Large? I get the lowest PreMine, you van get upto 70% And i only get 1%. Its for the Owner or creator have some coins, if the have a good price, he will can sell at a good price
Large in terms of it seems you haven't invested much time into developing this coin beyond cloning bitcoin and changing few (very few) parameters in the code. Additionally the mining rewards are small, and spaced out by 3min each meaning it will take ~9.68 YEARS for their to be as many coins on the market via mining as what you have allocated for yourself in the premine.
My math:
84,848,485 premine / 50 coins per block = 1,696,969.7 blocks to achieve premine supply via mining
(1,696,970 blocks to achieve premine * 3min per block) / 60min per hr / 24 hrs per day / 365 days per year = 9.685 years
Although dev seems to be good-hearted, I don't think this is going anywhere

I think there would be more support from the community if the premine weren't so gratuitous, or if there was some clear plan to use the premine to better grow the value of this project.
