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.  Anyone with a premine is a fraud as they can't guarantee any development besides superficial things like marketing and wallets, which anyone can make and people can have bounties.  What is much more likely for a premine is they just want to pump and dump the coin and make tons of money.  No premine shows that the person is doing it for the people.

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.
