Multisig Fund Protection Strategy Review

I want to protect my bitcoin and mine Threat model It’s about accessing one of two paper copies of the seed, collecting your wallet and stealing your funds. To mitigate this risk, we are considering the 2-OUT-3 multi-sig wallet option. My first strategy is:

Therefore, I have four geographically separated secret locations (except for myself). As for hardware wallets, if your main device is stolen, you need another key, which means Bitcoin is safe. The same can be said when location 1 or 2 is discovered and the hardware wallet device is stolen (as there is only one hardware wallet). butTaking the perspective of seeds, two seeds are compromised.

My first question is whether an attacker can discover two seeds and steal funds, or three seeds Must do To replicate the wallet and steal the funds? (I assume that an attacker can access two seeds to reproduce the private key and (It’s not possible to use a multi-sig wallet set up on my personal computer). Because collecting multi-sig wallets with Electrum requires three seeds (or co-signers of one seed and two public keys), but I really want to reaffirm with the community. Bitcoin cannot find two seeds and move. Note that in this setup, you need mobile Bitcoin to co-sign with hardware wallet 3, in this case either hardware wallet 1 or 2, so you need cold cold storage effectively.

Another option is to create a Hidden wallet Comes with a passphrase using one wallet. In that case, two copies of the seed and two copies of the passphrase can be stored in four geographically different locations. If seeds are found, you cannot access the hidden wallet, and if you access the passphrase, you cannot replicate the hidden wallet either. The only vulnerability in the latter case is when a hardware device is stolen and used to transport money (though physically tampering or using it may limit use of device pins).

My second question is whether the first option gives a significantly higher entropy for protection. Note that in storage costs, the cost is the same as having to use four locations in both cases.
