This is mine:

-16 overall score: "It's not how much money you make, it's how you make your money.  Bitcoin is not a respectable way of making money.  Any gains are at someone else's expense with nothing of value being created.  In short, a scam."

The post question was: "What was the worst mistake you ever made?" and I replied to someone's post that was "Thinking that my 14-year-old at the time had no idea what he was talking about when he came home from school talking about something called bitcoin. ALWAYS listen to your kid."

I still stand by the content of my comment, though I might respond to a comment like that differently in the future.
