I am not understanding the whole they are gone thing.. arnt they saved on a server somewhere never to be touched.. therefore the value of the coin will always be saved?.. I is confused.
Gone in a way that is similar to a gold bar dropped into the Mariana Trench is considered "gone". It still exists, but is is no longer accessible. Of course, with a gold bar in the Mariana Trench, there might be a chance of retrieving it with current technology. With lost private keys, there is no currently known technology that would allow you to retrieve it.
