I don't think that you understand how decentralized cryptocurrency works.  As soon as you release it, you no longer have control over it. You can't just develop it unless you maintain over a 51% stake so you can fork it at will.  As soon as it is released it is out of your hands.  That's why bounties exist for development.  Anyone with a premine is a fraud as they can't guarantee any development besides superficial things like marketing.

If you want a centralized coin that is controlled by the company that makes it and they distribute the coins how they see fit, then that is a whole separate thing.  It is called a centralized digital currency.
