What hardware wallet you recommend to store ( for a long time ) my bitcoins?
and does offline storing more recommend?
thx
Main ones are definitely trezor or ledger.
I'd recommend trezor for long term because it is obviously looks a lot cooler than ledger nano, which just looks like a USB and I think it is also waterproof, pressure proof and everything else proof to some degree

You can also store your wallet recovery seed i think, using cryptosteel which is amazing.
Completely offline storage, no need to worry about hacks at all.
