mined 6hours on multipool.us yesterday with hashrate of 2300kh/s only received 1300doges wtf?
Try
https://doge.netcodepool.org for 24 hours and see the difference. We moved onto Amazon servers and added more nodes, now our block luck is very proftiable.
just fyi, netcodepool is an admin on dogecoin's official subreddit /r/dogecoin which no other pool is, that sums it out. Yes I have another question for your pool also

have been mining alot on your pool in the past (mining on it right now)
did look into transaction history and I have noticed something weird (see screenshot)

What does that mean?
