ahhh. another newbie posting in bitcoin discussion when you should be reading about what bitcoin is. please just go back the beginngers section and read more before you come up with your brilliant plant about bitcoin. there are people who have been here from the beginning and know way more than you. bitcoin doesnt need shortcomings fixed, it CANNOT BE EVERYTHING AT THE SAME TIME. it is bitcoin and it will stay what it is.
