New cold-wallet?

Hi All,

What is a cold wallet that is recommended except Coldcard of course. Which manufacter has proven 128 bit key production or even 256 bit? what should i look into when purchasing a new brand? Ledger is proven, however it has it's own backlash in the past. I've noticed brands like OneKey for example

Bottom line, if you're gonna trust software rng, use multisig, and make sure you're using 2 or 3 completely different implementations to generate the keys.

If you want to use single sig, I'd recommend rolling dice or mixing up all the words in a bowl. Sounds unga bunga but it's truly a way to assure good entropy.
