Are you selling PTS to pay for the overhead? If not, seems moot to me given they'll be exponentially more valuable if you succeed and not much less valuable if you fail.
Either way, if the project does ANYTHING the value of PTS will go up far beyond where it is now, so why do you need to take a short term approach? You WANT it to be percieved as a good value because otherwise why would someone want to do it. If you don't believe in the future value of your currency why should anyone else.
