This weeks did not start well for the worldwide financial markets, and things were especially not good in USA and China as a result the exchange rates of Bitcoin and Litecoin as well as other crypto currencies are also down. The crypto currency price volatility is not something new, but the exchange rates dropping at this particular moment, especially for Litecoin, are not that good. Today LTC is expected to have its first block reward halving and the price going down to as low as $2.5 USD means that the mining profitability after the halving will be awfully low if any at all. Though later today we are probably going to see some recovery for both Bitcoin and Litecoin that will also most likely rise the fiat exchange rates for other alternative crypto currencies as well.

According to a Bitcoin Revolution UK report and back on to mining LTC, we had high hopes for SFARDS to have their new generation dual-mining ASIC capable of mining simultaneously SHA-256 and Scrypt-based crypto coins such as Bitcoin and Litecoin. The more interesting parts with the SFARDS SF100 miners is their high hashrate for mining LTC only with very low power consumption, roughly 1/3 of the closest competitor in the form of Innosilicon and their A2 Terminator chips. Unfortunately SFARDS is late, they are apparently going to miss the opportunity to release the hardware before the block reward halving, so their pricing will either have to go even lower in order to get user interest if/when they have wider availability. In fact some people have apparently received first batch units from SFARDS earlier this month, very limited early availability, and the feedback was not only positive. It seems that aside from the high initial price of the miners, there is more to be desired from the build quality and in terms of reliability as well. Meanwhile it seems that Innosilicon is selling well their A2 miners as they are currently the best you can get on the market and with good price policy and availability people that want to mine for Scrypt coins such as LTC have no other choice for ASIC miners.

We are going to see how things will work on for Litecoin, but meanwhile it is already experiencing a strong competition by Ethereum (ETH) in terms of market capitalization. Ethereum has been in development for quite a while, but mining has been officially launched at the end of last month along with the network starting to support transactions a few days later. The current high market capitalization of Ethereum is due to the availability of 72 million coins prior to the mining even starting, 60 million of which were sold to early investors and another 12 million to be distributed to early supporters. AS for the mining part, we have not even reached 1 million coins mined by users as we are getting close to the first month of mining. The expected rate of mining for Ethereum is about 30000 ETH a day or less than a million a month, but this does not mean that there are actually very few coins available. At the moment the daily trading volume of Ethereum is between half a million and a million coins, lately a bit lower because of the general drop in price. On the other hand Augur (upcoming application using the Ethereum network) is currently running their crowdsale and have already collected over 1 million Ether coins from users and close to 10000 BTC. So we are going to be keeping a close eye on the Ethereum development as well.

Blockchain, along with other big names in the Bitcoin industry have just released a public letter in support the implementation of BIP101 and larger Bitcoin blocks. Other companies that have signed the document include BitPay, Circle, Kncminer, Bitnet, Xapo and Bitgo and other companies are encouraged to join. Below is the document quoted and you can also find a link to the contents and signatures of the presidents and CEOs of the companies that have signed it:

Our community stands at a crossroads. The debate about which path to take has, by and large, been a healthy one, and we have not interposed our own positions or interfered in the discourse. Until today, our involvement has consisted of listening, researching and testing. We believe that work is complete, and it is time to communicate our view in a clear and transparent manner.

After lengthy conversations with core developers, miners, our own technical teams, and other industry participants, we believe it is imperative that we plan for success by raising the maximum block size.

We support the implementation of BIP101. We have found Gavin’s arguments on both the need for larger blocks and the feasibility of their implementation – while safeguarding Bitcoin’s decentralization – to be convincing. BIP101 and 8MB blocks are already supported by a majority of the miners and we feel it is time for the industry to unite behind this proposal.

Our companies will be ready for larger blocks by December 2015 and we will run code that supports this.

As our community grows, it is essential – now more than ever that we seek strong consensus to ensure network reliability. We pledge to support BIP101 in our software and systems by December 2015, and we encourage others to join us.

Note that the companies that have signed the letter are pledging that they will be ready for larger blocks by December 2015. Some of the large Bitcoin mining pools have already implemented support for larger Bitcoin blocks, but there is still no consensus among all players in the Bitcoin ecosystem about the matter. We too believe that Bitcoin needs to start using larger blocks in the future in order to be able to scale up with the increased usage, but as to how this should be implement is a different story however.

ethereum-suprnova-mining-pool

It seems that there is new wave of Ethereum Ether (ETH) mining pools, but the good news is that the next new pool is not operated by some unknown entity, but is instead launched by Suprnova. This means a familiar interface for miners that requires registration, but if you already have one for any of the other Supernova pools you can also use it for their Ethereum pool as well. And while the new Ethereum Supernova pool is still in live beta as it is still being worked on, you can expect good quality of service and reliability, as well as response to possible issues. So definitely a place you might want to check for your Ethereum mining pool needs. The Suprnova Ethereum mining pool allows for automatic and manual request of payouts at any time provided that you have a balance of minimum 0.01 ETH and there is a 0.001 ETH transaction fee applied to payouts, the pool fee is 1%.

Getting started with Suprnova:
ethminer -G -F http://eth.suprnova.cc:3000/yourworker.1/20

The above command line is an example you can use to get started mining with ethminer at Supernova, you just need to replace the example yourworker.1 with your own worker and the default hashrate value of 20 (suitable for a single high-end GPU such as Radeon 280X) to the respective hashrate of your mining rig and you are ready to go (registration is required for the pool and you need to create workers if you don’t already have). The above example is for mining using the OpenCL version of ethminer, for using the CUDA fork you need to replace the parameter -G with -U and you should be ready to go. If you are new to Ethereum you might want to first check out our Quick Guide on How to Mine Ethereum on Windows as a good starting point.
