If the data from this poll mean anything, it's that when the $/BTC begins to crash, there will be many optimists to buy it all back.
At first, probably yes. However, sentiment can turn from bullish to bearish pretty fast from what I've seen
Nobody was actually bearish during the crash, as in, "This will end the rally." People sold to buy back lower, and they clearly did, because we're at $70 now.
There were others that simply got liquidated.
