When I see this am so happy. We can add that from all the world it is the same charge and the time of arrival through out the world.

This reminds me of someone who has recived money from a brother in Italy. He has gone to the bank to remove it. Now while his brother was sending it to Ghana he paid something for transaction fee. As soon as you withdraw you area asked to show pay a transaction fee. Ok the blockchain this is definitely not necessary.
