A bear doesn't talk big bear words on the forums if he hasn't already sold.
A lot of bear talk lately => a lot of people are short => ...
You're right, a lot of bears writes about BTC for $ 30.
Who found downtrend as the first, sold it for $ 130 - 150
That's why I always say change ahead of us, but I'm not sure whether up or down.
Definitely I'm not saying that Bitcoin will definitely a 30 and that left everyone.
Demand at 80-50 is still huge ... A lot of Bitcoin is in "strong hands" that will not sell it. It's maybe different than in 2011.
Edit:
Each bear needs someone to sell below than himself, and each bull needs someone who buys higher than he, otherwise the trend reverses 
I will admit I was extremely lucky, I sold a bunch of Casascius Coins at 1.65 x
BTC current market value at $131.80. It was a cash transaction and by the time I got home to deposit funds and move them back to the exchange the price was dropping and fast. I held and have only bought what I needed for projects. Well that and played a few bounces, but like I said I got lucky on that sale.
