If the price went to $100, why would you buy?

While prices are set by traders, it does need a reason and if the price drops that far, then Bitcoin must be on deaths door!

The reality for me is once my coins drop to a value equal to what I spent on them in fiat, I will worry - although the reality is, I have already taken that money out and spent it on stuff!

If bitcoin dropped to $0, I wouldn't have actually lost money - but I doubt that will happen in 2014! ;-)
