Edit: yup, its an instamined coin. 20% of all the coins are going to be mined in the 1st month, and more than 50% until the end of summer. http://coinia.net/groestlcoin/reward.html
Thanks for pointing out. I just spent half a day mining this shitcoin.
Nothing wrong about mining 50% of the coin within half a year, it's fair and suits investors, if you don't mine today you will regret tomorrow, it's the way to coin is designed, just check PTS (to be fully mined I believe in 1 year and 5% reduction every week) or MMC (fully mined in 2 years, 5% reduction every week). This is not instamined, the launch was fair with DGW from the beginning.
