This subtlety matters though. Some people claim bitcoin is doomed if the exchange rate drops any more. In reality, though, all that matters is that the price stabilises somewhere. Whether that's at 0.01 USD or $1000 USD makes little difference.
Some people, who are used to dealing in multiple currencies, don't even think that matters. While $/ might not move more than 20% over a few months, you still have to hedge for currency volatility just as with Bitcoin.
