At what amount is it worth buying a cold wallet? How much BTC should I have before getting one?

Hi everyone,

I’m currently keeping my crypto on an exchange, but I know that "not your keys, not your coins." I want to move my funds to self-custody for better security, but cold wallets can be quite expensive.

I'm wondering at what portfolio size it actually makes sense to buy a hardware wallet (like a Ledger or Trezor).

• Is there a specific dollar amount or BTC threshold where it becomes a must?
• What percentage of your total portfolio value do you think justifies the cost of the device?

I would love to hear your thoughts and experiences on when you decided to make the switch. Thanks in advance!
