And when that you think that it will happen that a universal crypto currency but not Bitcoin? For now, i see no one can supersede Satoshi's Bitcoin but if Goldman Sachs will create another Altcoin and they will pump it hard just to replace Bitcoin then maybe many years from now that it will become possible i guess.
They can create whatever they want and they can hype it and pump it as much as they want unless they create something better than bitcoin it wont make a difference and they wont do it because they know that bitcoin is based on solid economic principles, fiat currency always goes back to zero, governments are too easily tempted to think that this time is going to be different and they can somehow deceive the people forever and violate basic economic principles.
Satoshi did a very good job at programing something like bitcoin but one of the key components was to make it scarce and with a hard limit of how many coins there can be, something that fiat does not have and it will be the main reason of its demise.
