That's right. What I might recommend is to have your seed splitted in 2/3 way, which means you can read your seed while having any 2 out of 3 copies. Yet with only one of copies you cannot get the seed as it will require you to crack 8/24 of seed which still will take at best months if not few years. This requires having 3 safe locations, possibly different physical addresses. You should have them in a place where you can check each few months if it was untouched, for total peace of mind. ^{It's easy to do, but If you need details I can give you some instructions if you PM me. I'll probably make a tutorial at our site in the future too.}

Sounds like you are talking about Shamir's Secret Sharing. The problem with SSS is its single point of failure. The splitting part is done on a single device and the reconstruction of the shares is also done on one device. That's the single point of failure. Jameson Lopp talks about it in detail here. A standard 2/3 multisig setup sounds like a better idea.

I'd also advocate for Multisig instead of SSS. It was discussed on this forum at length, a whole bunch of times and if memory serves correct, Multisig always came out on top.

Even Gregory Maxwell himself seems to agree with this:

[...]
It is my view that In general, secret sharing is largely snake oil in practice because you must have a computer to split and join keys and if that computer is compromised your security is gone. If you really had a compromise immune computer, just leave your key there and avoid the pointless ritual.

Bitcoin has multisignature which allows split keys without any single point of failure. Anyone considering secret sharing should first have a darn good reason they aren't using multisig.

I didn't mean Shamir's Secret Sharing, it's probably too complicated for most of ppl including myself. Not a biggest fan of multisig, but it might be nice if you have a big holdings. I meant just very simple idea that you just split your seed into thirds. Then each copy has 2/3 of the full seed on itself. You just do it manually, low or no tech approach. For example 1st copy has words 1-16th, 2nd has 9-24th and 3rd has 1-8th + 17-24th. I think that it's simple and it works, it might be good enough for most long term hodlers.

That's actually even worse! If you lose 1 part, the whole thing's gone. Never do that!
