There was a very small premine before hand. This was done just to make sure everything was working properly. Since this is the first coin we had ever made. All coins that were premined will eventually be given out as tips to others who would like some gabens. For more information you can see the github page
https://github.com/gabens/gabencoin or you can ask me and I will try to answer them to the best of my knowldege. Although it is getting a bit late for me and I will go to bed soon, so i will answer them in the morning.
Also this coin was not made through coingen.io. Someone else apparently was trying to make the same coin. This was done by me without anyhelp from coingen.io. That is something seperate, did not know about that until just now.
