Just found out that there is mining pool still on old chain before hardfork:  https://yiimp.coin-mining.eu/ of NENG on this same old chain as Dave reported.  Whoever owns this mining pool,  please update to our latest wallet post v1.3.x hardfork.

Also, all new members please do not mine on this pool until the wallet is upgraded to post-hardforked wallet: coin-mining.eu .  At this moment, all coins mined there are on dead chain and will be orphaned and disappeared once the wallet file is placed in new version post-v1.3.0 hard fork.

Base diff reset has been unpredictable on timing recently.  It used to be once every 1 week.  Now sometimes once per two weeks,
sometimes twice reset within one week.  In the end it is big ASIC miners and big GPU solo miners who control the cycle timing because reset is likely to happen couple of days after they left.

NENG base diff has reset to low level, boom for solo GPU or. Solo small ASIC miners.

There are still people mining on the old chain. Please be sure you are using the new client.
@honglu69 you should probably change the code to something that shows that you are on the newer client. Having the same .8.7.5 is probably causing some of the issue.
I missed updating one of my CPU mining nodes but it still saw new blocks as of this post.

Stay Safe.

Dave,

Very good point.   I am surprised that there are still client on old chain.  

I will look into it to change the version tag number.  

A new issue is created at:  https://github.com/ShorelineCrypto/NewEnglandCoin/issues/9

I'm currently mining with 2 Futurebit Moonlander 2s and Im pulling in about 20 mil coins a day. Good rewards right now and easy to mine.

Congratulations. You are on the high end of rewards on reset day.

A research on big ASIC miners yield on the reset low base diff:
https://zpool.ga/site/block?id=1533

346 mh/s  hash rate, likely an ASIC pod or better.  In terms of hash rate, this is likely a dominant miner now.

From  Height 1374201 to Height 1374987,  total of  787 blocks,  this big  ASIC miner obtained 161 Confirmed blocks or 20.45% of total rewards.    It has lots of orphaned blocks (67 Orphan blocks), mainly due to randomSpike rejections.

This hashrate is probably more than 90% of total of current network hashrate, but only getting 20% of rewards because of restriction from randomSpike.

So far randomSpike is doing good job to spread out rewards and restrict big ASIC miners during low base diff period.

base difficulty has reset to very low level. Boom for GPU solo miners and small ASIC USB solo miners.

Did difficulty drop again? Just looked in on the one machine I have left mining and I have gotten a ton of blocks in the last couple of hours.
Usually I see a post about it here before I really see tons of blocks coming.

Stay safe.

Not yet, the base difficulty is above 17.  I think probably big ASIC miners left and you have Cheetah_CpuMiner running there.  Cheetah CPU solo miners are dominating pretty much all the rewards now.

Timestamp miner cheating warning was back, but it was obvious that the timestamp manipulating miner was not getting that much of rewards.

Based on below, from 1348466 to 1348871 height for total of 406 blocks, the below timestamp attacking miner got 34 blocks reward, or 8.4% of total rewards over two and half hours.
This is about 4.5 minutes per block reward.  This was not that much.  A USB ASIC solo miner such as futurebit moonlander 2 right now can get better reward than this on solo mining mode.

Scrypt RandomSpike algorithm is doing well so far as designed on this issue.

ASIC big miners are in NENG mining pool mainly. More than 2 Gh/s hash rate are right now.   ASICs are dominating the rewards now.  Base difficult at 8.6

I just noticed that currently the base difficulty is very low, almost close to zero.  This is not good time for big ASIC miners on pool because randomSpike algo on top of scrypt restrict ASIC.
I noticed that there are 40 mH/s hash rate running in FindBlocks mining NENG, only getting 3 blocks in last one hour.  By the way, I am running a USB ASIC stick with  less than 3 mh/s hash rate solo mining NENG, less than 1/10
of the hash rate, but getting one block almost every two minutes now.  

Just be warned here for any new big ASIC miners on NENG if you are not aware of special algo of NENG.  It may not be smart now to mine NENG on big ASIC rig, which cost lots of electricity and noises.

Just noticed there are more than 100 Mh/s running in CMinor's pool too with poor results. Just be warned on this same issue above.
