idk the whole point of hardware wallets is that they are supposed to be a simpler stack. But if you're using a closed source hardware wallet...

An old laptop with the wifi card taken out is more transparent and auditable. It just runs the ordinary open source code

But I just keep all my funds in a hot wallet, no multisig. And if I get hacked I lose it all. I think the answer is just have good security and dont get hacked. The risk of losing cryptocurrency will encourage security advances across the whole ecosystem. I think I will set up multisig eventually
