Regardless of what the current USD to BTC exchange rate is, the fact is that people can buy goods and services in BTC for prices that reflect their value is USD. This is what give BTC its value.
The OP claimed there were analysts who claimed that bitcoin should have the value of zero, or at least less than the $7 for which you can buy it now.
I have never seen anybody with any half-rational arguments who claimed that it should be valued at $1 or $0.01 or whatever, and if those predictions exist it would be very interesting to see them.
