Keep in mind the time of this original post was right after the huge crash in 2011 where everyone was saying Bitcoin was done for. It echoes the sentiment of the time.
The only people who thought bitcoin was done for, were those only in it for the profit and not informed enough to understand bitcoin's significance.
The price of bitcoins does not matter for bitcoin the protocol.
I remember those "dark months" after the bubble, where nearly everyone on the forum was spouting the most negative crap. I think people who didn't understand this thing lost a lot of money, and wanted to make the community feel bad about it.
Those of us who stuck through it were the ones who took their profit. From weak hands to strong. This capital is too important to be in the hands of those who don't understand the potential of this system.
I initially bought in at $14 after the high (i didn't understand the idea of correction at that point, but from the start I understood the fundamental idea of Bitcoin and stayed with it) - I sold out at about $7 due to cowardice, but I still believed and waited for some positive signs and bought back in more substantially at around $3.
I suspect every newbie goes through this at the price point they first buy into - belief, hope, despair, hope, belief.
Bitcoin is a baptism of fire.
