This coins difficulty is going up higher than the ETH difficulty even
Those who haven't received their ASIC yet must be really feeling it every 30 mins that the difficulty adjusts higher and higher.
It adjusts 0.40% every block. So it will take a while to adjust up to a fair difficulty.
Fun fact: Out of the 15,000+ A3's that Bitmain sold last week, only ~1,700 are currently mining.
