yes that is easy but as long as we don't solve the time confirmation for every transaction then we are having difficulties to use bitcoin as our daily transaction. people don't want to wait too long to see their transactions get confirmed and they only want to do with fast transaction with small fee. many people doesn't think that for making transaction, if we use small fee then our transaction will getting slower to confirm in the network. but if the the transaction can go fast then i think people will be happy and they will use bitcoin as their daily transaction.
