please remember that the current prices for StarPro are dependent upon the amount produced in the game, so if you don't spend your StarPro but are selling it, you make it for free (bigger prices for other goodies) but if you only get enough to use in the game then look at the benefits versus the detriments of a cost analysis. you make StarPro from the Starbits you generate in the game and you use the StarPro to enhance your experience in the game buy performing missions faster, or receiving cards in the game that expand your ability to earn more Starbits.
So by not using StarPro in the game you are deciding to handicap you own enjoyment and limit the rewards that you can gain.
The current prices for StarPro are the result of a hostile takeover by an investor named wagginston.
I know it, everyone else knows it, and you (currently 71st in the player rankings) should know it too.
I have made my position clear and will not change it.
