Are there other wallets where bitcoins are most secure?
I want your opinion.
The most secure wallet for bitcoin-stash -storage is a multisig wallet with at least co-signers represented by HW from independent makers. In my view, the best available HW you can find are Passport 2 and ColsCard MK4 (or coming ColsCard Q1). I would advocate reading
this tutorial which sheds the light on creation of Passport 2 - Sparrow - multisig wallet. It can be easily adopted to any arrangement of cosigners.
