Many coins have premined coins for many reasons (look at all the majors). I'm sure their use will be explained in the road map and white paper. While a giveaway or a burn would be nice, right now the focus needs to be on having the coin listed on am exchange. Some exchanges request some of the coin first up, hence the need for some premine lying around I guess. Let's see how this goes.
Let's hope so, but a lot of users will have the fear that Dev's would dump those coins at a first opportunity, that's why some coins will lock out a big part of the premine for some time, another good way to get rewarded for the work is to allocate some % of each mined block to Dev's.
Ex: I rather those 1.200.00 coins being given to DEV's overtime as a % of each mined block, than as a premine.
