I apologize if this has been brought up before. If it has, please feel free to merely direct me to the applicable thread. As an investor, one of the hurdles I am having a hard time getting over is the following: What happens to the market for bitcoins when/if a vastly superior design is found? What is the probability of an unquestionably superior design being found?
There are things vastly superior to gold bullion or even ebay, but the two are still going stronger than ever. The thing that will make bitcoin valuable is not a superior design but how widely it is accepted as a currency or commodity.
