Let me explain something to you, there are 2 points:
1. Why would you assume that it was 1 btc for 1 dollar? Everyone knows that absolute majority of world currencies are not equal to exactly 1 dollar.
So assuming otherwise is pretty stupid.
2. Everyone who spends even half the time on GFY than you have seen NUMEROUS threads about "bitcoin hit X amount" etc threads. It was impossible for anyone to miss that. Seriously impossible unless you have retarded attention span syndrome or something.
While some very rare people might fall in either 1 of the above 2 categories (assuming that most currencies equals to 1 dollar or somehow managing to not notice a single of BTC threads over the YEARS), falling into both categories all together takes special kind of retardation.
Seriously:
Who here assumes that some/any currency they hear about equals to 1 dollar? Pretty sure nobody as they know that(almost) all currencies have different value.
Answer: Nobody (most likely).
Who here (out of those who spend decent amount of time here) never noticed BTC thread or any BTC value related post etc? It was impossible to miss.
Answer: Nobody (most likely).
And now imagine one person who managed to be BOTH things
