This isn't 2011. Not sure if you've been here recently but Bitcoin is fairly well respected among HNers today.
Yes, as a currency for money laundering and buying drugs online - highly respected.
It's also known for launching ETFs, buying subway sandwhiches, buying real estate, storing wealth, and feeding the homeless among other things.
Bitcoin is respected among some HNers. There are still a lot of people who question its value, its long-term prospects, who call the current price spike a bubble, who call it a toy/gimmick/scam/etc., and so forth.
Unproductive comments have never been accepted on HN either way.
