Nunchuck Wallet vs sparrow which is more secure long term
Both are software wallet, but both offers cold storage if I'm not mistaken.
As multiple users have mentioned in your previous post, if you want to keep things as simple and as secure as possible, then going with a singlesig hardware wallet is the way to go here.
And if you have different questions about different wallets, it's probably best to keep one topic and ask everything, instead of opening multiple ones.
