I see links to two very unscientific, self-selecting polls with small sample sizes. Basically useless.
The short term and long term expected value of bitcoins is currently 75 USD per BTC. That is what the market is telling us. Some people may be overexcited and expect to make 1000% returns, but if the overall consensus was that the price would be over $1000 in a couple years, then the price would quickly correct to over $1000 now.
