Ah! To clarify, I don't let my investments sit on exchanges. I keep them in wallets off of the exchanges. Thanks for the concern though! If I was leaving my investments on exchanges, that would definitely be concerning. Even the most secure and reputable exchanges are targets and can be vulnerable to hacks. Some people never think that it will ever happen to them until it actually does.

I am looking forward to getting a ledger though. Once I get one, I might invest in and place it in a nifty little fire safe. Might be a little overkill.. but actually maybe not? What if that 21 word passphrase were to get burned up too in the case of a fire? haha :)
