There is now an updated version of cgminer based on 3.7.2 (kalroth cgminer 3.7.3) with support for MaxCoin’s keccak (SHA-3) algorithm that is more stable and optimized than the previously available cgminer 3.6.6 with keccak support. So if you are still using the old version 3.6.6 of cgminer with keccak support, then you better update to the new cgminer 3.7.3 kalroth release for mining MaxCoins (MAX). You can also build the miner yourself from source if you wish.

The Litecoin Difficulty has dropped again, this time from 3508 down to 2674 (-23.76%), so the LTC mining profitability is yet again higher than on the previous difficulty. The reason of course are the many users mining for DOGE, MaxCoin, MetisCoin, VertCoin and other alternative crypto coins instead of directly mining LTC. At the moment DOGE profitability is just about 15% higher than directly mining for LTC, so you can very well expect that the next difficulty adjustment for Litecoin will go up and then down again and then up as the tendency has shown lately. This makes the use of pools such as LTC Rabbit an interesting alternative than directly going back to mining LTC as you are still getting payed directly in Litecoin + some altcoin bonus as an extra.


If you have Bitmain AntMiner U1 USB sticks for Bitcoin mining you would need to use a special version of cgminer that is compiled to support these BTC ASIC devices. Below you will find cgminer 3.8.5 for windows that is compiled with AntMiner U1 support along with BAT files to run the USB ASIC at “stock” frequency for 1.6 GH/s, along with settings for running the device at 1.8 GH/s, 2.0 GH/s and 2.2 GH/s. Just make sure that you overclock the AntMiner U1 for higher hashrate to ensure that the device is properly cooled – you need to provide additional fan blowing on the device to cool it down when it is overclocked. Do not, and we really mean that you should not overclock the AntMiner U1 without additional cooling or there is risk of damaging the device!
