21gh is owned by 8 users on one pool. this coin is worthless to anyone mining with with less than 100mh. no this is not normal. they will dump all coin on market.
looks more and more like secret x11 asics
groestl is the only anti-asic algorithm. x11 and all other xver algos are compromised. x15 is botnet dream algorithm.. waste of time for real miners and investors when others can mine for free of charge.. not even using electricity.
