Grandcoin pools are scamming?

[momchilandonov]

I've mined on all GND (grandcoin) pools I could find...
They are
http://gdc.nordicminers.eu/index.php
http://grand.cryptcoins.net/accountdetails
https://www.miningpool.co/dashboard/

and I think 1 or 2 more which closed for some reason and I don't recall their sites.
I am 99% something is not right with either the coin or the pools themselves.
I am rewarded around 10 times lower the amount I really should.
I have a single HD5870 with 400 khash/s mining nonstop with no HW errors using cgminer and low amount of rejects.
When the difficulty was lower around 1-1.6 I had to get around 8000-10000 coins per 24 hours which equals to around 333-416 coins per hour.
YET I only get around ~30 and at best around 60 coins per hour.
I don't have ANY problems mining Worldcoin (WDC) just for comparison.

Same for me ........... something doesn't add up with either the coin or the pools.

Receiving approx. 1/10 of the estimated on a 5 Mh/s setup on all the pools listed.

Same here, P2pool is no better.

GDC.DEDICATEDPOOL.COM just opened, i'm curious if it is any better.

I started solo mining a couple of hours ago.   We'll see how that works.   Let me know if you find a good pool ...

I am currently testing gdc.dedicatedpool.com and here is what they say:
UPDATE: It has been deemed that there is a serious bug with the grandcoin wallet daemon, that rejects solved blocks. This affects all pools - it is why shares to solve are much higher than estimated.

BTW the difficulty even there is varrying.
Will post results soon here.

Well for 20 minutes mining in http://gdc.dedicatedpool.com/ I received 8.66 GDC but with calculations using coinwarz calculator I am supposed to get around 56 GDC per hour at 400 khash/s so the bug is still happening and the pools won't benefit that much - otherwise nobody would use them for more than 2-3 days and will complain about it. I purchased around 1000 GDC at 0.00000500 BTC each and I hope they get back to around 0.00000900 or some per BTC price .
Elephant coin is also bugged or the pool http://elp.botpool.net/ is cheating because according to it I should be getting around 560 ELP per 24 hours yet for 20 minutes I only get 2 ELP which is around 24x6 = 144 ELP per 24 hours. 144/560 = 0.25 which is only 25 percents reward instead of 98% after tax for the pool. I can accept 5-10% but stealing 73%

Have the same problem. Check this: https://bitcointalk.org/index.php?topic=255629.220

There is a bug in the software. Hopefully they fix it FAST.

Grandcoin? Never heard of them  I'm currently mining DOGe coins from last week and got a fantastic ROI 

[oaks05]

stay away from grandcoin for the time being, there difficulty level is off, you wont receive anywhere near what it says on the mining calculators.

I just got 1000 coins after solo mining for under an hour.  nice, huh?
