will help.
