How much did your biggest crypto mistake cost you?

I'm not talking about buying this week's latest shitcoin and taking a -90% bath, but more so sending funds to the wrong address.

Last week I sent 12 ETH (over $10k) to the wrong ETH address. It was gutting lol. Luckily it's not my whole ETH stack, but it served as reminder to check every single address before you send it. Previously my biggest loss was $50 back in 2019 with Bitcoin.

What has been your biggest address mistype? I can't offer a refund on your misspent funds but I can offer a positive comment…. and if your loss is bigger than mine, it might even make me feel a lot better!
