Offline crypto wallet

Where do you keep it, that you think it's secure, is the most important question.

why wouldn't you just put it into blockfi or nexo and collect interest?

I still haven't gotten that email yet..

Trezor is a very popular one as is Ledger Nano. I’d avoid the Ledger because they had some data breaches and I would not trust them now. Coldcard is what I’d get if I had a substantial amount of crypto to store as it’s the most secure of the 3. All 3 are better options than leaving on an exchange.

I’m using my ether wallet with metamask on my browser. Computer is only used for crypto stuff.

In theory I need several wallets - hot wallet to trade, cold storage wallet to store.

The hardware wallets increase security more as well.

and the wallet which collects interest is the most superior of them all

Kraken(trading bags) & Ledger(hodl) are the answers you seek
And a VPN till KYC is mandatory everywhere

They show up to your door with a pipe wrench yet?

operate bunker style in crypto world- different emails for different things; exchanges / forums / cointrackers and send your hardware wallet to untraceable POBox or office is advisable.
Some wiseguy is mapping rich addresses on the mailing list and people's kids will be threatened for the seed words in the future.

No, the Ledger data leak did not leak the bitcoin addresses or any coin amount. It only leaked the physical mailing address that the Nano Ledger was shipped to (and emails associated). With that said, still not good at all.
