2000 BTC is roughly equivalent to around 134 million bucks which is why I would prefer the best option available even if meant spending a million bucks to successfully store the remaining 133 million bucks.
If nuclear sheltered vaults are the best option, I would obviously store all my BTC though I would research them thoroughly beforehand.
seems overkill if there is a huge storage cost. I think at this time for the storage of bitcoin assets it does not have to have a high security system, but the most important thing is that our storage is in a safe place. it's better than wasting a lot of money
