how to swap newe to neng for local wallet

For local wallet,  NEWE wallet file and NENG wallet files are compatible.  Also data files are identical too.  Just renamed backed up NEWE wallet file drop "wallet.dat" into wallet data folder.

Use the guide in wallet "upgrade_newenglandcoin_wallet.txt" when you download windows/macOS/linux/android new v1.5.x wallet and do the upgrade.  
windows version:

Hi, I'm trying to mine on android, but I couldn't execute this command (d. ./nengcoind (create wallet folder & files)), when I type ./nengcoind the message "No such file or directory" appears
Can someone help me?

Can you come over to discord "support" board for help?
Most likely there is something wrong in your android procedure, for example, wrong platform (arm64 vs armhf),  or you are running on wrong dictory folder path.  Also post some screen shot of your phone UserLand app commands for that.

There is one big CPU Miner timestamp Attack


There is one big CPU Miner timestamp Attack
It appears that there is one big CPU miners doing timestamp manipulation and trying hard to monopolize all the NENG mining rewards. It appears it trying to stamp 2 minutes ahead and then 2 minutes behind and getting a lot of block rewards, driving out other CPU or ASIC miners.

Timestamp attack happened on GPU or ASIC miners before. CPU miners attack on timestamp is new on NENG. Cheetah_Cpuminer software will do a big upgrade tonight to address this unfair mining competition issue.

See the screen shot:

base diff shallow reset, boom for USB ASIC solo miners
base diff just did a shallow reset to 0.044 earlier today. This is too high diff for an average GPU solo miners. But this is boom for USB ASIC on solo mining modes such as Futurebit Moonlander2 USB on two rotating nodes.

NENG base diff just reset, boom for GPU/USB ASIC miners
NENG base difficulty just reset to close to zero. Another boom for GPU/USB ASIC solo miners

All the mining pools are on old NewEnglandcoin chain

Just checked and found all the mining pools are on old newenglandcoin chain. They are no longer valid on Nengcoin, please do not mine at pools until they upgrade the wallet to NENGcoin v1.5.x version

Base Diff reset to 0.000244, boom for GPU/USB ASIC solo miners
Possibly because of hard fork today, base difficulty of Nengcoin just reset to almost zero at 0.000244 diff. Another boom for GPU/USB ASIC on solo mining mode.

Attached screen shot below just shows my ccminer on GPU solo mining setup on GTX 1050 card, several blocks in a few minutes of mining Nengcoin (NENG):

Nengcoin block explorer issue
Nengcoin explorer is slow to catch up because database fresh updated from start re-syncing. However, the node behind the block explorer site ( http://nengexplorer.mooo.com:3001/ ) is already updated to latest block. To know the last block , you can check the right bottom corner of block explorer page as shown in below screen shot:

https://www.reddit.com/r/nengcoin/comments/kmuzzx/nengcoin_block_explorer_issue/

As shown above, the explorer page on chrome browser says the total block count is 2,356,011 with 30 full nodes connections.

Also the block explorer difficulty display on the top is also latest to newest Nengcoin block.

Nengcoin pool for ASICs
One pool Cminors is on new Nengcoin (NENG) blockchain even though the pool name is still on NewEnglandcoin.   Pool info on bitcointalk Ann page is updated on this.

Nengcoin pool for ASICs

Cminors is back on old NewEnglandcoin invalid chain again. There are no mining pool on Nengcoin now.

ASIC Pool on Nengcoin


Cminor has fixed pool issue,  Now Cminor is on correct nengcoin chain even though the name is still Newenglandcoin

Google chart is also provided in above URL.

Please note the sharp sell off in Dec 2020 was due to last minutes big sell off at very low price because of NewEnglandcoin (NEWE) delisting. Instead of withdrawing all NEWE, some traders decided to sell off NEWE at low price instead while Nengcoin (NENG) was trading at much higher price.

Note for the records of 2020 whole year price performance on NENG:
12/31/2019: 0.0000119 NENG/DOGE
12/31/2019: Dogecoin price on USD: 0.0020257 USD

12/31/2020: 0.0000508 NENG/DOGE
12/31/2020: Dogecoin price on USD: 0.0047

NENG rose 327% against Dogecoin in 2020 whole year. Dogecoin itself rose 132% in 2020 on USD unit. Under USD unit, NENG rose roughly 10x in 2020 whole year on USD term.
