NewEnglandcoin (NENG) is dynamic difficulty algo on top of scrypt. The NENG bitcointalk ANN:
https://bitcointalk.org/index.php?topic=5027091.0The recent v1.2.1 release of NENG last week essentially enabled GPU mining on this coin. Historically this coin was mainly mined by ASIC miners or CPU miners. NENG was never friendly to GPU miners until the recent v1.2.x release. v1.2.x core release essentially imposed a spike difficulty within 3 seconds of last block. The spike difficulty currently sit at 244k, which means that instant mining is stopped on NENG. It also means that NENG becomes quite ASIC-restricted recently.
At this moment, my estimate is that GPU miners are dominant force on NENG mining, followed by ASIC or CPU miners. Just a tip, do not join a mining pool for GPU rigs. Just do a solo mining setup and the rewards will be quite big at current low base diff (0.00192499).

NENG CPU mining info: Historically after v1.1.1 release, ASIC miners mined probably 60% to 80% of blocks, the remain blocks were mined mainly by CPU miners using its own
Cheetah_Cpu miner software. There is already a CPU mining thread on this (
