Today we did some calculations to see what is the actual profit that we are getting from various Bitcoin and Litecoin cloud mining services based on the earnings from yesterday. We’ve used 1000 GHS or 1 THS as a base for Bitcoin cloud mining and 1 MHS as a base for Litecoin cloud mining so that we can compare the different services listed below. The list does not contain all of the cloud mining services we are using as some of them are not even worth mentioning as there is no much point in investing in them with their current prices for hashrate. Also some other services are not listed as we are having trouble to accurately figure out how much we have earned exactly for the last 24 hours. Do note that the numbers listed below at the actual coins mined for 24 hours with maintenance fees already deducted, so this is what you are actually be getting per day (based on yesterday’s payments). Do note that the list below is based only on the actually profit that the services provide, it does not take into account the price of the hashrate that each of the services currently has.

BTC Earnings for 25.11.2014 per 1000 GHS:
Bitcoin Cloud Services BTC – 0.01248 BTC per THS Daily (1 THS price – 1.5 BTC)
Genesis Mining BTC – 0.00964 BTC per THS Daily (2.114 BTC – $779 USD)
PBMining BTC – 0.01117 BTC per THS Daily (1 THS price – 1.4 BTC)
Hashie BTC – 0.00739 BTC per THS Daily (1 THS price – 1.2 BTC AMHash / 1.30403 BTC Gen1)
ZeusHash BTC – 0.00642 BTC per THS Daily (1 THS price – 1.5315 BTC)
Hashnest BTC – 0.00548 BTC per THS Daily (1 THS price – 1.125 BTC)
CEX BTC – 0.00317 BTC per THS Daily (1 THS price – 1.6914 BTC)

LTC Earnings for 25.11.2014 per 1 MHS:
Genesis Mining LTC – 0.01143 LTC per MHS Daily (1 MHS price – 5.02 LTC / $17.99 USD)
ZeusHash LTC – 0.00423 LTC per MHS Daily (1 MHS price – 4.47 LTC / 15.99 USD)

We are not including GAW’s Hashlets as we have actually sold ours a few days ago and are currently waiting to see what new things we are going to be getting announced in the next days – PayBase, HashStaker and PayCoin. It is also interesting to note that Hashnest has apparently introduced a market for users to trad the UMISOO Bitcoin cloud hashrate that they have purchased, so you get an interesting opportunity to sell some of your hashrate at a good price or maybe buy more cheaper to possibly reach ROI faster, though the service does not currently perform so great based on actual earnings and only CEX is performing worse in our list. ZeusHash is currently not doing very well for both BTC and LTC, even though they try to attract users with various incentives and promotions all of the time, their main problem is the higher maintenance fees. Genesis Mining remains as one of the best and choices in terms of profitability, especially for people that might have some concerns about services such as PBMining or BTCCS. Also note that the numbers for some of the services might be slightly higher that what we are actually getting, for example Hashie with AMHash contracts only would get slightly better results as we have mixed hashrate with their Gen1 and AMHash hashrate, CEX also supports merged mining and the number we have above is only for the BTC earnings and does not include the merged coins.


Back in September with the release of the new Maxwell-based NVidia GPUs, the GTX 970 and GTX 980 we did some performance testing of the GeForce GTX 980 hashrate using the available at that time ccMiner and CudaMiner miners. Today, a bit over two months later we’ve decided to check how hings have progressed in terms of performance improvements of the various crypto mining algorithms with the latest optimizations available in ccMiner. We’ve used the just posted Maxwell-optimized ccMiner 1.5-git ccMiner fork from SP to get the performance results from the same GTX 980 GPU running at stock frequencies (overclocking can further increase performance).


There is no surprise that there are some significant performance improvements in various crypto algorithms that have been achieved using various optimizations, but to our surprise there ware a few algorithms that did perform worse. The results we got from Groestl, HEFTY1 and JHA were a bit lower with the latest ccMiner than what we got in terms of performance back in September. Some other algorithms also don’t seem to have very big performance improvements such as Keccak, Luffa512 or NIST5, but the more popular and still profitable to mine algorithms do come with nice improvements. You can thank for the increase in performance to all of the developers that continue to work actively and optimize the performance out of which SP and tpruvot seem to be the most active lately, djm34, tsiv as well as others who have contributed code and also Christian Buchner and Christian H. – the creators of the ccMiner in the first place. Their code contributions and efforts in releasing their work publicly deserve some appreciation from the miners who are using Nvidia GPUs in order to keep them motivated. Below you can find the official donation addresses where you can send some coins for a beer or more to the each of the developers:

Hashie is a new Bitcoin cloud mining service that we’ve been keeping an eye on, it has been available for a bit over a month already, so we’ve decided that it is time to give it a try. The website is registered on October 9th and apparently the service operators want to operate the service anonymously and keep a low profile, like many other similar services, though this does rise some concern among users that are considering to invest in such a service. This is precisely why we gave some time before actually trying out the service ourselves. The main page of the service is pretty basic and does not give a lot of information about the service, you need to register in order to properly check it out and see all the features available to you. What we like is that the service operators seem pretty active in developing the service and have been adding new features all the time, though some of them do need a bit more work to be really good and optimally useful for the miners. We’ll be talking about these in a bit as well as covering what else is needed to make the service better based on our experience and opinion, but so far what we are seeing is very promising.


Up until today the service offered their Generation 1 miners for customers at a price of $4.90 USD per 10 GHS with $0.002 USD per GHS daily maintenance fee with some additional price discounts for volume purchases that can bring down the price per 10 GHS down to $4.51 USD. Today the service however announced their partnership with the AMHash mining farm that is apparently operated by ASICMiner and RockMiner and has started offering cloud mining contracts from that service provider. The old Generation 1 contracts are still available, however the new AMhash ones are are priced lower at 0.0012 BTC per GHS and have a lower daily maintenance fee of $0.00163 USD per GHS. Both contracts are unlimited and continue until the mined coins are more than what you need to pay for maintenance fees with instant activation. The Hashie service also offers 10 GHS free miner for everyone that registers to test the service, however until you purchase some cloud mining hashrate you are not able to withdraw any of the mined coins from the free miner. The minimum purchase you can go for is 20 GH and the payments are made with BTC, in order to purchase hashrate you need to send the coins you your account’s wallet – only 3 confirmations are required before you can spend the BTC for hashrate.


The service has a market where you can put for sale your hashrate if you want to sell it to get cash faster, there are already some offers available, however there is a bit of a problem with the market at the moment. You are not able to purchase just a part of the hashrate put on sale by a user of the service, you need to buy it all, so this makes it harder to actually use this feature. Also the new AMhash cloud hashrate is not yet trade-able on the Market, only the Generation 1 is. The good thing about the market is that you might be able to get a better price per GHS, especially when purchasing bigger amounts of hashrate. Again, buying on the Market requires you to already have the needed amount of Bitcoins available in your account’s wallet and you can of course not only buy, but also sell your purchased hashrate should you decide so. You also have the option to Rename, Merge and Split your miners as every purchase you make becomes a separate miner instance and you can also use the Auto-rebuy functionality to automatically reinvest some of the earnings in more hashrate.


The service has daily payouts, but they are not automatically sent to your Bitcoin wallet, just credited to your service account and you can withdraw them after that if they meet the minimums set. The minimum withdraw amount is 0.0012 BTC and there is a 0.0002 BTC fee that will be subtracted from the amount you decide to withdraw to your Bitcoin wallet. The thing that is not so nice is that you actually don’t know how much you will earn on a daily basis, there is no estimation provided by the service, you need to wait for the daily payout to be executed to see how much you have earned for the previous day. This means that you do not get earnings credited when a block is solved, this happens once every 24 hours automatically and you need to check the Transactions log after that to see how much you have mined with your hashrate available. The good thing is that there is a detailed information in the transaction log on how much was actually mined and what were the electricity fees you have paid etc., so it is quite useful and detailed. It would’ve been nice to also get a statistics for things like mined this week or month, since the start etc. to make it easier to keep a track of your ROI as this is important for miners.

So far we like what we are seeing as functionality of the service and it seems to work pretty well, though the functionality does need some more improvements to make it even better it does seem like a cloud mining service to keep an eye on. We are going to continue testing it and reporting our experience as time goes by, but so far things are looking promising and the price per GHS and the maintenance fees does seem to be one of the best currently available, especially with the new AMhash contracts just introduced. If you just want to check the service out you can register and claim your free 10 GHS miner, it is quick and completely free to do it and then decide if you should invest in more hashrate. We started like that, then bought some Generation 1 hashrate and now we are also going to be purchasing some AMhash cloud mining hashrate as well to see how it goes. As usual when considering to invest in cloud mining services do not put all of your investment in just one place and never spend more than you can afford to loose.
