Update on the lost ledger nano story:

Yesterday, my wife actually said to me that i seem to look worried, while in the middle of the lost ledger quest (Not because of the Covid).
I told my story and she said: "Hey, you told me you were hiding it in the basement, because you were worried that you can't remember when we return from the holidays." 
Good girl 
So i went into meditation a couple of times, until i had remembered some kind of dark picture of the place where i put the fucking thing.
And then it clicked. I had put the ledger in an empty packaging of some usb device (bluetooth stick?) where it did fit really tightly.
A few weeks after our vacation i was cleaning our old stuff in the basement, and i almost know now that i had thrown the ledger nano away.
So there's a little chance that i didn't go to the recycling center but threw it in an intermediate container, no need to be too precise here. I plan to look through the (luckily, non-organic) waste later on.

If i can't find it there, it's lost for sure. If somebody finds it, that somebody has three attempts to guess the pin code, then it will auto-reset on failure.

Seems safe to restore the wallet(s) to the spare ledger i happen to own.
But i failed to decide if i would create a new key and transfer my Bitcoin from a recovered software-wallet. I am not sure which way is the safer one.

Any suggestions?
