If you are mining Scrypt crypto currencies such as Litecoin or maybe DOGE, then you are most likely using cgminer as a mining software or something that relies on cgminer as a backend. The author of cgminer (Con Kolivas) however seems to have decided to continue support of cgminer only for ASIC mining for SHA-256 cryptos such as Bitcoin and version 3.7.2 is the last one for cgminer to support GPU mining for scrypt crypto coins. Furthermore the windows version of the last cgminer to support GPU mining has been removed from the official download location, you can however download cgminer 3.7.2 with GPU support for windows here.

More importantly, there are already some alternatives that are based around the original source code of cgminer 3.7.2, but add extra features and offer improvements that are not found in the original software. One such version based on cgminer 3.7.2 is Martin “Kalroth” Danielsen’s cgminer 3.7.2 that he calls cgminer 3.7.3 in order for the users to be able to differentiate between the original and his version. In cgminer 3.7.2 kalroth (cgminer 3.7.3) he has made changes to the visual interface to make it more user friendly and functionality that can help you squeeze a bit more performance out of your GPU mining hardware. Some of the notable differences include support for multiple pool load balancing, implementation for idle state for GPUs when there’s no work, two additional modes for controlling intensity – xintensity and rawintensity for additional performance, faster failover pool switching back delay and interface improvements such as uptime status or percentage of rejected shares and so on. Definitely something to try and see if you like this version of cgminer better than the original 3.7.2.

The 6th day of our Butterbot automated Bitcoin trading bot testing has passed and it is time to see what has happened in the last 24 hours. On the BTC-e exchange we got a new trade, as a result we now have 24.77 USD balance so we are a bit short of the initial 25 USD that we started testing with. We’ve had a bit more in a previous trade, so we were actually making some profit, but at the moment we are at a short loss. Again not very active in trading, and this is what you should expect from this automated trading bot with the recommended or slightly optimized settings, though you might be able to make the bot trade faster with higher risk.


The fourth day of testing Butterbot on the MtGox exchange produced no trades at all and our balance is still 37.37 USD, but the general trend on the exchange was down, so maybe tomorrow we are going to see some trades. Don’t forget that the current market state and the trades at the exchange are very important to how an automated bot may react and execute trades or not. We have one more day left of our trial period for testing the Butterbot automated Bitcoin trading bot, before making the final conclusion if we are going to purchase and continue to use it or not. So far we are not too happy with the results we are getting and we are already looking for other alternatives to try out next, but let us finish with the Butterbot testing first.

Vertcoin (VTC) strengthens the distributed nature of crypto currencies with its innovative approach. It’s ASIC resistant, Multipool resistant and Rare. Vertcoins algorithm has been designed to resist the development of custom mining hardware, and multipool mining ensuring that transactions are validated by a widely distributed network and avoiding the selling pressure when large mining pools indiscriminately flood the market with freshly mined coins. Vertcoin does not use SHA-256 or the typical Scrypt algorithms, making it another very interesting alternative to BTC and LTC. Vertcoin (VTC) is already generating a lot of hype, so the exchange rate will probably explode since the addition of this crypto currency at Cryptsy.
