litecoin-network-difficulty-on-the-rise

With the shipment of more and more Scrypt ASIC miners the network difficulty is still on the rise and the percentage it increases at each difficulty readjustment is increasing as well. At the same time the price of the Litecoin remains under $8 USD with the most likely reason being that there are more sell orders and buy orders due to new miners willing to get as fast as possible ROI of their ASIC mining hardware. As a result these people mine LTC and sell it immediately and thus the exchange rate is going down and people start panicking about the future of Litecoin. This also makes more and more people rethink their plans for purchasing, especially on pre-order, new Scrypt ASIC miners.

What you can do to actually get better profit mining LTC and at the same time help in bringing the exchange rate up and not down is to mine in multipools such as LTC Rabbit and Coin King and others where you mine the most profitable Scrypt coin and can get payments in Litecoins. This helps LTC in a way that you are usually getting slightly higher profit than directly mining for Litecoins and the miner altcoins are sold for BTC and the earnings in BTC are used for purchasing LTC. This creates more buy support for the Litecoin, though it might not be as good for other alternative Scrypt crypto currencies such as DOGE that is suffering quite a lot because of this mining method used by multipools. Do note however that mining in a multipool does not always mean you will be getting better profit as often the pool might be mining directly for LTC if there is no more profitable alternative crypto currency.

Lately there is much talk about power efficiency of various mining algorithms and with the summer here people with GPU mining rigs are looking for algorithms that use less power and thus the video cards run cooler and quieter. We are starting a series of tests with GeForce GTX 750 Ti GPU first and then we are also going to move to other popular video cards for mining crypto currencies such as the Radeon R9 280X for example.

gtx-750-ti-idle-test-system-power-usage

On the photo above you can see the power usage of the GTX 750 Ti video card in idle as well as the idle power usage of the whole system we are using for testing; below you can find the specifications of the hardware. Note that one of the power meters measures only the power usage of the video card (the power meter is attached to the power line going to the card directly and all power going to it passes through the meter, so it does not take into account the PSU power efficiency) and the other one is for the whole system measured at the wall (the actual full power consumption) taking into account the efficiency of the power supply (extra power wasted as heat during the conversion).

The systems we are using for the tests include:
– Palit GeForce GTX 750 Ti StormX OC 2GB video card
– Intel i3-4130 dual-core CPU at 3.4 GHz
– Asus H81M-A Motherboard
– 2x 4GB A-DATA DDR3 1600 MHz Memory
– 1TB Seagate 7200 RPM Hard drive
– 500W Cooler Master Power Supply

gtx-750-ti-power-usage-algorithms

We have used ccMiner for our tests, the latest fork with Fresh algorithm support and we have measured the power usage of the GPU only as well as of the whole system with all of the supported algorithms by that particular version of ccMiner. Do note that if mining for Scrypt for example you will be getting higher power usage, but this is already pretty pointless to be done with GPUs with so many Scrypt ASIC miners already deployed. The results we’ve seen on the GTX 750 Ti are pretty interesting; it seems that the most power efficient algorithms are Fugue256 and HEFTY1 with the new Fresh algorithm following close by with the same power usage as Qubit. The worst performing crypto algorithms on GTX 750 Ti are the Groestl-based ones and the X-ones are pretty much in the middle. Do note however that these are the results measured on GTX 750 Ti, the situation with AMD with the same algorithms may differ significantly and we do plan to run some tests to check the situation there as well, so stay tuned for more very soon, probably tomorrow.

gtx-750-ti-power-usage-meter-2

Since there were some questions and people doubting our measurements, we have repeated the tests with another power meter connected to measure the power going only to the video card and the results are pretty much the same as with the previous meter in terms of power usage as you can see on the photo above. Do note that the Palit GeForce GTX 750 Ti video card that we have used for testing does not have an external PCI-E power connector available, so all of the power going to the video card is from the PCI-E slot. So in order to measure the exact power used by the video card we have used a powered PCI Express x1-x16 USB 3.0 Extender. This extender does not use USB 3.0 interface, just a USB 3.0 data cable for the transmission of data between the PCI-E slot on the motherboard and the video card (no power is transmitted over that cable). Instead the power provided to the video card all goes through the 4-pin Molex power connector on the extender’s board. Also do note that the power measured is coming directly from the power supply, so this measurement for the power usage of the GPU does not take into account the power efficiency of the power supply (loses of power during the conversion from 110V/220V to 12V) and depending on the power supply there will be about 10-20% of extra power lost as heat during the conversion. This power is measured by the second power meter that does measure the full system’s power consumption at the power socket however.

In the last month or so we have seen a steady increase in the network difficulty of Litecoin, the second biggest crypto currency at the moment after Bitcoin, in terms of market capitalization. This is direct result from more and more Scrypt ASIC miners being shipped to customers by companies such as Gridseed, Zeus and Innosilicon, even though most of the GPU miners have already moved to other crypto algorithms that do not yet have ASICs such as X11, X13 and others. What we are essentially seeing is centralization of the Scrypt mining hashrate in the hands of larger miners and mining farms, even though there are still quite a few small miners that have purchased some of the more affordable Gridseed and ZeusMiner Scrypt ASIC miners. In fact, what is getting more attractive for the normal small time miner are the services offering to host miners or even for cloud mining, as these cloud be easier to calculate and are more predictable over the long term and most of all no delivery times, extra cost and having to manage and monitor hardware all of the time. Unfortunately there is yet not enough competition like in the Bitcoin cloud mining segment for such services, so the price and features offered to customers are not yet that great, but hopefully we are soon going to see some more advancement in this field as well.

At the same time, with Litecoin getting harder to mine because of the increase of the network difficulty, what we are seeing is also a decrease of the price instead of increase. Interestingly enough, up until recently, Litecoin’s price was reacting pretty much the same way as Bitcoin’s, so it went up and down as the price of BTC increased or decreased, but that is not happening anymore. If this is a good sign or not is still early to tell, but since LTC is not yet as established as Bitcoin and the hardware manufacturers, especially the companies making ASIC miners may still see LTC as an extra source of income, apart from their sales of mining hardware, by mining in their own mining farms and dumping coins on the market instead of using some of their profits in order to support the crypto currency to be able to sell more hardware. As the moment with the current prices of most Scrypt ASICs and the performance they offer it is hard to decide to invest in them or not, especially when knowing that in a month or two there will be much more powerful solutions starting to hit the market, products that will seriously increase the network difficulty.

Furthermore, apart from LTC (number two) and maybe DOGE (currently number 7 in terms of market cap), there are no other more established and serious in terms of market capitalization Scrypt-based crypto currencies among the top 20. Feathercoin (FTC) is the closest one that takes the third place in terms of market capitalization among Scrypt crypto currencies in 23rd place at the moment, but it is much smaller than DOGE, let alone LTC. Then there is Karmacoin at 26th place, however the team behind this coin has already announced plans to move away from Scrypt, CureCoin at 27th place, PotCoin is 28th and a few others close by. There are also not a lot of new Scrypt-based coin launches happening lately, with maybe only Razor being a more interesting recent launch. So what will be the near future of Litecoin and other Scrypt currencies, it is still hard to predict, but we are still remaining positive about it and hope to see more decentralization of the network, instead of centralization as that is never a good thing in the world of crypto currencies.
