|QUESTION| What was the biggest amount you've lost on a wrong transaction

Wrong wallet address, unsupported BLOCKCHAIN, forgetting your 12-digit code?

Anything could count, what was the biggest amount of coins you've ever lost?

The biggest money I have lost was only 20 dollar, yea it wasn't that much but still I remember it really hurt to lose such money only because I've sent it by the wrong BLOCKCHAIN...

Other than that, in total I have probably lost more than 50 dollar but since I only send 1 dollar to try a wallet address and see if it really gets the money first, I didn't lose that much.
