Calculating a P/E on transaction fees seems silly because frees on a crypto currency aren't related to the amount of value moved they are related to the number of bytes of space your transaction takes which in a simple transaction is most effected by the number of source and destination addresses used in the transaction. A better way to calculate this fake P/E ratio would be to look at the total USD volume of Bitcoin transactions and take 2% of that as the "earnings" logic being that if a coin were a credit card like company their earnings would be 2% of thier transaction volume. Still a bit of a contrived metric but at least related to the economic activity taking place.
