What hardware wallet you recommend to store ( for a long time ) my bitcoins?
and does offline storing more recommend?
thx
I'll leave two options of which I've used before.

If you're going to store large amounts of btc and you're fairly new to bitcoin, then yes. Storing offline is recommended, if you're new or not.
