How do you do that without bringing cold wallets online regularly?

  A wallet doesn't need to be online for to be identifiable and its balance verifiable through the blockchain.

    It needs to come online to prove that you haven't lost the keys.

      Or you could use the key to digitally sign a message (that contains something like a newspaper headline or football scoreline) periodically? Besides, I don't think losing the keys is the root cause of many exchanges' solvency issues.
