That is truly awful news.
Why? What is the proportianality of exchange rates to transaction rates?
Exchange rate is approx. $30 per coin currently at current number of transactions per second. What value of exchange rate will it take to drive transaction rate up to 4 per second?

The BTCt fiat exchange rates have no direct influence on the transaction rate. Only the size of the economy has a real influence on the transaction rate, but severe limitations on the transaction rate might be a limitation on the size of the economy.
